Record Year

Record Year 

In 2006, we continued to set performance records. 

For a third consecutive year, both railway operating 

revenues and income from railway operations 

reached record levels. 

Net income of $1.5 billion set a record for the third 

consecutive year, as did our $3.57 earnings per share. 

Stockholders benefited from a fifth consecutive year 

of dividend increases. In 2006, two dividend increases 

resulted in a 42 percent increase in dividends paid.

In November 2005, our board of directors authorized 

the repurchase of up to 50 million shares of our 

common stock through 2015. As an indication 

of our confidence in the strategic direction of 

our company, we repurchased almost 22 million 

shares of our common stock in 2006. 

We continued to reduce outstanding debt, and we  

lowered our debt to total capitalization ratio to 

40.7 percent as of the end of 2006. Our operating 

ratio, a standard measurement of performance 

efficiency, improved to 72.8 percent.

Record Year

General 
Merchandise

General merchandise revenue was $.1 billion in 

2006, an 11 percent increase over 200, reflecting 

higher average revenues, including fuel surcharges. 

All commodity groups set revenue records, with the 

exception of automotive, which was within 2 percent  

of its all-time high. Following are some of the factors  

that affected the five commodity groups. For a full  

discussion of the change in revenues, refer to 

Management’s Discussion & Analysis included in  

the Form 10-K section of this annual report.

Agriculture, Consumer  
Products & Government

Paper, Clay & Forest Products

The paper, wood and kaolin clay markets were mixed 

in 2006. While we experienced improvement in the 

printing paper market, driven by new import business, 

lumber and wood products declined in the face of a 

weaker housing market. 

As landfill capacity in the Northeast has diminished,  

demand for long-haul rail service for municipal solid waste 

shipments has increased. New landfills located on NS 

lines in the Midwest and Southeast are expected to con-

tinue to drive opportunities for business growth in 2007. 

Metals & Construction

Continued strength from both foreign and domestic steel 

markets for most of the year drove volume growth for 

Ethanol was the leading story for 2006. Ethanol  

metals. NS remains an industry leader in the metals trans-

production soared, and rail emerged as a preferred 

portation market, serving 19 integrated mills, 17 electric 

mode of transport. We handled ethanol through 18 

arc mills, more than 0 major steel processors and 7 

distribution facilities in 2006, and in 2007, additional 

steel distribution facilities. As the construction market for 

ethanol distribution facilities are expected to come on 

new housing softened, transportation demand from high-

line to meet the growing demand. Military shipments, 

way and nonresidential construction increased. Access to 

traffic related to Hurricane Katrina recovery efforts 

new stone quarries and terminals generated new business 

and grain to the growing southeast feed industry also 

that we believe will continue to expand in 2007 and beyond.  

contributed to revenue.

Chemicals

The plastics, petroleum, industrial intermediates and 

miscellaneous chemicals markets grew in 2006.  

Industrial development efforts led to several new plastics 

plants and expansions along our lines during the year 

that helped mitigate weaker demand early in the year, 

when producers were ramping back up to pre-Katrina levels. 

NS intends to add to its transload terminal network and 

open a new Thoroughbred Bulk Terminal in Somerset, Ky., 

in 2007, bringing the total number of terminals to 1. 

Automotive 

Softening North American vehicle production resulted 

in fewer automotive shipments for NS in 2006. NS-

served assembly plants closed in St. Louis and Atlanta, 

as did an offline Oklahoma City assembly plant for which  

NS was an interline carrier. However, growth from other  

manufacturers, including the recently expanded NS-served  

Mercedes-Benz assembly complex in Vance, Ala., offset 

some of these declines. In 2006, NS received Toyota’s 

President’s Award for Logistics Excellence and Toyota’s 

Excellence Award for On-Time Performance.

 
12

Intermodal

As international trade remains strong and U.S. highways become increasingly congested, demand for intermodal 

transportation continues to grow. NS experienced a  percent increase in volume and an 8 percent increase in revenue 

over the previous year, driven by higher average revenues, fuel surcharges and volume. To meet the needs of intermodal 

customers today, and to prepare for future growth, we have invested in several projects to increase capacity and improve 

service. Projects in the works today include: the Heartland Corridor, to enable double-stacked containers to travel directly 

from the mid-Atlantic to the Midwest; the Rickenbacker intermodal facility in Columbus, Ohio; and the Meridian Speedway, 

to improve service between Meridian, Miss., and Shreveport, La. In August, we opened our newest intermodal facility 

at Appliance Park in Louisville, Ky. The 2-acre facility will enable NS to increase capacity and provide more efficient 

rail services for the Louisville market, which has seen significant intermodal traffic growth over the past several years.

Coal

2006 was a record revenue year for the coal business group, with gains of $21 million, or 10 percent, over the previous 

year, reflecting higher average revenues, including fuel surcharges, and increased volume. The utility sector, which 

comprises 78 percent of the coal business group’s tonnage, rebuilt stockpiles as a result of record utility volumes and 

mild weather in our service region. Additionally, demand for domestic metallurgical coal grew because of increased 

spot business at domestic steel plants. Though the utilities and domestic metallurgical coal sectors were strong, the 

export coal market softened in 2006 as Asian receivers returned to their traditional suppliers, after having turned to 

the U.S. in 200 when global supplies were tight.

Norfolk Southern employees are the heart 

of our operation. Behind every new tech-

nology, every mile of track we lay and every 
customer delivery are our employees 
who work to make it happen. To continue to  

provide our customers with safe, reliable 

and efficient transportation of their 

goods, and to best serve our communities, 

we are recruiting and developing a work 

force trained to provide top-quality service.

Building a Work Force  
for Tomorrow

NS is preparing for tomorrow by leading an aggressive  

recruiting effort today. To build and maintain a strong, diverse 

work force, NS’ approach to recruiting looks both inside and 

outside the company to fill its management ranks. We recruit 

recent college graduates for a comprehensive 1-month 

Bob Knowles, NS terminal trainmaster

management training program. We also recruit men and 

women with management experience in other industries and 

look to current NS employees to enter our new operations 

supervisor training program designed to prepare individuals 

to fill supervisory positions. Similarly, we encourage managers 

performing other functions in the company to consider  

midcareer transitions to jobs in operations.   

With a sizeable percentage of our work force eligible to 

retire in the next 10 years, we recognize that we need to 

be aggressive and innovative in our recruitment efforts. We 

are working to strengthen our partnerships with universities 

across the country. In addition to visiting college campuses 

and inviting students to interview with NS, we sponsor  

scholarships, campus lectures highlighting the variety of 

opportunities on the railroad, and projects for students to 

gain real-life engineering experience. In 2006, a project that 

NS supported at North Carolina State University won first  

Military Background and NS Training put  
Bob Knowles on Track for Growth  
in a Railroad Career

Bob Knowles, a terminal trainmaster at Enola 

Yard in Harrisburg, Pa., says his background 

with the United States Army is a natural fit for a 

career with the railroad. He is used to being part 

of a team where each person’s effort is neces-

sary for success. Having served in Iraq, he’s also 

accustomed to challenging work in a demanding 

environment where safety is the top priority.  

In his position, Bob ensures that all of the trains 

in Enola Yard are in position and that employees 

are scheduled so that NS can make on-time  

deliveries to its customers. Skills Bob honed in 

the Army, particularly effective communication, 

have helped him earn three promotions since 

place in the National Student Safety Engineering Design Contest. 

he was hired as a conductor in the spring of 200.   

We also place significant emphasis on recruiting former 

members of the military. Veterans bring to NS a heightened 

awareness of safety and a commitment to teamwork — two 

attributes we value highly at the railroad. A full-time NS 

recruiter regularly visits military installations, part of a 

campaign that led G.I. Jobs magazine to rate NS as one of 

the nation’s top military-friendly employers.  

In addition to his military background, Knowles 

attributes his growth at NS to the employee 

development opportunities the railroad provides. 

According to Knowles, “A well-trained employee 

is not only more efficient, he’s also safer on the job.”  

In the span of two years, Knowles has taken  

27 courses on topics ranging from time  

management to delegation strategies.

Putting Safety First

Safety is the top priority at NS.  We work hard to 

achieve an injury-free workplace, with a goal of zero 

incidents and zero injuries. NS has systemwide safety 

policies and emphasizes safety training, and our employees 

make safety their personal commitment on the job. 

Sustaining our commitment to safety allows us to offer 

customers a competitive transportation package while 

also serving the interests of our employees, communities 

and stockholders.

For 17 years running, we have won the E.H. Harriman 

Gold Medal award — the highest award in the rail 

industry for employee safety. That says a lot about the 

standards we set for our employees — and about  

how seriously our employees take that responsibility. 

Andrea Hogue, mechanical supervisor,  
Juniata Locomotive Shop, Altoona, Pa.

The foundation of Norfolk Southern’s safety  
practices is found in its Six Tenets of Safety: 

1.   All injuries can be prevented.
2.   All exposures can be safeguarded.
.   Prevention of injuries and accidents  
is the responsibility of each employee.

.   Training is essential for good safety performance.
.   Safety is a condition of employment.
6.   Safety is good business.

Strengthening our Work Force 

At NS, training is more than just a way to prepare new 

School. This four-day program, held in Norfolk, launches 

employees — it  is part of our culture. We believe that em-

NS Employees Find Invaluable Experience  
in New Career Tracks

NS is always on the search for men and women qualified to 

handle the challenge of serving on the front lines in operations. 

In Laura Hoag, Coleman Lawrence and Robyn Louderback 

— three employees in very different parts of the company —  

NS found individuals eager for the challenge. Laura, Coleman 

and Robyn represent a growing trend at NS: employees who 

choose to make a midcareer transition to positions in operations.    

In May 2006, after working eight years in Norfolk Southern’s 

labor relations department, Laura decided it was time to 

expand the scope of her experience. At the encouragement of 

her supervisors and peers, she decided to apply for the job of 

assistant terminal superintendent in Decatur, Ill., the position 

she holds today. “Switching from an office job at NS headquarters 

to a yard in Decatur, Ill., was out of the ordinary,” said Laura. 

“But once I made the decision, I never looked back. I’m so 

thankful for this opportunity and the positive impact it has  

had on my career.”    

Nine years in the marketing and finance departments gave  

Coleman a thorough understanding and a well-rounded per-

spective of NS as a company. When he was ready for a new 

challenge, NS recognized the value of Coleman’s experiences, 

and, in his words, “gave me the opportunity to test my skills in a 

more hands-on leadership role.” As the terminal superintendent 

in Atlanta for the past year, Coleman has gained a greater  

understanding of all that it takes to make NS run, and an even  

greater appreciation for the people who do it. “In the marketing  

department, I was charged with planning, designing and 

promoting excellent customer service. In the yard, I’m  

charged with making it happen.”    

Before making her transition, Robyn had served in various 

capacities in NS’ marketing department. After seven years, 

Robyn decided to make the move to operations because she 

realized that the experience would enable her to better serve 

the company and its customers. She served a year as as-

sistant terminal superintendent in Chicago before returning 

to marketing this year as manager business development in 

the agricultural, consumer products & government merchan-

dise group. In Chicago, she learned firsthand the company’s 

commitment to providing safe, efficient services to customers. 

While her routine and responsibilities were drastically different 

from her previous jobs, Robyn said, “There is no experience like 

working on the front lines. It’s invaluable.”

Technology Drives 
Performance

We know we need to do more than simply strive to  

improve performance. We want to know with certainty 

that we are improving. In 2006, we introduced a system 

to share information about shipment and train perfor-

mance with employees across the network at every 

level of the company. NS employees are able to see how 

their individual and team performance directly impact 

our overall performance and how their specific location 

compares to performance at other locations around the 

system. This facilitates greater individual visibility and 

leads to continuous improvement.

At the same time, we are leveraging our investment 

in wireless technology to make information needed 

to manage our operations accessible to more of our

Building Capacity  
for the Future

International trade, highway congestion, the rising  

cost of energy, and the demand for utility coal all drive 

the need for more rail capacity. At Norfolk Southern, 

we are working to meet these needs through strategic 

investment in new infrastructure. NS employs a multi-

disciplined process that evaluates capacity needs to 

determine financial and operational implications.  

After extensive review with local field personnel and 

evaluation of train operating information, congestion 

points are identified. Using sophisticated modeling and 

simulation tools, potential capital improvements are 

identified and evaluated to determine the most cost-

effective improvements available. Today, we are focusing 

particularly on investments that will accommodate con-

tinued growth in intermodal traffic, whereby railroads 

interchange freight with truck and shipping lines to 

transport goods to their final destinations. We also are 

working with federal, state and local governments to 

implement large-scale transportation projects that will 

have a positive impact on commerce and trade.

 The Heartland Corridor

Today, double-stacked containers traveling by rail from 

the port of Norfolk to Columbus or Chicago must take 

a circuitous route through Harrisburg, Pa., or through 

Chattanooga, Tenn., to reach their destinations. The tunnels 

through the Virginia and West Virginia mountains are 

too low for double-stacked containers to pass through. 

The Heartland Corridor Project is changing that. We are 

working with the federal government and with the states 

of Ohio, West Virginia and Virginia in a public-private 

partnership to improve the corridor with a shared invest-

ment of $11 million. When the Heartland Corridor is 

completed over the next three years, the enhanced route 

is expected to increase capacity, improve service con-

sistency and shave an entire day off the journey from the 

mid-Atlantic to the Midwest for double-stacked containers.

extensions totaling . additional miles in Meehan and 

Rankin, Miss., and Stevens, La. With completion of 

these projects expected in 2007, it will be much easier 

for trains to meet and pass, thereby increasing capacity.

The Shelocta Secondary

The demand for utility coal is growing, and we stand 

ready to meet that need. In 2006, we ran our first train 

on the new Shelocta Secondary. The new service is the 

result of a $ million project to establish a direct rail 

connection between the NS Conemaugh Line in Saltsburg, 

Pa., and the coal-powered Keystone Generating Station 

in Shelocta, Pa. By replacing a circuitous route with 

limited capacity, the Shelocta Secondary trims 1 miles 

off the trip from Saltsburg to Shelocta. The new route 

efficiently increases capacity to the plant, allowing for 

faster cycle times and longer trains.

CREATE

The Chicago Region Environmental and Transporta-

tion Efficiency program, CREATE, is a first-of-its-kind 

partnership among the state of Illinois, the city of 

Chicago, Metra, and the nation’s freight railroads, 

including Norfolk Southern. A project of national 

significance in the nation’s busiest freight transpor-

tation hub, CREATE will invest $1. billion in critically 

needed rail infrastructure improvements designed  

to improve the quality of life of Chicago-area residents 

and increase the efficiency of freight and passenger 

rail service throughout the region. 

The rail industry has agreed to match $100 million 

in approved federal funds for CREATE. The first 

phase of the project will assign $21 million to 

rail projects in the Chicago area. During 2006, 

environmental studies and preliminary engineering 

design work continued on 22 rail projects, and two 

highway-rail grade separation projects were under 

construction. Construction is scheduled to start on 

seven rail projects in 2007, with completion of most 

expected in 2008. 

The Shelocta Secondary, which 

was completed in 2006, increases 

capacity and improves routing for 

coal traffic between Saltsburg 

and Shelocta, Pa.

Conserving  
Fuel, Protecting  
the Environment 

Serving our communities means continually striving to 

minimize our impact on the environment. In 2006, we 

began rolling out Locomotive Engineer Assist Display 

and Event Recorder® in locomotives across the Virginia 

Division. Early estimates are that this will reduce fuel 

consumption by 7 percent on an average run.

Also in 2006, we equipped our first locomotives with 

generator-set engines. Unlike conventional locomotives 

powered by a single engine, locomotives with “gen-sets” are 

powered by multiple engines. With multiple engines, we can 

modulate the number of engines used at any given time, de-

pending on the horsepower needed. That allows us to burn 

less fuel, resulting in fewer emissions and greater efficiency.

NS is looking for other ways to protect the environment 

through its own initiatives and in partnership with the 

U.S. Environmental Protection Agency. For instance, we

This benefit increased net income by $96 million, or 2 cents per diluted share. 
2 200 other income — net includes a $0 million net gain from the Conrail corporate reorganization. This gain increased net income by $0 million, or 10 cents per diluted share.
 200 operating expenses include a $107 million charge for a voluntary separation program. Other income — net includes an $8 million charge to recognize the impaired    
value of certain telecommunications assets. These charges reduced net income by $119 million, or 0 cents per diluted share.
  NS sold all the common stock of its motor carrier subsidiary, North American Van Lines, Inc., in 1998. Results in 200 include an additional after-tax gain of $10 million, or

 200 reflects two accounting changes, the cumulative effect of which increased net income by $11 million, or 29 cents per diluted share: a change in accounting for the cost 
to remove railroad crossties, which increased net income by $110 million; and a change in accounting related to a special-purpose entity that leased certain locomotives to NS,  
which increased net income by $ million.

NORFOLK SOUTHERN CORPORATION AND SUBSIDIARIES (NS) 

Item 1.  Business.  and Item 2.  Properties. 

GENERAL - Norfolk Southern Corporation (Norfolk Southern) is a Norfolk, Virginia based company that 
controls a major freight railroad, Norfolk Southern Railway Company.  Norfolk Southern Railway Company is 
primarily engaged in the rail transportation of raw materials, intermediate products and finished goods primarily 
in the Southeast, East and Midwest and, via interchange with rail carriers, to and from the rest of the United 
States and parts of Canada.  Norfolk Southern also transports overseas freight through several Atlantic and Gulf 
Coast ports.  Norfolk Southern provides comprehensive logistics services and offers the most extensive 
intermodal network in the eastern half of the United States.  The common stock of Norfolk Southern is listed on 
the New York Stock Exchange (NYSE) under the symbol “NSC.” 

Norfolk Southern was incorporated on July 23, 1980, under the laws of the Commonwealth of Virginia.  On 
June l, 1982, Norfolk Southern acquired control of two major operating railroads, Norfolk and Western Railway 
Company (NW) and Southern Railway Company (Southern) in accordance with an Agreement of Merger and 
Reorganization dated as of July 31, 1980, and with the approval of the transaction by the Interstate Commerce 
Commission  (now the Surface Transportation Board [STB]).  Effective Dec. 31, 1990, Norfolk Southern 
transferred all the common stock of NW to Southern, and Southern's name was changed to Norfolk Southern 
Railway Company (Norfolk Southern Railway or NSR).  Effective Sept. 1, 1998, NW was merged with and into 
Norfolk Southern Railway.  As of Dec. 31, 2006, all the common stock of Norfolk Southern Railway was owned 
directly by Norfolk Southern. 

Through a limited liability company, Norfolk Southern and CSX Corporation (CSX) jointly own Conrail Inc. 
(Conrail), whose primary subsidiary is Consolidated Rail Corporation (CRC).  Norfolk Southern has a 58% 
economic and 50% voting interest in the jointly owned entity, and CSX has the remainder of the economic and 
voting interests.  CRC owns and operates certain properties (the Shared Assets Areas) for the joint and 
exclusive benefit of NSR and CSX Transportation Inc. (CSXT).  On June 1, 1999, NSR and CSXT began 
operating separate portions of Conrail’s rail routes and assets.  On August 27, 2004, NS, CSX and Conrail 
completed a corporate reorganization of Conrail (Conrail Corporate Reorganization), which established direct 
ownership and control by NSR and CSXT of two former CRC subsidiaries, Pennsylvania Lines LLC and New 
York Central Lines LLC, respectively (see Note 4 to the Consolidated Financial Statements). 

Norfolk Southern makes available free of charge through its website, www.nscorp.com, its annual report on 
Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports as 
soon as reasonably practicable after such material is electronically filed with or furnished to the Securities and 
Exchange Commission (SEC).  In addition, the following documents are available on the company’s website and

and iron ore accounted for about 25% of NS' total railway operating revenues in 2006. 

Total coal handled through all system ports in 2006 was 33.8 million tons.  Of this total, 10.8 million tons 
(including coastwise traffic) moved through Norfolk, Virginia, 2.4 million tons moved through the Baltimore 
Terminal, 13.0 million tons moved to various docks on the Ohio River, and 7.6 million tons moved to various

Lake Erie ports.  Other than coal for export, virtually all coal handled by NS' railroads was terminated in states 
east of the Mississippi River. 

See the discussion of coal traffic, by type of coal, in Part II, Item 7, “Management's Discussion and Analysis of 
Financial Condition and Results of Operations.” 

GENERAL MERCHANDISE TRAFFIC - General merchandise traffic is composed of five major commodity 
groupings:  automotive; chemicals; metals and construction; agriculture, consumer products and government; and 
paper, clay and forest products.  The automotive group includes finished vehicles for BMW, DaimlerChrysler, 
Ford Motor Company, General Motors, Honda, Isuzu, Jaguar, Land Rover, Mazda, Mercedes-Benz, Mitsubishi, 
Nissan, Saab, Subaru, Suzuki, Toyota and Volkswagen, and auto parts for Ford Motor Company, General Motors, 
Mercedes-Benz and Toyota.  The chemicals group includes sulfur and related chemicals, petroleum products, 
chlorine and bleaching compounds, plastics, rubber, industrial chemicals, chemical wastes and municipal wastes.  
The metals and construction group includes steel, aluminum products, machinery, scrap metals, cement, 
aggregates, bricks and minerals.  The agriculture, consumer products and government group includes soybeans, 
wheat, corn, fertilizer, animal and poultry feed, food oils, flour, beverages, canned goods, sweeteners, consumer 
products, ethanol and items for the military.  The paper, clay and forest products group includes lumber and wood 
products, pulp board and paper products, wood fibers, wood pulp, scrap paper and clay. 

In 2006, 147 million tons of general merchandise freight, or approximately 66% of total general merchandise 
tonnage handled by NS, originated online.  The balance of general merchandise traffic was received from 
connecting carriers at interterritorial gateways.  The principal interchange points for NS-received traffic included 
Chicago, Memphis, New Orleans, Cincinnati, Kansas City, Detroit, Hagerstown, St. Louis/East St. Louis and 
Louisville.  General merchandise carloads handled in 2006 were 2.9 million, the revenue from which accounted for 
54% of NS’ total railway operating revenues in 2006. 

See the discussion of general merchandise rail traffic by commodity group in Part II, Item 7, “Management's 
Discussion and Analysis of Financial Condition and Results of Operations.” 

INTERMODAL TRAFFIC - The intermodal market consists of shipments moving in trailers, domestic and 
international containers, and Roadrailer® equipment.  These shipments are handled on behalf of intermodal 
marketing companies, international steamship lines, truckers and other shippers.  Intermodal units handled in 
2006 were 3.3 million, the revenues from which accounted for 21% of NS’ total railway operating revenues for 
the year. 

See the discussion of intermodal traffic in Part II, Item 7, “Management's Discussion and Analysis of Financial 
Condition and Results of Operations.” 

FREIGHT RATES - In 2006, NS' railroads continued their reliance on private contracts and exempt price quotes 
as their predominant pricing mechanisms.  Thus, a major portion of NS' railroads' freight business is not currently 
economically regulated by the government.  In general, market forces have been substituted for government 
regulation and now are the primary determinant of rail service prices. 

In 2006, NS' railroads were found by the STB to be “revenue adequate” based on results for the year 2005.  A 
railroad is “revenue adequate” under the applicable law when its return on net investment exceeds the rail industry's 
composite cost of capital.  This determination is made pursuant to a statutory requirement.

Regularly scheduled passenger trains are operated by Amtrak on NS' lines between the following 
locations: 

-  Alexandria and New Orleans 
-  Greensboro and Selma, North Carolina 
-  Chicago, Illinois, and Detroit, Michigan 
-  Chicago and Harrisburg, Pennsylvania 

Commuter trains are operated on the NS line between Manassas and Alexandria in accordance with 
contracts with two transportation commissions of the Commonwealth of Virginia 
NS leases the Chicago to Manhattan, Illinois, line to the Commuter Rail Division of the Regional 
Transportation Authority of Northeast Illinois 
NS provides freight service over lines with significant ongoing Amtrak and commuter passenger 
operations, and is conducting freight operations over some trackage owned by: 

-  Amtrak 
-  New Jersey Transit 
-  Southeastern Pennsylvania Transportation Authority 
-  Metro-North Commuter Railroad Company 
-  Maryland DOT 

Passenger operations are conducted either by Amtrak or by the commuter agencies over trackage 
owned by Conrail in the Shared Assets Areas. 

NONCARRIER OPERATIONS - NS' noncarrier subsidiaries engage principally in the acquisition, leasing and 
management of coal, oil, gas and minerals; the development of commercial real estate; telecommunications; and 
the leasing or sale of rail property and equipment.  In 2006, no such noncarrier subsidiary or industry segment 
grouping of noncarrier subsidiaries met the requirements for a reportable business segment set forth in Statement 
of Financial Accounting Standards No. 131. 

RAILWAY PROPERTY 

The NS railroad system extends across 22 states, the District of Columbia and portions of Canada.  The railroad 
infrastructure makes the company capital intensive with total property of approximately $21 billion. 

Capital Expenditures - Capital expenditures for road, equipment and other property for the past five years were 
as follows (including capitalized leases):

Capital spending and maintenance programs are and have been designed to assure the ability to provide safe, 
efficient and reliable transportation services.  For 2007, NS has budgeted $1.34 billion of capital spending.  On 
May 1, 2006, NS and Kansas City Southern (KCS) formed a joint venture (MSLLC) pursuant to which NS 
intends to contribute $300 million in cash, substantially all of which will be used for capital improvements over a 
period of approximately three years, in exchange for a 30% interest in the joint venture.  See the discussion 
following “Cash used for investing activities,” in Part II, Item 7, “Management's Discussion and Analysis of 
Financial Condition and Results of Operations.”

Ongoing freight car and locomotive maintenance programs are intended to ensure the highest standards of safety, 
reliability, customer satisfaction and equipment marketability.  The declines in 2006, 2005 and 2003 reflected an 
increase in maintenance activity as well as the retirement of unserviceable units.  The locomotive bad order ratio 
includes units out of service for required inspections every 92 days and program work such as overhauls.   

Encumbrances - Certain railroad equipment is subject to the prior lien of equipment financing obligations 
amounting to approximately $534 million as of Dec. 31, 2006, and $650 million as of Dec. 31, 2005. 

Track Maintenance - Of the approximately 38,000 total miles of track operated, NS had responsibility for 
maintaining about 30,000 miles of track with the remainder being operated under trackage rights. 

Over 75% of the main line trackage (including first, second, third and branch main tracks, all excluding trackage 
rights) has rail ranging from 131 to 155 pounds per yard with the standard installation currently at 136 pounds per 
yard.  Approximately 45% of NS lines carried 20 million or more gross tons per track mile during 2006.

Microwave System - The NS microwave system, consisting of approximately 7,400 radio route miles, 424 core 
stations, 14 secondary stations and 5 passive repeater stations, provides communications between most operating 
locations.  The microwave system is used primarily for voice communications, VHF radio control circuits, data and 
facsimile transmissions, traffic control operations and AEI data transmissions. 

Traffic Control - Of the approximately 16,200 route miles owned by NS, about 11,000 miles are signalized, 
including 8,000 miles of centralized traffic control (CTC) and 3,000 miles of automatic block signals.  Of the 
8,000 miles of CTC, approximately 3,000 miles are controlled by data radio originating at 244 base station 
radio sites.

Computers - A computer network consisting of a centralized data center in Atlanta, Georgia, and various 
distributed computers throughout the company connects the yards, terminals, transportation offices, rolling stock 
repair points, sales offices and other key system locations.  Operating and traffic data are processed and stored to 
provide customers with information on their shipments throughout the system.  Computer systems provide current 
information on the location of every train and each car on line, as well as related waybill and other train and car 
movement data.  In addition, the computer systems are utilized to assist management in the performance of a 
variety of functions and services including payroll, car and revenue accounting, billing, material management 
activities and controls, and special studies. 

ENVIRONMENTAL MATTERS - Compliance with federal, state and local laws and regulations relating to the 
protection of the environment is a principal NS goal.  To date, such compliance has not affected materially NS' 
capital additions, earnings, liquidity or competitive position.  See “Legal Proceedings,” Part I, Item 3; “Personal 
Injury, Environmental and Legal Liabilities” in Part II, Item 7, “Management's Discussion and Analysis of 
Financial Condition and Results of Operations;” and Note 17 to the Consolidated Financial Statements.

Approximately 85% of NS' railroad employees are covered by collective bargaining agreements with various 
labor unions.  See the discussion of “Labor Agreements” in Part II, Item 7, “Management's Discussion and 
Analysis of Financial Condition and Results of Operations.” 

GOVERNMENT REGULATION - In addition to environmental, safety, securities and other regulations 
generally applicable to all businesses, NS' railroads are subject to regulation by the STB.  The STB has 
jurisdiction over some rates, routes, conditions of service and the extension or abandonment of rail lines.  The 
STB also has jurisdiction over the consolidation, merger or acquisition of control of and by rail common carriers.  
The Federal Railroad Administration regulates certain track and mechanical equipment standards. 

The relaxation of economic regulation of railroads, begun over two decades ago under the Staggers Rail Act of 
1980, has continued.  Significant exemptions are TOFC/COFC (i.e., “piggyback”) business, rail boxcar traffic, 
lumber, manufactured steel, automobiles and certain bulk commodities such as sand, gravel, pulpwood and wood 
chips for paper manufacturing.  Transportation contracts on regulated shipments effectively remove those 
shipments from regulation as well for the duration of the contract.  About 84% of NS' freight revenues come from 
either exempt traffic or traffic moving under transportation contracts. 

Efforts may be made in 2007 to re-subject the rail industry to unwarranted federal economic regulation.  
The Staggers Rail Act of 1980, which substantially reduced such regulation, encouraged and enabled rail 
carriers to innovate and to compete for business, thereby contributing to the economic health of the nation 
and to the revitalization of the industry.  Accordingly, NS will oppose efforts to reimpose unwarranted 
economic regulation. 

COMPETITION - There is continuing strong competition among rail, water and highway carriers.  Price is 
usually only one factor of importance as shippers and receivers choose a transport mode and specific hauling 
company.  Inventory carrying costs, service reliability, ease of handling and the desire to avoid loss and damage 

K10 

  
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
  
during transit are also important considerations, especially for higher-valued finished goods, machinery and 
consumer products.  Even for raw materials, semifinished goods and work-in-process, users are increasingly 
sensitive to transport arrangements that minimize problems at successive production stages. 

NS' primary rail competitor is the CSX system; both operate throughout much of the same territory.  Other 
railroads also operate in parts of the territory.  NS also competes with motor carriers, water carriers and with 
shippers who have the additional option of handling their own goods in private carriage. 

Certain marketing strategies among railroads and between railroads and motor carriers enable carriers to compete 
more effectively in specific markets. 

Item 1A.  Risk Factors. 

NS is subject to significant governmental regulation and legislation over commercial, environmental and 
operating matters.  Railroads are subject to commercial regulation by the Surface Transportation Board, which has 
jurisdiction over some rates, routes, fuel surcharges, conditions of service and the extension or abandonment of rail 
lines.  The STB also has jurisdiction over the consolidation, merger or acquisition of control of and by rail common 
carriers.  Occasional efforts are made to re-subject the rail industry to unwarranted federal economic regulation.  In 
addition, Congress could enact re-regulation legislation.  Economic re-regulation of the rail industry could have a 
significant negative impact on NS’ ability to determine prices for rail services, reduce capital spending on its rail 
network, and result in a material adverse effect on NS’ financial position, results of operations or liquidity in a 
particular year or quarter.  

NS’ operations are subject to extensive federal, state, and local environmental laws and regulations concerning, 
among other things, emissions to the air; discharges to water ways or ground water supplies; handling, storage, 
transportation, and disposal of waste and other materials; and the cleanup of hazardous material or petroleum 
releases. The risk of incurring environmental liability – for acts and omissions, past, present and future – is 
inherent in the railroad business.  Several of NS’ subsidiaries own, or have owned, land used as operating 
property or held for sale, or which is leased or may have been leased and operated by others.  Environmental 
problems that are latent or undisclosed may exist on these properties, and NS could incur environmental liabilities 
or costs, the amount and materiality of which cannot be estimated reliably at this time, with respect to one or more 
of these properties.  Moreover, lawsuits and claims involving other unidentified environmental sites and matters 
are likely to arise from time to time, and the resulting liabilities could have a significant effect on financial 
position, results of operations or liquidity in a particular year or quarter. 

The Federal Railroad Administration regulates a host of operations matters including track and mechanical 
equipment standards; signaling systems; testing and inspection of grade crossing warning devices, hours of service 
of operating employees; drug and alcohol testing; locomotive engineer certification; and reporting of employee 
injuries, among other areas.  NS’ unintentional failure to comply with applicable laws and regulations could have a 
material adverse effect on NS, and changes in the legislative or regulatory frameworks within which NS operates 
could adversely affect its business.   

NS, as a common carrier by rail, must offer to transport hazardous materials, regardless of risk.  
Transportation of certain hazardous materials could create catastrophic losses in terms of personal injury and 
property damage costs, and compromise critical parts of our rail network.  Legislation introduced in Congress in 
early 2005 would give federal regulators increased authority to conduct investigations and levy substantial fines 
and penalties in connection with railroad accidents.  Federal regulators also would be required to prescribe new 
regulations governing railroads’ transportation of hazardous materials.  Legislation proposed in 2006 would 
require the Department of Homeland Security (DHS) to develop rail security plans and the railroads to submit 
vulnerability assessments, security plans and employee training programs to DHS for approval.  If enacted, such 
legislation and regulations could impose significant additional costs on railroads.  Regulations proposed in late 
2006 by DHS mandating chain of custody and security measures likely will cause service degradation and higher 

K11 

  
  
 
  
 
 
 
costs for the transportation of toxic inhalation hazard materials.  Further, certain local governments have sought to 
enact ordinances banning hazardous materials moving by rail within their borders.  Some legislators have 
contemplated pre-notification requirements for hazardous materials shipments.  If promulgated such ordinances 
could require the re-routing of hazardous materials shipments, with the potential for significant additional costs 
and network inefficiencies.  

NS may be affected by terrorism or war.  Any terrorist attack, or other similar event, any government response 
thereto, and war or risk of war could cause significant business interruption and may adversely affect NS’ results 
of operations, financial position, and liquidity.  Because NS plays a critical role in the nation’s transportation 
system, it could become the target of such an attack or have a significant role in the government’s preemptive 
approach or response to an attack or war.  

Although NS currently maintains insurance coverage for third-party liability arising out of war and acts of 
terrorism, it maintains only limited insurance coverage for first-party property damage and damage to property 
in NS’ care, custody or control caused by certain acts of terrorism.  In addition, premiums for some or all of NS’ 
current insurance programs covering these losses could increase dramatically, or insurance coverage for certain 
losses may not be available to NS in the future.  

NS may be affected by general economic conditions.  Prolonged negative changes in domestic and global 
economic conditions affecting the producers and consumers of the commodities NS carries may have an adverse 
effect on its operating results, financial position, and liquidity.  Economic conditions resulting in bankruptcies of 
one or more large customers could have a significant impact on NS’ financial position, results of operations or 
liquidity in a particular year or quarter.  

NS faces competition from other transportation providers.  NS is subject to competition from motor carriers, 
railroads, and to a lesser extent, ships, barges, and pipelines, on the basis of transit time, pricing, and the quality 
and reliability of service.  While NS has used primarily internal resources to build or acquire and maintain its rail 
system, trucks and barges have been able to use public rights-of-way maintained by public entities. Any future 
improvements or expenditures materially increasing the quality or reducing the cost of alternative modes of 
transportation in the regions in which NS operates, or legislation granting materially greater latitude for motor 
carriers with respect to size or weight limitations, could have a material adverse effect on its financial position, 
results of operations or liquidity in a particular year or quarter. 

The operations of carriers with which NS interchanges may adversely affect its operations.  NS’ ability to 
provide rail service to customers in the U.S. and Canada depends in large part upon its ability to maintain 
cooperative relationships with connecting carriers with respect to, among other matters, freight rates, revenue 
divisions, car supply, reciprocal switching, interchange, trackage rights and locomotive availability.  
Deterioration in the operations of, or service provided by connecting carriers, or in our relationship with those 
connecting carriers, could result in NS’ inability to meet its customers’ demands or require NS to use alternate 
train routes, which could result in significant additional costs and network inefficiencies. 

NS relies on technology and technology improvements in its business operations.  If NS experiences 
significant disruption or failure of one or more of its information technology systems, including computer 
hardware, software, and communications equipment, NS could experience a service interruption, security breach, 
or other operational difficulties, which could have a material adverse impact on its results of operations, financial 
condition, and liquidity.  Additionally, if NS does not have sufficient capital to acquire new technology or if it is 
unable to implement new technology, NS may suffer a competitive disadvantage within the rail industry and with 
companies providing other modes of transportation service, which could have a material adverse effect on its 
financial position, results of operations or liquidity in a particular year or quarter. 

The vast majority of NS employees belong to labor unions, and labor agreements, strikes, or work 
stoppages could adversely affect its operations.  Approximately 26,000, or about 85%, of NS railroad 

K12 

  
 
  
  
 
  
 
employees are covered by collective bargaining agreements with various labor unions.  If unionized workers 
were to engage in a strike, work stoppage, or other slowdown, NS could experience a significant disruption of 
its operations.  Additionally, future national labor agreements, or renegotiation of labor agreements or 
provisions of labor agreements, could significantly increase NS’ costs for healthcare, wages, and other benefits.  
Any of these factors could have a material adverse impact on NS’ financial position, results of operations or 
liquidity in a particular year or quarter.  

NS may be subject to various claims and lawsuits that could result in significant expenditures.  The nature 
of NS’ business exposes it to the potential for various claims and litigation related to labor and employment, 
personal injury, freight loss and other property damage, and other matters.  Job-related personal injury and 
occupational claims are subject to the Federal Employers’ Liability Act (FELA), which is applicable only to 
railroads.  FELA’s fault-based tort system produces results that are unpredictable and inconsistent as compared 
with a no-fault worker’s compensation system.  The variability inherent in this system could result in actual costs 
being very different from the liability recorded.  

Any material changes to current litigation trends or a catastrophic rail accident involving any or all of freight 
loss or property damage, personal injury, and environmental liability could have a material adverse effect on 
NS’ operating results, financial condition, and liquidity to the extent not covered by insurance.  NS has obtained 
insurance for potential losses for third-party liability and first-party property damages.  Specified levels of risk 
are retained on a self-insurance basis (currently up to $25 million per occurrence for bodily injury and property 
damage to third parties and $25 million per occurrence for property owned by NS or in its care, custody or 
control).  Insurance is available from a limited number of insurers and may not continue to be available or, if 
available, may not be obtainable on terms acceptable to NS.   

Severe weather could result in significant business interruptions and expenditures.  Severe weather 
conditions and other natural phenomena, including hurricanes and floods, may cause significant business 
interruptions and result in increased costs, increased liabilities, and decreased revenues, which could have an 
adverse effect on NS’ financial position, results of operations or liquidity in a particular year or quarter. 

Unpredictability of demand for rail services resulting in the unavailability of qualified personnel could 
adversely affect NS’ operational efficiency and ability to meet demand.  Workforce demographics, training 
requirements, and the availability of qualified personnel, particularly engineers and trainmen, could each have a 
negative impact on NS’ ability to meet demand for rail service. Unpredictable increases in demand for rail 
services may exacerbate such risks, which could have a negative impact on NS’ operational efficiency and 
otherwise have a material adverse effect on its financial position, results of operations or liquidity in a particular 
year or quarter. 

NS may be affected by supply constraints resulting from disruptions in the fuel markets or the nature of 
some of its supplier markets.  NS consumes over 500 million gallons of diesel fuel each year.  Fuel availability 
could be affected by any limitation in the fuel supply or by any imposition of mandatory allocation or rationing 
regulations.  If a severe fuel supply shortage arose from production curtailments, disruption of oil imports, 
disruption of domestic refinery production, damage to refinery or pipeline infrastructure, political unrest, war or 
otherwise, NS’ financial position, results of operations or liquidity in a particular year or quarter could be affected.  
Also, such an event would impact NS as well as its customers and other transportation companies.   

Due to the capital intensive nature and industry-specific requirements of the rail industry, there are high barriers 
of entry for potential new suppliers of core railroad items, such as locomotives and rolling stock equipment.  
Additionally, NS competes with other industries for available capacity and raw materials used in the production of 
certain track materials, such as rail and ties.  Changes in the competitive landscapes of these limited-supplier 
markets could result in increased prices or material shortages that could materially affect NS’ financial position, 
results of operations or liquidity in a particular year or quarter.

Item 1B.  Unresolved Staff Comments. 

NS has no unresolved SEC staff comments. 

Item 3.  Legal Proceedings. 

On Oct. 19, 2006, the Pennsylvania Department of Environmental Protection (PDEP) issued an assessment of 
civil penalties against NS and filed a complaint for civil penalties with the Pennsylvania Environmental Hearing 
Board (EHB) requesting that the EHB impose civil penalties upon NS for alleged violations of state 
environmental laws and regulations resulting from a discharge of sodium hydroxide which occurred as a result of 
the derailment of a NS train in Norwich Township, Pennsylvania, on June 30, 2006.  The PDEP’s actions seek to 
impose combined penalties of $8,890,000 for alleged past violations and $46,420 per day for alleged ongoing 
violations of state environmental laws and regulations.  NS believes that the monetary penalties sought by the 
PDEP are excessive.  Accordingly, NS intends to vigorously defend the action and has appealed the fines to the 
EHB.  In addition, NS expects the Pennsylvania Fish and Boat Commission to impose a monetary penalty on NS 
for damages alleged to have been caused by this accident.  NS does not believe that the outcome of these 
proceedings will have a material effect on its financial position, results of operations, or liquidity. 

Item 4.  Submission of Matters to a Vote of Security Holders. 

There were no matters submitted to a vote of security holders during the fourth quarter of 2006.

2005 provision for income taxes includes a $96 million benefit related to the reduction of NS’ deferred income 
tax liabilities resulting from tax legislation enacted by Ohio.  This benefit increased net income by $96 million, 
or 23 cents per diluted share. 

2004 other income – net includes a $40 million net gain from the Conrail Corporate Reorganization.  This gain 
increased net income by $40 million or 10 cents per diluted share. 

2003 operating expenses include a $107 million charge for a voluntary separation program.  Other income – 
net includes an $84 million charge to recognize the impaired value of certain telecommunications assets.  
These charges reduced net income by $119 million, or 30 cents per diluted share. 

NS sold all the common stock of its motor carrier subsidiary, North American Van Lines, Inc. in 1998.  Results 
in 2003 include an additional after-tax gain of $10 million, or 3 cents per diluted share, resulting from 
resolution of tax issues related to the transaction. 

Net income in 2003 reflects two accounting changes, the cumulative effect of which increased net income by 
$114 million, or 29 cents per diluted share:  a change in accounting for the cost to remove railroad crossties, 
which increased net income by $110 million, and a change in accounting related to a special-purpose entity 
that leases certain locomotives to NS, which increased net income by $4 million. 

Excludes notes payable to Conrail of $716 million in 2003 and $513 million in 2002.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results of Operations. 

Norfolk Southern Corporation and Subsidiaries 
Management's Discussion and Analysis of 
Financial Condition and Results of Operations 

The following discussion and analysis should be read in conjunction with the Consolidated Financial Statements 
and Notes and the Selected Financial Data. 

OVERVIEW 

NS’ 2006 results reflect substantial increases in revenues (up $880 million, or 10%) resulting primarily from 
higher pricing, including increased fuel surcharges.  Traffic volume in 2006 rose modestly as increases in the first 
half of the year were largely offset by declines in the second half, particularly during the fourth quarter.  
Operating expenses rose 7%, resulting in a 21% improvement in income from railway operations and a lower 
operating ratio (a measure of the amount of operating revenues consumed by operation expenses) of 72.8% 
compared with 75.2% in 2005. 

Higher operating income for the year translated into increased cash flows, which, combined with substantial 
proceeds from employee stock option exercises, were used to fund increased capital expenditures, purchase and 
retire common stock, increase dividends and pay maturing debt.  At Dec. 31, 2006, the cash and short-term 
investment balance was $918 million.  Looking ahead, NS expects revenue increases to continue but at a more 
moderate pace, reflecting lower volume growth and comparison with a strong 2006.  NS plans to continue its 
focus on improving service levels and maintaining a market-based approach to pricing.  Approximately one-half 
of NS’ revenue base is subject to renegotiation or repricing in 2007. 

During 2006, NS purchased and retired 21.8 million shares of common stock at a total cost of $964 million under 
the share repurchase program approved by the Board of Directors on Nov. 22, 2005.  Under the program, the Board 
has authorized the repurchase of up to 50 million shares of NS common stock through Dec. 31, 2015. 

SUMMARIZED RESULTS OF OPERATIONS 

2006 Compared with 2005 

Net income in 2006 was $1.5 billion, or $3.57 per diluted share, up $200 million, or 16%, compared with 
$1.3 billion, or $3.11 per diluted share, in 2005.  The increase in net income was primarily due to higher income 
from railway operations, offset in part by the absence of the $96 million income tax benefit recorded in 2005 
because of Ohio tax law changes (see Note 3).  Railway operating revenues increased $880 million, reflecting 
higher rates, including fuel surcharges that accounted for about 40% of the increase and modestly higher traffic 
volume.  Railway operating expenses rose $440 million, or 7%, principally due to higher diesel fuel prices and 
increased compensation and benefit costs. 

2005 Compared with 2004 

Net income in 2005 was $1.3 billion, or $3.11 per diluted share, up $371 million, or 41%, compared with 
$910 million, or $2.28 per diluted share, in 2004.  Results in 2005 reflected a $96 million second quarter income 
tax benefit related to Ohio tax law changes (see Note 3), while results in 2004 included a $40 million net gain 
related to the Conrail Corporate Reorganization (see Note 4).  The remaining $315 million increase in net income 
was primarily due to higher income from railway operations.  Railway operating revenues increased $1.2 billion, 
reflecting higher rates (including the favorable effects of the coal rate cases settled in the second quarter – see 

K20 

  
  
  
  
  
 
 
 
 
 
  
 
 
 
below), fuel surcharges and increased traffic volume.  Railway operating expenses rose $800 million, or 14%, 
principally due to higher diesel fuel prices, increased volume-related expenses and casualty claims costs.

Revenues increased $880 million, or 10%, in 2006 and $1.2 billion, or 17%, in 2005.  As shown in the following 
table, both revenue improvements were the result of increased average revenues per unit, including fuel 
surcharges, and, to a lesser extent in 2006 than for 2005, higher traffic volumes.

Both comparisons reflect large increases in average revenue per unit, a result of higher rates and increased fuel 
surcharges.  All market groups collected significant fuel surcharges, which accounted for approximately 40% of 
the 2006 increase in revenues and about one-third of the 2005 increase.  At year-end 2006, fuel surcharge 
provisions covered approximately 91% of total revenues compared with about 85% at the end of 2005.  Traffic 
volume increased 1% in 2006, principally due to higher intermodal and metals/construction shipments.  In 
2005, traffic volume rose 4%, reflecting a 9% increase in intermodal shipments.  The favorable revenue per 
unit/mix variance in 2005 included an unfavorable mix component reflecting the 9% rise in intermodal traffic, 
which has a lower average revenue per unit. 

On April 24, 2006, NS announced that it was revising its fuel surcharge program for non-intermodal traffic 
originating and moving on NS-issued tariffs and public quotes issued on or after July 1, 2006.  While the 
mechanics of the new fuel surcharge are generally the same as the previous fuel surcharge, the trigger price was

raised from $23 to $64 per barrel of West Texas Intermediate (WTI) Crude Oil and the percentage by which the 
line haul rate is increased when oil exceeds the trigger price was decreased from 0.4% to 0.3% for each dollar or 
portion thereof in excess of the trigger price.  Tariff prices and public quotes have been adjusted to reflect this 
change.  The fuel surcharge is based on the monthly average price of WTI in the second calendar month prior to 
the month in which the fuel surcharge is applied.  Application of the new fuel surcharge across tariff and public 
quotes as well as contracts now approximates 15% of NS’ total revenue base. 

On January 26, 2007, the Surface Transportation Board (STB) issued a decision that the type of fuel surcharge 
imposed by NS and most other large railroads – a fuel surcharge based on a percentage of line haul revenue – 
would no longer be permitted for regulated traffic that moves under public (tariff) rates.  The STB gave the 
railroads a 90-day transition period to adjust their fuel surcharge programs.  NS does not expect that 
compliance with these new regulations will have a material effect on its financial condition, results of 
operations or liquidity. 

COAL revenues increased $215 million, or 10%, compared with 2005, which reflected higher average 
revenue per unit and slightly higher traffic volume.  Coal average revenue per unit was up 9% compared with 
2005, reflecting increased fuel surcharges and higher rates, tempered by the absence of the $55 million benefit 
from the coal rate settlements in the second quarter of 2005 (see below).  Coal represented 25% of NS’ 
revenues in 2006, and 79% of shipments handled originated on NS’ lines.  Traffic volumes rose 1% primarily 
because of increased shipments of utility coal, domestic metallurgical coal and coke that offset lower export 
and iron ore shipments.   

NS is currently involved in litigation with Virginia Electric and Power Company/Old Dominion Electric 
Cooperative (Virginia Power) regarding rate adjustment provisions in a transportation contract between them.  
During the third quarter of 2006, a court order was entered in favor of NS, and in the fourth quarter Virginia 
Power filed a petition with the Virginia Supreme Court appealing this order.  Future developments and the 
ultimate resolution of this matter could result in NS recognizing additional revenues related to this dispute, which 
could have a favorable impact on results of operations in a particular year or quarter. 

In 2005, coal revenues increased $387 million, or 22%, compared with 2004, reflecting higher average revenue 
per unit and increased traffic volume.  Coal average revenue per unit was up 19% compared with 2004, reflecting 
higher rates, the favorable effects of fuel surcharges, longer-haul business and the rate cases settled in the second 
quarter (see below).  Coal represented 25% of NS’ revenues in 2005, and 83% of shipments handled originated on 
NS’ lines.  Traffic volumes rose 3% primarily because of increased shipments of utility coal that offset lower 
export and domestic metallurgical coal, coke and iron ore shipments. 

During the second quarter of 2005, NS entered into settlement agreements with two utility customers that resolved 
their rail transportation rate cases before the STB.  In 2002, these customers each filed rate reasonableness 
complaints with the STB.  In October 2004, the STB found NS’ rates to be reasonable in both cases.  As a result 
of the settlement of these cases, NS recognized $55 million of additional coal revenue in 2005 related to the 
period in dispute.

Utility coal tonnage increased 4%, compared with 2005, reflecting the rebuilding of stockpiles by customers, 
more shipments from the Powder River Basin in the West and higher shipments of import coal through 
Charleston, SC. 

In 2005, utility coal tonnage increased 6% compared to 2004, in response to increased coal-fired generation to meet 
the heavier electricity demand of a strong economy, limited nuclear power generation capacity, higher natural gas 
prices and utility coal stockpiles which were below target levels across NS’ service area.  Supply constraints 
dampened shipments while the increased demand for Eastern U.S. coal prompted some customers to shift to coal 
from non-traditional sources in Wyoming and Colorado and imported coal.  Appalachian coal production increased 
modestly and Western coal production was up 2% in 2005. 

While natural gas prices are expected to remain higher in 2007, demand for utility coal could be tempered by 
persistent mild winter weather in the East and above average stockpiles.  Additionally, in November 2006, 
Virginia Power announced it intends to switch from domestic coal to imported coal for its Chesapeake, Virginia, 
Energy Center.  Since NS would not transport the imported coal, this change would result in the loss of 
approximately 1.6 million tons annually.   

A number of evolving environmental issues could affect the utility coal market.  These include potential regional 
programs aimed at capping and reducing power plant CO2 emissions, and ongoing efforts at addressing climate 
change.  In response to changes in environmental regulations, certain utilities have begun adding or are planning 
to add emissions control technologies to their electric generating units, allowing them to utilize their existing coal-
fired power plants. 

Domestic metallurgical coal, coke and iron ore tonnage increased 4% in 2006 compared with 2005.  The 
increase was driven by higher domestic metallurgical coal and coke shipments in the first half of the year in 
response to steel-making demand, which more than offset a decline in iron ore volume caused by the shutdown of 
a blast furnace at a major customer location. 

For 2005, domestic metallurgical coal, coke and iron ore tonnage was down 3%, compared with 2004.  Declines 
in domestic coke and iron ore volumes, principally due to the idling of a major steel blast furnace, were partially 
offset by an 8% increase in metallurgical coal. 

Demand for domestic metallurgical coal and coke is expected to decline slightly with a softening in the steel 
industry in 2007, whereas new business is expected to modestly increase iron ore shipments.   

Export coal tonnage decreased 15% in 2006 compared to 2005, reflecting weaker demand for U.S. coal as 
Europe and Asia continued to increase purchases from other countries.  Baltimore volume was down 
approximately 13,500 cars, or 37%, and Norfolk volume declined by approximately 3,000 cars, or 3%. 

In 2005, export coal tonnage decreased 12% compared to 2004, due to both coal supply constraints and a weak 
European steel market.  Volume through Norfolk and Baltimore decreased.  Norfolk was down approximately 
16,000 carloads, or 14%, and Baltimore was down approximately 2,000 carloads, or 6%.  U.S. exports in 2005 were 
constrained by several factors:  (1) the tight coal supply from Eastern coal mines caused primarily by the sporadic 
closure of a major coal mine, (2) the idling of production by European steel manufacturers in order to manage 
finished goods inventory, and (3) the abundant supply of Chinese coke on the world market lowering the price and 
making it more economical to buy coke rather than import metallurgical coal from the U.S. and convert it. 

Export coal tonnage for 2007 is expected to weaken as higher mining costs offset potential gains from favorable 
ocean freight rates from the U.S. versus Australia. 

K23 

 
 
 
 
 
 
 
 
 
 
Other coal tonnage (principally steam coal shipped to industrial plants) decreased 3% versus 2005, primarily due 
to plant closures and mine production problems.  In 2005, other coal tonnage decreased 3% versus 2004, 
primarily due to the diversion of coal to the utility market. 

GENERAL MERCHANDISE revenues increased $520 million, or 11%, in 2006 compared with 2005, as all 
market groups posted higher average revenue per unit driven by increased rates and fuel surcharges.  Traffic 
volume declined slightly as improved metals and construction and agriculture volumes were offset by declines in 
the other business groups.  In 2005, general merchandise revenues increased 13% due to higher average rates and 
fuel surcharges.  Traffic volume was up modestly in 2005 compared with 2004 as decreases in automotive and 
chemicals traffic partially offset increases in other business groups.   

Metals and construction revenue increased 19% and traffic volume increased 5% in 2006 compared with 2005 
as declines in the fourth quarter were offset by higher volumes through the rest of the year.  Revenue per unit rose 
14% because of increased rates and fuel surcharges.  The increase in traffic volume was driven primarily by 
higher import slab business to NS-served steel mills, more scrap metal shipments and higher sand, gravel and 
cement traffic for commercial and highway construction projects. 

In 2005, metals and construction revenue increased 20% and traffic volume increased 2% compared with 2004.  
Revenue per unit rose 17% because of higher rates and fuel surcharges.  The volume improvements were due 
primarily to continued strength at NS-served integrated and electric arc mills and higher aluminum product 
shipments, which were partially offset by lower scrap metal carloads.  Construction traffic volume benefited from 
increased residential, commercial and highway construction. 

Metals and construction volume is expected to be tempered in the first quarter of 2007, reflecting a softening in 
domestic steel production affecting iron and steel shipments, with improving conditions expected in the second 
half of the year.  Aggregate and cement shipments are expected to increase driven by highway projects and new 
stone terminals locating on NS’ lines. 

Chemicals revenue increased 10%, despite a 4% drop in traffic volume, reflecting increased rates and fuel 
surcharges.  Petroleum, industrial and plastics traffic volumes were down as a result of lower inventories 
arising from post-Katrina conditions, the closure of several plants on NS lines and the weaker housing and 
automotive markets. 

In 2005, chemicals revenues increased 13%, reflecting higher prices and fuel surcharges, while traffic volume 
was down slightly as a result of production curtailment in the Gulf Coast region and as compared with a strong 
2004.  Volume increases for plastic and petroleum products were offset by decreases in industrial and 
miscellaneous chemicals. 

Chemical volume is expected to improve in 2007, supported by new and expanded business as the year 
progresses.  However, volume could be adversely affected by the price of natural gas and crude oil, which 
accounts for more than 50% of the cost of many chemical products and presents a significant competitive 
challenge that could cause domestic chemical producers to move production overseas. 

Agriculture, consumer products and government revenue increased 19% and traffic volume increased 4% in 
2006 compared with 2005.  Average revenue per unit rose 15%, a result of higher rates and fuel surcharges.  
Traffic volume growth resulted from increased ethanol, military and corn shipments.  Military traffic growth was 
primarily due to the continued support of military operations in Iraq. 

In 2005, agriculture, consumer products and government revenue increased 16% and traffic volume increased 2% 
compared with 2004.  Average revenue per unit rose 14%, a result of higher rates and fuel surcharges.  Traffic 
growth resulted from sweeteners, government traffic and fertilizer.  Government traffic growth was primarily due 
to the support of military operations in Iraq as well as shipments of temporary housing to hurricane-damaged 

K24 

 
 
 
 
 
 
 
 
 
areas.  Ethanol traffic increased 38% due to higher shipments from current customers in addition to new business 
in Georgia and South Carolina.   

Agriculture volume is expected to continue to grow in 2007, benefiting from increasing demand for ethanol as a 
replacement for MTBE which was banned by the Federal Government as a fuel additive.  However, declines in 
consumer products and government volumes are expected to offset this growth. 

Automotive revenues declined 2% in 2006 compared with 2005 as lower volumes offset increased average 
revenues per unit, including fuel surcharges.  Volume decreased 9% primarily due to substantial production cuts 
at Ford, General Motors and Daimler-Chrysler assembly plants, including two NS-served plant closures at Ford 
and one at General Motors during 2006.  Ford and General Motors combined operate 15 of 29 assembly plants 
served by NS.  Reduced production at Honda and BMW also contributed to the volume decrease. 

In 2005, automotive revenues rose 5%, compared with 2004, the result of an 8% increase in average revenue per 
unit that reflected pricing improvements and higher fuel surcharges.  In contrast, traffic volume decreased 3% 
primarily due to reduced production at Ford and General Motors, with General Motors closing NS-served 
assembly plants in Michigan, Maryland and New Jersey.  These reductions were partially offset by increased 
production at Honda, Mercedes-Benz and Toyota. 

For 2007, NS expects automotive revenues to continue to decline as a result of automotive production cutbacks.  
Decreases by U.S. automotive manufacturers are expected to be partially offset by higher domestic production by 
foreign manufacturers. 

Paper, clay and forest products revenue increased 11% in 2006 compared with 2005 due to higher average 
revenues per unit, including fuel surcharges, despite a 1% decrease in traffic volume.  Higher solid waste and 
debris traffic, and growth in traffic from the import of printing paper, partially offset reduced pulp and pulp 
board shipments. 

In 2005, paper, clay and forest products revenue increased 16% and traffic volume increased 2% compared with 
2004.  Average revenue per unit rose 13% due to higher rates and fuel surcharges.  Pulp board, printing paper, 
newsprint and woodchip produced volume gains despite consolidations within the industry and mill shutdowns. 

In 2007, paper, clay and forest product revenues are expected to be up slightly and benefit from continued growth 
in waste and debris transportation. 

INTERMODAL revenues increased $145 million, or 8%, compared with 2005, largely because of higher fuel 
surcharges, increased rates and improved traffic volume.  Traffic volume for the year rose 3% notwithstanding a 
3% decline in the fourth quarter.  International traffic volume rose 9% reflecting growth in imported goods from 
Asia and exported goods through NS-served East Coast ports, as well as West Coast ports.  Truckload volume 
increased 8% reflecting continued expansion of business with traditional truckload companies.  Triple Crown 
Services Company, a service with rail-to-highway trailers, had flat volume compared with 2005 as higher 
consumer product shipments were offset by weaker automotive-related shipments.  Domestic intermodal 
marketing companies (IMC) volume declined 9% reflecting declines in the housing, construction and automotive 
markets.  Premium business, which includes parcel and LTL (less-than-truckload) carriers, was down 3% 
reflecting lower LTL shipper traffic that offset modest gains in parcel shipments.  Intermodal revenue per unit 
increased 4%, principally a result of higher fuel surcharges as well as increased rates and longer-haul international 
traffic, which was offset in part by the ongoing shift of shipments from higher revenue per unit, rail-provided 
assets (trailers and containers) to lower revenue per unit shipments in shipper-provided equipment. 

In 2005, intermodal revenues increased $289 million, or 19% compared with 2004, reflecting improved traffic 
volume, higher fuel surcharges, and increased rates.  Despite moderated growth in domestic business, traffic 
volume increased 9% reflecting strength in the international, truckload and Triple Crown Services lines of 

K25 

 
 
 
 
 
 
  
 
 
business.  International traffic volume grew by 16% reflecting strength in U.S. consumer markets and growth in 
the movement of import and export goods through NS-served East Coast ports, as well as West Coast ports.  
Truckload volume increased 10% compared with 2004, reflecting additional business with traditional truckload 
companies.  Premium business grew 6% due primarily to new business in the Northern region.  Triple Crown 
Services volume grew 6% reflecting expanded geographic coverage and increased trailer fleet size to meet higher 
demand.  Domestic volume decreased 3% compared with 2004, principally due to the continued reduction in 
transloading of West Coast international freight into domestic containers.  Intermodal revenue per unit increased 
9%, a result of fuel surcharges and rate increases.   

In 2007, NS expects moderate growth in its intermodal markets, with continued strength in the international 
markets.  Future growth may, however, be tempered by economic conditions in the U.S. 

Railway Operating Expenses 

Railway operating expenses in 2006 were $6.9 billion, up $440 million, or 7%, compared to 2005, which were up 
$800 million compared to 2004.  The 2006 increase was principally due to higher diesel fuel prices and increased 
compensation and benefits.  The increase in 2005 was principally due to a sharp rise in the price of diesel fuel, 
volume-related expense increases, more maintenance activities and higher casualty costs.  Carloads rose 1% in 
2006 compared to 2005 and 4% in 2005 compared to 2004. 

The railway operating ratio, which measures the percentage of railway operating revenues consumed by railway 
operating expenses, improved to 72.8% in 2006, compared with 75.2% in 2005 and 76.7% in 2004.

Compensation and benefits, which represents nearly 40% of total railway operating expenses, increased 
$144 million, or 6%, compared with 2005, and increased $221 million in 2005, or 10%, compared with 2004.  
Expenses in 2006 included the effect of the implementation of Statement of Accounting Standards No. 123(R) 
“Share-Based Payment,” which increased stock-based compensation expense by $27 million.  Most of the 
increase was reflected in the first quarter which included the effect of accelerated recognition of costs related to 
grants to retirement-eligible employees.  This up front recognition of costs will occur in the first quarter of 2007 
and is expected to be somewhat higher reflecting a higher proportion of retirement eligible grantees.  The 
remaining increase was attributable to increased salaries and wages (up $44 million), higher health and welfare 
benefit costs (up $29 million), higher payroll taxes (up $17 million), retirement and waiver agreements entered 
into in the first quarter (up $13 million) and the cost of the regular stock-based grant to the former chief executive 
officer who retired in the first quarter ($11 million).

NS employment averaged 30,541 in 2006 compared with 30,294 in 2005 and 28,475 in 2004.  The increased 
number of employees has come almost exclusively in operating department personnel to meet the increased 
volume and service needs, as well as expected retirements.  NS continues to hire and train additional workers in 
order to meet the requirements of forecasted volumes in light of the demographics of its work force. 

The increase in compensation and benefits for 2005 reflected increased hours for train operations, including 
trainees, and equipment maintenance (up $70 million); increased wage rates (up $46 million); increased 
pension, postretirement and health and welfare benefit costs (up $43 million); higher stock-based compensation 
(up $22 million); and higher payroll taxes (up $12 million). 

The Railroad Retirement and Survivors’ Improvement Act, which took effect Jan. 1, 2002, allows for 
investment of Tier II assets in a diversified portfolio through the National Railroad Retirement Investment 
Trust.  The law also provides a mechanism for automatic adjustment of Tier II payroll taxes should the trust 
assets fall below a four-year reserve or exceed a six-year reserve.  As a result, the employers’ portion of Tier II 
retirement payroll taxes has been reduced from 13.1% in 2004 to 12.6% in 2005 and 2006, and to 12.1% for 
2007.   However, these savings are expected to continue to be substantially offset by higher payroll taxes on 
increased wages and a higher wage base. 

Materials, services and rents includes costs related to items used for the maintenance of railroad lines, structures 
and equipment; the costs of services purchased from outside contractors, including the net costs of operating joint 
(or leased) facilities with other railroads; and the net cost of equipment rentals.  This category of expenses 
increased $86 million, or 5%, in 2006 compared to 2005, and increased 13% in 2005 compared to 2004.  For 
2006, materials expense was up $39 million due to increased maintenance activities, purchased services was up 
$39 million reflecting increased intermodal traffic volume and equipment rents rose $8 million. 

The increase in 2005 reflected higher volume-related purchased services (up $82 million) and higher maintenance 
expense (up $74 million).  Equipment rents rose $28 million, reflecting higher traffic volume as well as leases 
from the Conrail Corporate Reorganization (see Note 4). 

Locomotive and freight car repair costs increased in 2006 and in 2005, due to more maintenance activity related 
to higher usage from increased traffic volumes coupled with the age of the fleet.  This level of expense is 
expected to continue and may increase depending on traffic volumes. 

Equipment rents, which includes the cost to NS of using equipment (mostly freight cars) owned by other railroads 
or private owners less the rent paid to NS for the use of its equipment, rose 2% in 2006 and increased 11% in 
2005.  The increase in 2006 was principally due to a reduction in rents received on automotive equipment as a 
result of decreased shipments.  The increase in 2005 was principally due to additional lease expense for a full year 
from the Conrail Corporate Reorganization and increased volume-related intermodal shipments. 

Conrail rents and services decreased $3 million, or 2%, in 2006 compared to 2005, and decreased 60% in 
2005 compared to 2004.  For 2006 and 2005 this item includes amounts due to Conrail for operation of the 
Shared Assets Areas.  Before the Conrail Corporate Reorganization in 2004 this item included amounts due to 
PRR for use of its operating properties and equipment, NS’ equity in Conrail’s net earnings and the additional 
amortization related to the difference between NS’ investment in Conrail and its underlying equity (see Note 4).  
The decline in 2005 was primarily driven by the Conrail Corporate Reorganization, which resulted in the 
consolidated reporting of individual components of Conrail equity earnings, principally depreciation, 
equipment rents and interest expense (see Note 4).  NS’ share of equity earnings after the Conrail Corporate 
Reorganization is a component of “Other income-net” (see Note 2). 

Depreciation expense decreased $36 million, or 5%, in 2006 compared with 2005, reflecting the results of an 
equipment depreciation study from an independent firm of engineers and an analysis of the assets received in 
the Conrail Corporation Reorganization completed in 2006.  Depreciation expense increased 29% in 2005 

K27 

 
 
 
 
 
 
 
 
compared to 2004 primarily a result of the Conrail Corporate Reorganization (see Note 4).  In addition, 
substantial capital investments and improvements resulted in higher depreciation expense. 

Diesel fuel expense increased $250 million, or 34%, in 2006 compared with 2005 and increased 62% in 2005 
compared with 2004.  Diesel fuel expense is recorded net of hedge benefits, although there have been no such 
benefits since May 2006 when the program wound down (see “Market Risks and Hedging Activities,” below 
and Note 16).  Expense in 2006 included hedge benefits of $20 million compared with benefits of $148 million 
in 2005, and $140 million in 2004, and reflected a 13% rise in the average price per gallon with a 1% increase 
in consumption.  The increase in 2005 reflected a 43% rise in the average price per gallon and a 2% increase in 
consumption. 

Legislation enacted in the first quarter of 2005 repealed the 4.3 cents per gallon excise tax on railroad diesel fuel for 
2007, with the following phased reductions in 2005 and 2006: 1 cent per gallon from Jan. 1, 2005 through June 30, 
2005; 2 cents per gallon from July 1, 2005 through Dec. 31, 2006; and by the full 4.3 cents thereafter.  NS consumes 
about 520 million gallons of diesel fuel per year. 

Casualties and other claims expenses (including the estimates of costs related to personal injury, property 
damage and environmental matters) decreased $4 million, or 2%, in 2006 compared to 2005 and increased 48% in 
2005 compared to 2004.  The decrease in 2006 reflected the absence of $38 million of costs associated with a 
derailment in Graniteville, South Carolina (see discussion below), and an unfavorable jury verdict in an employee 
injury case, partially offset by higher expenses arising from derailments and insurance costs.  The increase in 
2005 was attributable to the costs associated with the Graniteville derailment, $16 million for an unfavorable jury 
verdict rendered in an employee injury case, $9 million of higher insurance costs, and $4 million for the portion of 
the $12.5 million self-insured retention related to Hurricane Katrina expenses. 

On Jan. 6, 2005, a collision in Graniteville, South Carolina, between two NS trains caused the release of chlorine 
gas from a ruptured tank car.  NS’ liability related to this accident includes a current and long-term portion which 
represents NS’ best estimate based on current facts and circumstances.  The estimate includes amounts related to 
business property damage and other economic losses, personal injury and individual property damage claims as 
well as third-party response costs.  NS’ commercial insurance policies are expected to cover substantially all 
expenses related to this derailment above NS’ self-insured retention, including NS’ response costs and legal fees.  
Accordingly, the Consolidated Balance Sheets reflect a current and long-term receivable for estimated recoveries 
from NS’ insurance carriers.  The expense recorded in 2005 represents NS’ retention under its insurance policies 
and other uninsured costs.  While it is reasonable to expect that the liability for covered losses could differ from 
the amount recorded, such a change would be offset by a corresponding change in the insurance receivable.  As a 
result, NS does not believe that it is reasonably likely that its net loss (the difference between the liability and 
future recoveries) will be materially different than the loss recorded in 2005.  NS expects at this time that 
insurance coverage is adequate to cover potential claims and settlements above its self-insurance retention.  

During the third quarter of 2005, NS’ operations were adversely affected by Hurricane Katrina, and to a lesser 
extent, Hurricane Rita, both of which struck the Gulf Coast.  NS sustained damage to its facilities in the region as a 
result of Hurricane Katrina but restored rail freight service into and around New Orleans in a relatively short period 
of time.  The damage sustained to NS facilities as a result of Hurricane Katrina did not materially impact NS’ 
financial condition or results of operations and is covered by insurance above the self-insurance retention limit.   

The largest component of casualties and other claims expense is personal injury costs.  Cases involving 
occupational injuries comprised about two-thirds of total employee injury cases resolved and about one-third of 
total payments made.  With its long-established commitment to safety, NS continues to work actively to 
eliminate all employee injuries and to reduce the associated costs.  With respect to occupational injuries, which 
are not caused by a specific accident or event, but result from a claimed exposure over time, the benefits of any 
existing safety initiatives may not be realized immediately.  These types of claims are being asserted by former 
or retired employees, some of whom have not been actively employed in the rail industry for decades. 

K28 

 
 
 
 
 
 
The rail industry remains uniquely susceptible to litigation involving job-related accidental injury and 
occupational claims because of the Federal Employers' Liability Act (FELA), which is applicable only to 
railroads.  FELA’s fault-based system, which covers employee claims for job-related injuries, produces results 
that are unpredictable and inconsistent as compared with a no-fault workers' compensation system. 

NS maintains substantial amounts of insurance for potential third-party liability and property damage claims.  It 
also retains reasonable levels of risk through self-insurance (see Note 17).  NS expects insurance costs to be 
slightly higher in 2007. 

Other expenses increased $3 million, or 1%, in 2006 compared to 2005, and increased $34 million, or 15%, in 
2005 compared to 2004.  The increase in 2006 was primarily due to higher employee travel and relocation costs 
offset in part by lower property taxes.  The increase in 2005 reflected higher property and sales and use taxes. 

Other Income – Net 

Other income – net was $149 million in 2006 and $74 million in 2005 (see Note 2).  Results in 2006 reflected 
lower expense associated with tax credit investments primarily due to synthetic fuel related investments (see 
discussion under heading “Income Taxes”), greater interest income, and higher returns from corporate-owned life 
insurance, that were partially offset by lower equity in Conrail earnings.   

In 2005, other income – net decreased by $2 million which reflected the absence of the $40 million gain recognized 
in 2004 for the Conrail Corporate Reorganization.  The results in 2005 also reflected:  (1) higher interest income, 
(2) equity in earnings of Conrail subsequent to the Conrail Corporate Reorganization, (3) additional coal royalties 
(up $12 million), and (4) lower interest accruals related to tax liabilities (down $9 million).  These income 
improvements were partially offset by more expense associated with tax credit investments. 

Income Taxes 

Income tax expense in 2006 was $749 million for an effective rate of 34%, compared with effective rates of 25% 
in 2005 and 29% in 2004.  The increase in the rate for 2006 was largely the result of the absence of an Ohio tax 
law change which lowered the effective rate in 2005 as well as fewer tax credits from synthetic fuel related 
investments (see below).  The 2005 effective rate benefited from a $96 million reduction in deferred taxes 
resulting from the Ohio tax legislation, which lowered the rate by six percentage points (see Note 3).   

NS’ consolidated federal income tax returns for 2004 and 2005 are being audited by the Internal Revenue Service 
(IRS).  The IRS completed its examination of the 2002 and 2003 consolidated federal income tax returns during 
the third quarter of 2006 and NS has appealed certain adjustments proposed by the IRS.  The results of the 
examination had a negligible effect on the effective tax rate.   

NS’ synthetic fuel tax credits are subject to reduction if the Reference Price of a barrel of oil for the year falls 
within an inflation-adjusted phase-out range specified by the tax code.  The Reference Price for a year is the 
annual average wellhead price per barrel of unregulated domestic crude oil as determined by the Secretary of 
the Treasury by April 1 of the following year.  In 2005, the phase-out range was $53.20 to $66.79, and the 
phase-out range is adjusted annually for inflation.  While NS cannot predict with certainty the Reference Price 
for the year, NS estimated a 35% phase-out of synthetic fuel credits in 2006 based on actual oil prices during 
the year.

Subject to the uncertainty associated with these tax credits, the effective tax rate in 2007 is expected to be 
comparable to that of 2006.  The tax credits generated by NS’ synthetic fuel related investments expire at the end 
of 2007 and, accordingly, the effective tax rate may increase thereafter.   

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES 

Cash provided by operating activities, NS' principal source of liquidity, was $2.2 billion in 2006, compared 
with $2.1 billion in 2005 and $1.7 billion in 2004.  The improvement in 2006 reflected the $440 million increase 
in income from railway operations offset in part by higher income tax payments.  The increase in 2005 reflected 
the $415 million increase in income from railway operations as well as the effects of the Conrail Corporate 
Reorganization (see below), offset in part by higher income tax payments, including a payment made upon 
settlement of a federal audit cycle. 

Prior to the August 2004 Conrail Corporate Reorganization (see Note 4), a significant portion of the payments 
made to PRR under the operating and lease agreements (which were included in “Conrail rents and services” and, 
therefore, were a use of cash in “Net cash provided by operating activities”), was borrowed back from a 
subsidiary of PRR under a note due in 2032 and, therefore, was a source of cash in “Proceeds from borrowings.”  
NS’ net cash flow from these borrowings amounted to $118 million in 2004.  This note was effectively 
extinguished by the reorganization in 2004.  Subsequent to the Conrail Corporate Reorganization, 2005 payments 
under “Conrail rents and services” declined, depreciation charges increased and those net borrowings were 
terminated.  Accordingly, NS’ cash provided by operating activities after the Conrail Corporate Reorganization 
has increased. 

NS had working capital of $307 million at Dec. 31, 2006, compared with working capital of $729 million at 
Dec. 31, 2005.  The reduction was largely due to share repurchases made in 2006 (see Note 13) and higher 
current maturities of long-term debt.  NS’ cash, cash equivalents and short-term investment balances totaled 
$918 million and $1.3 billion at Dec. 31, 2006 and 2005, respectively.

Off balance sheet arrangements consist of obligations related to operating leases, which are included in the

securitization program which expired in May 2005.   

Cash used for investing activities was $684 million in 2006, compared with $1.8 billion in 2005 and $1.2 billion 
in 2004.  The decrease in 2006 reflected higher proceeds from short-term investment sales, principally to fund 
share repurchases reflected in financing activities, offset in part by the $100 million investment in Meridian 
Speedway LLC (MSLLC) (see discussion below) and increased property additions.  The increase in 2005 was 
principally the result of larger purchases of short-term investments.   

Property additions account for most of the recurring spending in this category.  The following tables show capital 
spending (including capital leases) and track and equipment statistics for the past five years.

The higher average age of locomotives in 2006 reflects the retirement of two locomotives compared with 52 
retired in 2005. 

For 2007, NS has budgeted $1.34 billion for capital expenditures.  The anticipated spending includes 
$884 million for roadway projects, $401 million for equipment and $55 million for small projects and real 
estate.  In roadway projects, $610 million is for track and bridge program work, including $73 million in 
infrastructure investments for increased main line and terminal capacity.  Also included are projects for 
communications, signal and electrical systems, as well as projects for environmental and public improvements 
such as grade crossing separations and signal upgrades.  Other roadway projects include marketing and 
industrial development initiatives, including increasing track capacity and access to coal receivers and vehicle 
production and distribution facilities, and continuing investments in intermodal infrastructure.  Planned 
equipment spending of $401 million includes the purchase of 53 locomotives and upgrades to existing units, the 
purchase of 1,300 new higher capacity coal cars as part of a multi-year program to replace the existing coal car 
fleet, the purchase of 739 freight cars as their lease expires, improvements to multilevel automobile racks, and 
projects related to computers and information technology, including additional security and backup systems.  
NS expects to make all of its capital expenditures with internally generated funds. 

On May 1, 2006, NS and Kansas City Southern (KCS) formed a joint venture (MSLLC) pursuant to which NS 
intends to contribute $300 million in cash, substantially all of which will be used for capital improvements over 
a period of approximately three years, in exchange for a 30% interest in the joint venture.  At the formation of 
MSLLC, NS contributed $100 million and KCS contributed its 320 mile rail line between Meridian, 
Mississippi and Shreveport, Louisiana (the Meridian Speedway).  NS is recognizing its pro rata share of the 
joint venture’s earnings or loss as required under the equity method of accounting.  NS’ total investment in 
MSLLC is supported by the fair value of the rail line as well as intangible assets obtained through the 
transaction.  The transaction is expected to be modestly dilutive in the early years of the venture due to lost 
interest income on the cash contributed to the joint venture.  However, NS expects that the dilution from the 
lost interest income will be offset from additional traffic as the investment is made and improvements are 
completed.  The joint venture is expected to increase capacity and improve service over the Meridian Speedway 
into the Southeast. 

During the third quarter of 2006, NS and the states of Ohio, West Virginia and Virginia each entered into a 
Memorandum of Agreement with the Federal Highway Administration that governs the release of up to 
$95 million in federal funding and up to $11 million in state funding for the Heartland Corridor rail double-
stack clearance project.  NS expects to spend about $60 million over a five-year period in connection with this 
project.  The Heartland Corridor is a package of proposed clearance improvements and other facilities that will 
create a seamless high-capacity intermodal route across Virginia and West Virginia to Midwest markets. 

NS and other railroads have agreed to participate in the Chicago Region Environmental and Transportation 
Efficiency (CREATE) project in Chicago.  The intent of the proposed public-private partnership is to reduce rail 
and highway congestion and add freight and passenger capacity in the metropolitan Chicago area.  A portion of 
the public funding has been approved and the parties are working to develop a list of projects to be included in 
Phase I of the project.  Funding requirements will be determined by the selection of Phase I projects.  The 
railroads expect to complete Phase I over the next four years.

Cash used for financing activities was $1.3 billion in 2006, compared with $456 million in 2005 and 
$233 million in 2004.  Financing activity in 2006 included $964 million for the purchase and retirement of 
common stock as part of NS’ ongoing share repurchase program (see discussion below).  Financing activities for 
2006 also included $212 million of proceeds and $85 million of tax benefits from employee exercises of stock 
options (see Note 11).   

In 2005, financing activity included: (1) the issuance of $300 million aggregate principal amount of 6% unsecured 
notes due March 2105, and (2) the issuance of $717 million of unsecured notes ($350 million at 5.64% due 2029 
and $367 million at 5.59% due 2025) and payment of $218 million of premium in exchange for $717 million of 
previously issued unsecured notes ($350 million at 7.8% due 2027, $200 million at 7.25% due 2031, and 
$167 million at 9.0% due 2021) (see Note 7).  The $218 million cash premium payment is reflected as a reduction 
of debt in the Consolidated Balance Sheets and Statement of Cash Flows and will be amortized as additional 
interest expense over the terms of the new debt.  Financing activities in 2005 included $194 million in proceeds 
relating to employee exercises of stock options.  NS’ debt-to-total capitalization ratio was 40.7% at Dec. 31, 2006, 
and 42.8% at Dec. 31, 2005.   

In November 2005, NS’ Board of Directors authorized the repurchase of up to 50 million shares of NS common 
stock through Dec. 31, 2015.  The timing and volume of any purchases will be guided by management’s 
assessment of market conditions and other factors.  Near-term purchases under the program are expected to be 
made with internally generated cash; however, future funding sources could include proceeds from the sale of 
commercial paper notes or the issuance of long-term debt. 

NS currently has in place and available a $1 billion, five-year credit agreement that expires in 2009, which provides 
for borrowings at prevailing rates and includes financial covenants.  There were no amounts outstanding under this 
facility at Dec. 31, 2006, and NS is in compliance with all of the financial covenants.  NS also has in place a shelf 
registration statement on Form S-3 filed with the SEC in September 2004 with $700 million of available capacity 
(see Note 7).  On July 18, 2005, Standard & Poor’s (S&P) upgraded its ratings on NS’ unsecured debt from BBB to 
BBB+.  Moody’s rating remains at Baa1, comparable to S&P’s. 

APPLICATION OF CRITICAL ACCOUNTING ESTIMATES 

The preparation of financial statements in accordance with U.S. generally accepted accounting principles 
requires management to make estimates and assumptions that affect the reported amounts of assets and 
liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the 
reported amounts of revenues and expenses during the reporting period.  These estimates and assumptions may 
require significant judgment about matters that are inherently uncertain, and future events are likely to occur 
that may require management to change them.  Accordingly, management regularly reviews these estimates and 
assumptions based on historical experience, changes in the business environment and other factors that 
management believes to be reasonable under the circumstances.  Management discusses the development, 
selection and disclosures concerning critical accounting estimates with the Audit Committee of its Board of 
Directors. 

Pensions and Other Postretirement Benefits 

Accounting for pensions and other postretirement benefit plans requires management to make several estimates 
and assumptions (see Note 10).  These include the expected rate of return from investment of the plans' assets, 
projected increases in medical costs and the expected retirement age of employees as well as their projected 
earnings and mortality.  In addition, the amounts recorded are affected by changes in the interest rate 
environment because the associated liabilities are discounted to their present value.  Management makes these 
estimates based on the company's historical experience and other information that it deems pertinent under the 
circumstances (for example, expectations of future stock market performance).  Management engages an 

K33 

 
 
 
  
 
  
  
 
independent consulting actuarial firm to assist it in selecting appropriate assumptions and valuing its related 
liabilities. 

NS' net pension benefit, which is included in “Compensation and benefits” on its Consolidated Statements of 
Income, was $29 million for the year ended Dec. 31, 2006.  In recording this amount, NS assumed a long-term 
investment rate of return of 9%.  Investment experience of the pension fund over the past 10-, 15- and 20-year 
periods has been a rate of return in excess of 10% and supports the current rate of return assumption.  A one 
percentage point change to this rate of return assumption would result in a $19 million change to the pension credit 
and, as a result, an equal change in “Compensation and benefits” expense.  Changes that are reasonably likely to 
occur in assumptions concerning retirement age, projected earnings and mortality would not be expected to have a 
material effect on NS' net pension benefit or net pension asset in the future.  The net pension asset is recorded at its 
net present value using a discount rate that is based on the current interest rate environment in light of the timing of 
expected benefit payments.  Specifically, NS refers to Moody’s seasoned Aa corporate bond yields and the changes 
in such yields; therefore, management has little discretion in this assumption.   

NS' net cost for other postretirement benefits, which is also included in “Compensation and benefits,” was $70 
million for the year ended Dec. 31, 2006.  In recording this expense and valuing the net liability for other 
postretirement benefits, which is included in “Other postretirement benefits” as disclosed in Note 10, 
management estimated future increases in health-care costs.  These assumptions, along with the effect of a one 
percentage point change in them, are described in Note 10. 

Properties and Depreciation 

Most of NS' total assets are comprised of long-lived railway properties (see Note 5).  As disclosed in Note 1, NS' 
properties are depreciated using group depreciation.  Rail is depreciated primarily on the basis of use measured by 
gross-ton miles.  Other properties are depreciated generally using the straight-line method over the lesser of 
estimated service or lease lives.  NS reviews the carrying amount of properties whenever events or changes in 
circumstances indicate that such carrying amount may not be recoverable based on future undiscounted cash 
flows.  Assets that are deemed impaired as a result of such review are recorded at the lesser of carrying amount or 
fair value. 

NS' depreciation expense is based on management's assumptions concerning service lives of its properties as well 
as the expected net salvage that will be received upon their retirement.  These assumptions are the product of 
periodic depreciation studies that are performed by an outside firm of consulting engineers.  These studies analyze 
NS' historical patterns of asset use and retirement and take into account any expected change in operation or 
maintenance practices.  NS' recent experience with these studies has been that while they do result in changes in 
the rates used to depreciate its properties, these changes have not caused a significant effect to its annual 
depreciation expense.  The studies may also indicate that the recorded amount of accumulated depreciation is 
deficient (or in excess) of the amount indicated by the study.  Any such deficiency (or excess) is amortized as a 
component of depreciation expense over the remaining service lives of the affected class of property.  NS' 
depreciation expense for the year ended Dec. 31, 2006, amounted to $738 million.  NS' weighted-average 
depreciation rates for 2006 are disclosed in Note 5; a one-tenth percentage point increase (or decrease) in these 
rates would have resulted in a $26 million increase (or decrease) to NS' depreciation expense. 

Personal Injury, Environmental and Legal Liabilities 

NS' expense for “Casualties and other claims” amounted to $220 million for the year ended Dec. 31, 2006.  Most 
of this expense was composed of NS' accrual related to personal injury liabilities.  Job-related personal injury and 
occupational claims are subject to FELA, which is applicable only to railroads.  FELA’s fault-based tort system 
produces results that are unpredictable and inconsistent as compared with a no-fault worker’s compensation 
system.  The variability inherent in this system could result in actual costs being very different from the liability 
recorded.  In all cases, NS records a liability when the expected loss for the claim is both probable and estimable. 

K34 

  
 
 
  
 
 
  
NS engages an independent consulting actuarial firm to aid in valuing its personal injury liability and determining 
the amount to accrue during the year.  For employee personal injury cases, the actuarial firm studies NS' historical 
patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences.  An 
estimate of the ultimate amount of the liability, which includes amounts for incurred but unasserted claims, is 
based on the results of this analysis.  For occupational injury claims, the actuarial firm studies NS’ history of 
claim filings, severity, payments and other relevant facts.  Additionally, the estimate of the ultimate loss for 
occupational injuries includes a provision for those claims that have been incurred but not reported by projecting 
NS’ experience into the future as far as can be reasonably determined.  NS has recorded this actuarially 
determined liability.  The liability is dependent upon many individual judgments made as to the specific case 
reserves as well as the judgments of the consulting actuary and management in the periodic studies.  Accordingly, 
there could be significant changes in the liability, which NS would recognize when such a change became known.  
The most recent actuarial study, completed in the fourth quarter of 2006, resulted in a slight increase to NS' 
personal injury liability during the fourth quarter.  While the liability recorded is supported by the most recent 
study, it is reasonably possible that the liability could be higher or lower. 

NS is subject to various jurisdictions' environmental laws and regulations.  It is NS' policy to record a liability 
where such liability or loss is probable and its amount can be estimated reasonably (see Note 17).  Claims, if any, 
against third parties for recovery of cleanup costs incurred by NS, are reflected as receivables (when collection is 
probable) in the Consolidated Balance Sheets and are not netted against the associated NS liability.  
Environmental engineers regularly participate in ongoing evaluations of all known sites and in determining any 
necessary adjustments to liability estimates.  NS also has established an Environmental Policy Council, composed 
of senior managers, to oversee and interpret its environmental policy. 

Operating expenses for environmental matters totaled approximately $19 million in 2006, $16 million in 2005 and 
$11 million in 2004, and capital expenditures totaled approximately $6 million in 2006, and $9 million in each of 
2005 and 2004.  Capital expenditures in 2007 are expected to be comparable to those in 2006. 

NS' Consolidated Balance Sheets included liabilities for environmental exposures in the amount of $54 million at 
Dec. 31, 2006, and $58 million at Dec. 31, 2005 (of which $12 million was accounted for as a current liability at 
Dec. 31, 2006, and 2005).  At Dec. 31, 2006, the liability represented NS' estimate of the probable cleanup and 
remediation costs based on available information at 172 identified locations.  On that date, 15 sites accounted for 
$29 million of the liability, and no individual site was considered to be material.  NS anticipates that much of this 
liability will be paid out over five years; however, some costs will be paid out over a longer period. 

At some of the 172 locations, certain NS subsidiaries, usually in conjunction with a number of other parties, have 
been identified as potentially responsible parties by the Environmental Protection Agency (EPA) or similar state 
authorities under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or 
comparable state statutes, which often impose joint and several liability for cleanup costs. 

With respect to known environmental sites (whether identified by NS or by the EPA or comparable state 
authorities), estimates of NS' ultimate potential financial exposure for a given site or in the aggregate for all 
such sites are necessarily imprecise because of the widely varying costs of currently available cleanup 
techniques, the likely development of new cleanup technologies, the difficulty of determining in advance the 
nature and full extent of contamination and each potential participant's share of any estimated loss (and that 
participant's ability to bear it), and evolving statutory and regulatory standards governing liability.  NS 
estimates its environmental remediation liability on a site-by-site basis, using assumptions and judgments that 
management deems appropriate for each site.  As a result, it is not practical to quantitatively describe the effects 
of changes in these many assumptions and judgments.  NS has consistently applied its methodology of 
estimating its environmental liabilities. 

Based on its assessment of the facts and circumstances now known, management believes that it has recorded the 
probable costs for dealing with those environmental matters of which NS is aware.  Further, management believes 

K35 

 
  
 
 
 
  
that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect 
on NS' financial position, results of operations or liquidity. 

Norfolk Southern and certain subsidiaries are defendants in numerous lawsuits and other claims relating 
principally to railroad operations.  When management concludes that it is probable that a liability has been 
incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to expenses.  
While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future 
developments, in management's opinion the recorded liability, if any, is adequate to cover the future payment of 
such liability and claims.  However, the final outcome of any of these lawsuits and claims cannot be predicted 
with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be 
significant to results of operations in a particular year or quarter.  Any adjustments to recorded liabilities will be 
reflected in expenses in the periods in which such adjustments are known. 

On Oct. 19, 2006, the Pennsylvania Department of Environmental Protection (PDEP) issued an assessment of 
civil penalties against NS and filed a complaint for civil penalties with the Pennsylvania Environmental Hearing 
Board (EHB) requesting that the EHB impose civil penalties upon NS for alleged violations of state 
environmental laws and regulations resulting from a discharge of sodium hydroxide which occurred as a result of 
the derailment of a NS train in Norwich Township, Pennsylvania, on June 30, 2006.  The PDEP’s actions seek to 
impose combined penalties of $8,890,000 for alleged past violations and $46,420 per day for alleged ongoing 
violations of state environmental laws and regulations.  NS believes that the monetary penalties sought by the 
PDEP are excessive.  Accordingly, NS intends to vigorously defend the action and has appealed the fines to the 
EHB.  In addition, NS expects the Pennsylvania Fish and Boat Commission to impose a monetary penalty on NS 
for damages alleged to have been caused by this accident.  NS does not believe that the outcome of these 
proceedings will have a material effect on its financial position, results of operations, or liquidity.  

Income Taxes 

NS' net long-term deferred tax liability totaled $6.4 billion at Dec. 31, 2006 (see Note 3).  This liability is 
estimated based on the expected future tax consequences of items recognized in the financial statements.  After 
application of the federal statutory tax rate to book income, judgment is required with respect to the timing and 
deductibility of expenses in the corporate income tax returns.  For state income and other taxes, judgment is also 
required with respect to the apportionment among the various jurisdictions.  A valuation allowance is recorded if 
management expects that it is more likely than not that its deferred tax assets will not be realized.  NS had a 
$9 million valuation allowance on $637 million of deferred tax assets as of Dec. 31, 2006, reflecting the 
expectation that most of these assets will be realized.  In addition, NS has a recorded liability for its estimate of 
potential income tax exposures.  Management believes this liability for potential exposure to be adequate.  Income 
tax expense is adjusted to the extent the final outcome of these matters differs from the amounts recorded.  For 
every one half percent change in the 2006 effective rate net income would have changed by $11 million. 

OTHER MATTERS 

Labor Agreements 

Approximately 26,000, or about 85%, of NS' railroad employees are covered by collective bargaining agreements 
with various labor unions.  These agreements remain in effect until changed pursuant to the Railway Labor Act 
(RLA).  NS largely bargains in concert with other major railroads.  Moratorium provisions in the labor 
agreements govern when the railroads and the unions may propose labor agreement changes.  The current 
bargaining round began in late 2004.  Industry issues include contracting out of certain work and employee 
contributions for medical and other benefits.   

K36 

  
 
 
  
 
 
 
  
After a period of direct negotiations, either party may file for mediation if it believes insufficient progress is being 
made.  The status quo is preserved during mediation while a federal mediator assists the parties in their efforts to 
reach agreement.  The railroads are currently in mediation with all of the involved labor unions.  If the National 
Mediation Board, a federal agency, were to terminate mediation, it would, at that time, propose that the parties 
arbitrate their differences.  A strike could occur 30 days thereafter if the parties did not accept arbitration. However, 
if arbitration is rejected by either party the President of the United States of America could then appoint an 
Emergency Board which would delay any strike for a further 60 days while the Board made recommendations and 
the parties engaged in further negotiations.  The outcome of the negotiations cannot be determined at this point.  

Market Risks and Hedging Activities 

NS has used derivative financial instruments to reduce the risk of volatility in its diesel fuel costs and to manage 
its overall exposure to fluctuations in interest rates. 

In 2001, NS began a program to hedge a portion of its diesel fuel consumption.  The intent of the program was to 
assist in the management of NS' aggregate risk exposure to fuel price fluctuations, which can significantly affect 
NS' operating margins and profitability, through the use of one or more types of derivative instruments.  No new 
hedges have been entered into since May of 2004, and the last remaining contracts were settled in the second 
quarter of 2006, bringing an end to the benefits from the program.  Diesel fuel costs represented 14% of NS' 
operating expenses for 2006, 11% for 2005 and 8% for 2004.   

NS manages its overall exposure to fluctuations in interest rates by issuing both fixed- and floating-rate debt 
instruments and by entering into interest-rate hedging transactions to achieve an appropriate mix within its debt 
portfolio. 

At Dec. 31, 2006, NS' debt subject to interest rate fluctuations totaled $237 million.  A 1% point increase in 
interest rates would increase NS' total annual interest expense related to all its variable debt by approximately 
$2 million.  Management considers it unlikely that interest rate fluctuations applicable to these instruments will 
result in a material adverse effect on NS' financial position, results of operations or liquidity. 

Some of NS' capital leases, which carry an average fixed rate of 7%, were effectively converted to variable rate 
obligations using interest rate swap agreements.  On Dec. 31, 2006, the average pay rate under these agreements 
was 6%, and the average receive rate was 7%.  During 2006 and 2005, the effect of the swaps was to reduce interest 
expense by $1 million and $2 million, respectively.  A portion of the lease obligations is payable in Japanese yen.  
NS eliminated the associated exchange rate risk at the inception of each lease with a yen deposit sufficient to fund 
the yen-denominated obligation.  Most of these deposits are held by foreign banks, primarily Japanese.  As a result, 
NS is exposed to financial market risk relative to Japan.  Counterparties to the interest rate swaps and Japanese 
banks holding yen deposits are major financial institutions believed by management to be creditworthy. 

New Accounting Pronouncements 

In June 2006, the FASB issued Interpretation No. (FIN) 48, “Accounting for Uncertainty in Income Taxes.”  This 
Interpretation clarifies accounting for uncertainty in income taxes recognized in an enterprise’s financial 
statements in accordance with SFAS No. 109, “Accounting for Income Taxes.”  FIN 48 prescribes a recognition 
threshold and measurement attribute for a tax position taken or expected to be taken in a tax return.  Under the 
guidelines of FIN 48, an entity should recognize the financial statement benefit of a tax position if it determines 
that it is more likely than not that the position will be sustained on examination.  NS will adopt this Interpretation 
in the first quarter of 2007 and expects it will not have a material effect on NS’ consolidated financial statements. 

In September 2006, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting 
Standards (SFAS) No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement 
Plans.”  This statement requires an employer to recognize in its statement of financial position the overfunded or 

K37 

 
  
  
 
 
 
 
 
 
underfunded status of defined benefit pension and postretirement plans measured as the difference between the 
fair value of plan assets and the benefit obligation.  Employers must also recognize as a component of other 
comprehensive income, net of tax, the actuarial gains and losses and the prior service costs, credits and transition 
costs that arise during the period.  NS adopted this statement in the fourth quarter of 2006 (see Note 10). 

In December 2004, the FASB issued SFAS No. 123(R), “Share-Based Payment.”  This statement establishes 
standards for accounting for transactions in which an entity exchanges its equity instruments for goods or services, 
such as stock-based compensation plans.  NS adopted this standard in the first quarter of 2006 (see Note 1).   

Inflation 

In preparing financial statements, U.S. generally accepted accounting principles require the use of historical cost 
that disregards the effects of inflation on the replacement cost of property.  NS, a capital-intensive company, has 
most of its capital invested in such assets.  The replacement cost of these assets, as well as the related depreciation 
expense, would be substantially greater than the amounts reported on the basis of historical cost. 

Proposed Legislation and Regulations on Safety and Transportation of Hazardous Materials 

Regulations proposed by the Department of Homeland Security in late 2006 would mandate that railroads adopt 
chain of custody and security measures.  If enacted, such regulations could cause service degradation and higher 
costs for the transportation of toxic inhalation hazard materials.  In addition, certain local governments have 
sought to enact ordinances banning hazardous materials moving by rail within their borders.  Some legislators 
have contemplated pre-notification requirements for hazardous material shipments.  If promulgated, such 
ordinances could require the re-routing of hazardous materials shipments, with the potential for significant 
additional costs and network inefficiencies.  Accordingly, NS will oppose efforts to impose unwarranted 
regulation in this area. 

FORWARD-LOOKING STATEMENTS 

This Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-
looking statements that may be identified by the use of words like “believe,” “expect,” “anticipate” and “project.” 
Forward-looking statements reflect management's good-faith evaluation of information currently available.  
However, such statements are dependent on and, therefore, can be influenced by, a number of external variables 
over which management has little or no control, including:  domestic and international economic conditions; 
interest rates; the business environment in industries that produce and consume rail freight; competition and 
consolidation within the transportation industry; the operations of carriers with which NS interchanges; acts of 
terrorism or war; fluctuation in prices of key materials, in particular diesel fuel; labor difficulties, including strikes 
and work stoppages; legislative and regulatory developments; changes in securities and capital markets; 
disruptions to NS’ technology infrastructure including computer systems; and natural events such as severe 
weather, hurricanes and floods.  For more discussion about each risk factor, see Part I, Item 1A “Risk Factors.”  
Forward-looking statements are not, and should not be relied upon as a guarantee of future performance or results, 
nor will they necessarily prove to be accurate indications of the times at or by which any such performance or 
results will be achieved.  As a result, actual outcomes and results may differ materially from those expressed in 
forward-looking statements.  NS undertakes no obligation to update or revise forward-looking statements.

Report of Management 

February 20, 2007 

To the Stockholders 
Norfolk Southern Corporation 

Management is responsible for establishing and maintaining adequate internal control over financial reporting.  In 
order to ensure that the Corporation's internal control over financial reporting is effective, management regularly 
assesses such controls and did so most recently for its financial reporting as of December 31, 2006.  This 
assessment was based on criteria for effective internal control over financial reporting described in Internal 
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission.  Based on this assessment, management has concluded that the Corporation maintained effective 
internal control over financial reporting as of December 31, 2006. 

KPMG LLP, independent registered public accounting firm, has audited the Corporation's financial statements 
and has reported on management's assessment of the effectiveness of the Corporation's internal control over 
financial reporting as of December 31, 2006.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders 
Norfolk Southern Corporation: 

We have audited management’s assessment, included in the accompanying Report of Management, that Norfolk 
Southern Corporation maintained effective internal control over financial reporting as of December 31, 2006, 
based on criteria established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). Norfolk Southern Corporation’s management is responsible 
for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of 
internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment 
and an opinion on the effectiveness of Norfolk Southern Corporation’s internal control over financial reporting 
based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects. Our audit 
included obtaining an understanding of internal control over financial reporting, evaluating management’s 
assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such 
other procedures as we considered necessary in the circumstances. We believe that our audit provides a 
reasonable basis for our opinion. 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with U.S. generally accepted accounting principles. A company’s internal control over financial 
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable 
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide 
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the company 
are being made only in accordance with authorizations of management and directors of the company; and (3) 
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that 
controls may become inadequate because of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate. 

In our opinion, management’s assessment that Norfolk Southern Corporation maintained effective internal control 
over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria 
established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (COSO). Also in our opinion, Norfolk Southern Corporation maintained, in all 
material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria 
established in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (COSO).

Report of Independent Registered Public Accounting Firm  

The Board of Directors and Stockholders 
Norfolk Southern Corporation: 

We have audited the accompanying consolidated balance sheets of Norfolk Southern Corporation and subsidiaries 
as of December 31, 2006 and 2005, and the related consolidated statements of income, changes in stockholders’ 
equity and cash flows for each of the years in the three-year period ended December 31, 2006. In connection with 
our audits of the consolidated financial statements, we have also audited the financial statement schedule as listed 
in Item 15(A)2. These consolidated financial statements and financial statement schedule are the responsibility of 
Norfolk Southern Corporation’s management. Our responsibility is to express an opinion on these consolidated 
financial statements and financial statement schedule based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the 
accounting principles used and significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the 
financial position of Norfolk Southern Corporation and subsidiaries as of December 31, 2006 and 2005, and the 
results of their operations and their cash flows for each of the years in the three-year period ended December 31, 
2006, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial 
statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, 
presents fairly, in all material respects, the information set forth therein. 

As discussed in note 1 to the consolidated financial statements, Norfolk Southern Corporation adopted Statement 
of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment, effective January 1, 2006, and 
Statement of Financial Accounting Standards No. 158, Employers’ Accounting for Defined Benefit Pension and 
Other Postretirement Plans, effective December 31, 2006. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the effectiveness of Norfolk Southern Corporation’s internal control over financial reporting as of 
December 31, 2006, based on criteria established in Internal Control – Integrated Framework, issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated 
February 20, 2007, expressed an unqualified opinion on management’s assessment of, and the effective operation 
of, internal control over financial reporting.

Norfolk Southern Corporation and Subsidiaries 
Notes to Consolidated Financial Statements 

The following Notes are an integral part of the Consolidated Financial Statements. 

1.  Summary of Significant Accounting Policies 

Description of Business 

Norfolk Southern Corporation is a Virginia-based holding company engaged principally in the rail transportation 
business, operating approximately 21,000 route miles primarily in the East and Midwest.  These consolidated 
financial statements include Norfolk Southern Corporation (Norfolk Southern) and its majority-owned and 
controlled subsidiaries (collectively, NS).  Norfolk Southern's major subsidiary is Norfolk Southern Railway 
Company (NSR).  All significant intercompany balances and transactions have been eliminated in consolidation. 

The railroad transports raw materials, intermediate products and finished goods classified in the following market 
groups (percent of total railway operating revenues in 2006): coal (25%); intermodal (21%); metals/construction 
(12%); chemicals (12%); agriculture/consumer products/government (11%); automotive (10%); and 
paper/clay/forest products (9%).  Although most of NS’ customers are domestic, ultimate points of origination or 
destination for some of the products transported (particularly coal bound for export and some intermodal 
containers) may be outside the United States.  Approximately 85% of NS' railroad employees are covered by 
collective bargaining agreements with various labor unions. 

Use of Estimates 

The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires 
management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 
disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of 
revenues and expenses during the reporting period.  Management reviews its estimates, including those related to 
the recoverability and useful lives of assets, as well as liabilities for litigation, environmental remediation, 
casualty claims, income taxes, and pension and other postretirement benefits.  Changes in facts and circumstances 
may result in revised estimates. 

Revenue Recognition 

Transportation revenue is recognized proportionally as a shipment moves from origin to destination and related 
expenses are recognized as incurred.  Refunds (which are primarily volume-based incentives) are recorded as a 
reduction to revenues on the basis of management's best estimate of projected liability, which is based on historical 
activity, current traffic counts and the expectation of future activity.  NS regularly monitors its contract refund 
liability, and historically, the estimates have not differed significantly from the amounts ultimately refunded.  
Switching, demurrage and other incidental service revenues are recognized when the services are performed. 

Derivatives 

NS does not engage in the trading of derivatives.  NS uses derivative financial instruments to reduce the risk of 
volatility in its diesel fuel costs and in the management of its mix of fixed and floating-rate debt.  Management 
has determined that these derivative instruments qualify as either fair-value or cash-flow hedges, having values 
that highly correlate with the underlying hedged exposures, and has designated such instruments as hedging 
transactions.  Income and expense related to the derivative financial instruments are recorded in the same category 
as generated by the underlying asset or liability.  Credit risk related to the derivative financial instruments is 

K48 

  
  
  
  
  
  
 
 
  
 
  
 
  
considered to be minimal and is managed by requiring high credit standards for counterparties and periodic 
settlements (see Note 16). 

Stock-Based Compensation 

NS has stock-based employee compensation plans, which are more fully described in Note 11.  Through Dec. 31, 
2005, NS applied the intrinsic value recognition and measurement principles of APB Opinion No. 25, 
“Accounting for Stock Issued to Employees” (APB Opinion 25), and related interpretations in accounting for 
these plans (See “Required Accounting Changes in 2006,” below). 

The following table illustrates the effect on net income and earnings per share if NS had applied the fair value 
recognition provisions of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based 
Compensation” (SFAS 123), to stock-based employee compensation:

Required Accounting Changes in 2006 

Effective January 1, 2006, NS adopted Statement of Financial Accounting Standards, No. 123(R), “Share-Based 
Payment,” [SFAS 123(R)].  This statement applies to awards granted, modified, repurchased or cancelled after the 
effective date as well as awards that are unvested at the effective date and includes, among other things, the 
requirement to expense the fair value of stock options.  The standard also requires that awards to be settled in cash 
be measured at fair value at each reporting date until ultimate settlement.  NS adopted SFAS 123(R) using the 
modified prospective method, which requires application of the standard to all awards granted, modified, 
repurchased or cancelled on or after January 1, 2006, and to all awards for which the requisite service has not 
been rendered as of such date.  In accordance with the modified prospective approach, prior period financial 
statements have not been restated to reflect the impact of SFAS 123(R).  As compared to amounts that would 
have been recognized under APB Opinion 25, the adoption of SFAS 123(R) resulted in $27 million of additional 
compensation expense for 2006, including the immediate expensing of 2006 grants made to retirement-eligible 
employees, which reduced net income by $20 million, or 5 cents per basic and diluted share.  Under SFAS 
123(R), all new awards granted to retirement eligible employees must be expensed immediately.  Under APB 
Opinion No. 25 and related interpretations, such awards were amortized over the stated service period.  Such 
awards were treated similarly under SFAS 123 in the pro forma amounts disclosed in the preceding table.

Effective Dec. 31, 2006, NS adopted Statement of Financial Accounting Standards (SFAS) No. 158, “Employers’ 
Accounting for Defined Benefit Pension and Other Postretirement Plans” (see Note 10). 

Cash Equivalents 

“Cash equivalents” are highly liquid investments purchased three months or less from maturity. 

Allowance for Doubtful Accounts 

NS' allowance for doubtful accounts was $5 million at Dec. 31, 2006, and $6 million at Dec. 31, 2005.  To 
determine its allowance for doubtful accounts, NS evaluates historical loss experience (which has not been 
significant), the characteristics of current accounts, as well as general economic conditions and trends. 

Materials and Supplies 

“Materials and supplies,” consisting mainly of fuel oil and items for maintenance of property and equipment, are 
stated at the lower of average cost or market.  The cost of materials and supplies expected to be used in capital 
additions or improvements is included in “Properties.” 

Investments 

Debt securities classified as “held-to-maturity” are reported at amortized cost and marketable equity and debt 
securities classified as “trading” or “available-for-sale” are recorded at fair value.  Unrealized after-tax gains 
and losses for investments designated as “available-for-sale,” are recognized in “Accumulated other 
comprehensive loss.” 

Investments where NS has the ability to exercise significant influence over but does not control the entity are 
accounted for using the equity method in accordance with APB Opinion No. 18, “The Equity Method of 
Accounting for Investments in Common Stock.” 

Properties 

“Properties” are stated principally at cost and are depreciated using group depreciation.  Rail is depreciated 
primarily on the basis of use measured by gross ton-miles.  Other properties are depreciated generally using the 
straight-line method over the lesser of estimated service or lease lives.  Depletion of natural resources (see Note 2) 
is based on units of production.  Depreciation in the Consolidated Statements of Cash Flows includes depreciation 
and depletion.  NS capitalizes interest on major capital projects during the period of their construction.  
Expenditures, including those on leased assets that extend an asset's useful life or increase its utility, are 
capitalized.  Costs related to repairs and maintenance activities that do not extend an asset’s useful life or increase 
its utility are expensed when such repairs are performed.  When properties other than land and nonrail assets are 
sold or retired in the ordinary course of business, the cost of the assets, net of sale proceeds or salvage, is charged 
to accumulated depreciation, and no gain or loss is recognized through income.  Gains and losses on disposal of 
land and nonrail assets are included in “Other income - net” (see Note 2) since such income is not a product of 
NS’ railroad operations. 

NS reviews the carrying amount of properties whenever events or changes in circumstances indicate that such 
carrying amount may not be recoverable based on future undiscounted cash flows.  Assets that are deemed 
impaired as a result of such review are recorded at the lower of carrying amount or fair value. 

Reclassifications 

Certain comparative prior year amounts have been reclassified to conform to the current year presentation.

“Other income - net” includes income and costs not part of rail operations and the income generated by the 
activities of NS' noncarrier subsidiaries as well as the costs incurred by those subsidiaries in their operations.  NS 
has a 40.5% interest in a limited liability company that owns and operates facilities that produce synthetic fuel 
from coal.  The production of synthetic fuel results in tax credits as well as expenses related to the investments.  
The expenses are included in “Equity in losses of partnerships” above. 

“Other current assets” in the Consolidated Balance Sheets includes prepaid interest of $50 million at Dec. 31, 
2006, and $47 million at Dec. 31, 2005, arising from corporate-owned life insurance borrowings.

In June 2005, Ohio enacted tax legislation that phases out its Corporate Franchise Tax, which was generally based 
on federal taxable income, and phases in a new gross receipts tax called the Commercial Activity Tax, which is 
based on current year sales and rentals.  The phased elimination of the Corporate Franchise Tax resulted in a 
reduction in NS’ deferred income tax liability, as required by Statement of Financial Accounting Standards 
No. 109, “Accounting for Income Taxes,” which, as noted above, decreased deferred tax expense by $96 million. 

Deferred Tax Assets and Liabilities 

Certain items are reported in different periods for financial reporting and income tax purposes.  Deferred tax 
assets and liabilities are recorded in recognition of these differences.  The tax effects of temporary differences that 
give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows: 

Deferred tax assets: 
   Compensation and benefits, including post-retirement 
   Accruals, including casualty and other claims 
   Other 
      Total gross deferred tax assets 
   Less valuation allowance 
      Net deferred tax asset

Except for amounts for which a valuation allowance has been provided, management believes that it is more 
likely than not that future taxable income will be sufficient to realize the deferred tax assets.  The valuation 
allowance at the end of each year relates to subsidiary state income tax net operating losses that may not be 
utilized prior to their expiration.  The total valuation allowance decreased $1 million in 2006, $3 million in 2005 
and $1 million in 2004. 

Internal Revenue Service (IRS) Reviews 

Consolidated federal income tax returns have been examined and Revenue Agent Reports have been received for 
all years up to and including 2003.  In 2004, the favorable resolution of the IRS audit of a synthetic fuel-related 
investment is reflected in the “Tax credits” line of the reconciliation of statutory rate to the effective rate.  The 
consolidated federal income tax returns for 2004 and 2005 are being audited by the IRS.  Management believes 
that adequate provision has been made for any additional taxes and interest thereon that might arise as a result of 
IRS examinations.

The $391 million in “Short-term investments” is classified as available-for-sale, of which approximately three-
quarters mature within six months.  Unrealized gains from short-term investments were approximately $1 million at 
Dec. 31, 2006, and unrealized losses from short-term investments were approximately $1 million at Dec. 31, 2005. 

Other equity method investments, shown above, includes NS’ $100 million investment in MSLLC, a joint venture 
formed with Kansas City Southern, made in 2006. 

Investment in Conrail and Operations Over Its Lines 

Overview 

Through a limited liability company, Norfolk Southern and CSX Corporation (CSX) jointly own Conrail Inc. 
(Conrail), whose primary subsidiary is Consolidated Rail Corporation (CRC).  NS has a 58% economic and 
50% voting interest in the jointly owned entity, and CSX has the remainder of the economic and voting 
interests.  CRC owns and operates certain properties (the Shared Assets Areas) for the joint and exclusive 

K53 

 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
benefit of NSR and CSX Transportation Inc. (CSXT).  The costs of operating the Shared Assets Areas are 
borne by NSR and CSXT based on usage.  In addition, NSR and CSXT pay CRC a fee for access to the Shared 
Assets Areas. 

Conrail Corporate Reorganization 

On August 27, 2004, NS, CSX and Conrail completed a reorganization of Conrail (Conrail Corporate 
Reorganization), which established direct ownership and control by NSR and CSXT of two former CRC 
subsidiaries, Pennsylvania Lines LLC (PRR) and New York Central Lines LLC (NYC), respectively.  Prior to the 
Conrail Corporate Reorganization, NSR operated the routes and assets of PRR and CSXT operated the routes and 
assets of NYC, each in accordance with operating and lease agreements.  Pursuant to the Conrail Corporate 
Reorganization, the operating and lease agreements were terminated and PRR and NYC were merged into NSR 
and CSXT, respectively.  The reorganization did not involve the Shared Assets Areas and did not affect the 
competitive rail service provided in the Shared Assets Areas.  Conrail continues to own, manage and operate the 
Shared Assets Areas as previously approved by the Surface Transportation Board (STB). 

As a part of the Conrail Corporate Reorganization, Conrail restructured its existing unsecured and secured 
public indebtedness, with the consent of Conrail’s debtholders.  Prior to the restructuring, there were two series 
of unsecured public debentures with an outstanding principal amount of approximately $800 million and 13 
series of secured debt with an outstanding principal amount of approximately $300 million.  Guaranteed debt 
securities were offered in an approximate 58%/42% ratio in exchange for Conrail’s unsecured debentures.  Of 
the $800 million unsecured public debentures, $779 million were tendered and accepted for exchange, and 
NSR issued unsecured public debentures with a total principal of $452 million and an issue-date fair value of 
$595 million.  Conrail’s secured debt and lease obligations remain obligations of Conrail and are supported by 
leases and subleases which are the direct lease and sublease obligations of NSR or CSXT.  Substantially all of 
these NSR obligations are capital leases and, accordingly, are a component of NS’ capital lease obligations (see 
Note 7). 

NS accounted for the transaction at fair value, which resulted in the recognition of a $40 million net gain 
(reported in “Other income – net”) in 2004 from the tax-free distribution to NS of a portion of its investment in 
Conrail.  Originally in 2004, the gain was calculated and reported as $53 million.  However, in December 
2006, CSX determined that the value for a portion of a rail yard transferred from Conrail to CSX had been 
omitted.  Accordingly, the gain was adjusted in the accompanying Consolidated Statement of Income for 2004 
to reflect an immaterial correction of $13 million.  In addition, the Consolidated Balance Sheet as of December 
31, 2005 reflects corresponding adjustments to the amounts previously reported for Investments (reduction of 
$32 million), Properties (increase of $30 million), Deferred income tax liabilities (increase of $11 million) and 
Retained income (decrease of $13 million). 

NS concluded that fair value was the appropriate measurement for 42% of PRR because the transaction 
resulted in the complete ownership and control of PRR.  The remaining 58% of PRR was recorded at NS’ 
carryover basis.  As a result of the transaction, NS’ investment in Conrail does not include amounts related to 
PRR and NYC beginning in 2005.  Instead the assets and liabilities of PRR are reflected in their respective line 
items in NS’ Consolidated Balance Sheet and amounts due to PRR were extinguished.

described above ($ in millions):

The amounts shown above for the net assets received reflect the fair value of such assets.  Properties were 
valued based on information received from an independent valuation consultant.  The assets of PRR included 
the note due from NSR discussed below under the heading “Related Party Transactions,” which resulted in its 
effectively being extinguished.  Debt was recorded at fair value based on interest rates at the time of the 
reorganization.  The reduction to NS’ investment in Conrail represented the removal of amounts related to NS’ 
equity interests in PRR and NYC as well as amounts related to the Conrail debt that was exchanged or 
effectively assumed by the leases and subleases entered into to support those obligations. 

On the Consolidated Statements of Income, “Conrail rents and services” was reduced as a result of the 2004 
transaction.  After the Conrail Corporate Reorganization, “Conrail rents and services” reflects only the 
expenses associated with the Shared Assets Areas, and other expenses (primarily the depreciation related to the 
PRR assets) are reflected in their respective line items in the Consolidated Statements of Income.  The 
transaction’s impact on 2004 net income was the $40 million gain discussed above.  Prospectively, the 
transaction will have no effect on revenues and will not have a significant ongoing effect on net income.  Had 
the transaction been consummated before the periods presented, there would have been no change in revenues 
and no significant change to net income. 

NS is continuing to apply the equity method of accounting to its remaining investment in Conrail in accordance 
with APB Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock."  NS is 
amortizing the excess of the purchase price over Conrail's net equity using the principles of purchase 
accounting, based primarily on the estimated remaining useful lives of Conrail's depreciable property and 
equipment, including the related deferred tax effect of the differences in tax and accounting bases for certain 
assets, as all of the purchase price at acquisition was allocable to Conrail’s tangible assets and liabilities.  At 
Dec. 31, 2006, the difference between NS' investment in Conrail and its share of Conrail's underlying net 
equity was $556 million. 

Related-Party Transactions 

CRC owns and operates the Shared Assets Areas for the joint and exclusive benefit of NSR and CSXT.  NSR and 
CSXT pay CRC a fee for joint and exclusive access to the Shared Assets Areas.  In addition, NSR and CSXT pay, 
based on usage, the costs incurred by CRC to operate the Shared Assets Areas.  Future minimum lease payments 
due to CRC under the Shared Assets Areas agreements are as follows: $26 million in each of 2007 through 2011 
and $318 million thereafter.

*After the reorganization, NS’ equity in the earnings of Conrail, net of amortization, is included in “Other 
income – net,” (see Note 2). 

Prior to the Conrail Corporate Reorganization, a significant portion of the payments made to PRR was 
borrowed back from a subsidiary of PRR under a note due in 2032.  Amounts outstanding under this note 
comprised the long-term balance of “Due to Conrail,” and this note was effectively extinguished by the 
reorganization.  "Due to Conrail" included in “Accounts payable” (see Note 6) is composed principally of 
amounts related to expenses included in "Conrail rents and services," as discussed above.  “Long-term 
advances from Conrail,” included in “Other liabilities” (see Note 9), bear interest at an average rate of 4.4% 
and are due in 2035. 

NS provides certain general and administrative support functions to Conrail, the fees for which are billed in 
accordance with several service-provider arrangements and amount to approximately $7 million annually. 

Summary Financial Information – Conrail 

As a result of the Conrail Corporate Reorganization discussed above, two CRC subsidiaries, PRR and NYC, were 
distributed to NS and CSX, respectively, and CRC’s public indebtedness was restructured.  The results of the 
operations of these subsidiaries are presented in the following 2004 financial information as “Discontinued 
Operations.”  The 2006, 2005 and 2004 summarized information was derived from unaudited financial statements.

2021).  The $218 million cash premium payment is reflected as a reduction of debt in the Consolidated Balance 
Sheet and Statement of Cash Flows and is included in “Discounts and premiums, net.”  The premium is being 
amortized as additional interest expense over the terms of the new debt, resulting in effective interest rates of 
8.7% for the 2029 notes and 9.0% for the 2025 notes. 

In August 2004, pursuant to the Conrail Corporate Reorganization (see Note 4), NSR issued unsecured public 
debentures with a total principal of $452 million ($314 million at 9.75% due 2020 and $138 million at 7.875% 
due 2043) and fair value of $595 million.  This difference is included in “Discounts and premiums, net” and is 
being amortized as a reduction of interest expense over the terms of the notes, resulting in effective interest rates 
of 6.0% for the 2020 notes and 6.2% for the 2043 notes. 

The railroad equipment obligations and the capitalized leases are secured by liens on the underlying equipment.  
Certain lease obligations require the maintenance of yen-denominated deposits, which are pledged to the lessor to 
satisfy yen-denominated lease payments.  These deposits are included in “Other assets” on the balance sheet and 
totaled $85 million at Dec. 31, 2006, and $87 million at Dec. 31, 2005. 

Shelf Registration  

NS has on file with the Securities and Exchange Commission a Form S-3 shelf registration statement, covering 
the issuance of registered debt or equity securities, with $700 million of available capacity.  In 2005, NS issued 
$300 million of 6% senior notes due March 2105 under this shelf registration statement. 

Credit Agreement, Debt Covenants and Commercial Paper 

NS has in place a five-year $1 billion credit facility expiring in 2009.  Any borrowings under the credit agreement 
are contingent on the continuing effectiveness of the representations and warranties made at the inception of the 
agreement.  NS is subject to various financial covenants with respect to its debt and under its credit agreement, 
including a minimum net worth requirement, a maximum leverage ratio restriction, certain restrictions on the 
issuance of further debt by NS or its subsidiaries and the consolidation, merger or sale of substantially all of NS’ 
assets.  At Dec. 31, 2006, NS was in compliance with all financial covenants. 

NS has the ability to issue commercial paper supported by its $1 billion credit agreement.  At Dec. 31, 2006, and 
Dec. 31, 2005, NS had no outstanding commercial paper or borrowings under the credit agreement. 

8.  Lease Commitments 

NS is committed under long-term lease agreements, which expire on various dates through 2067, for equipment, 
lines of road and other property.  The following amounts do not include payments to CRC under the Shared Assets 
Areas agreements (see Note 4).  Future minimum lease payments and operating lease expense are as follows:

Norfolk Southern and certain subsidiaries have both funded and unfunded defined benefit pension plans 
covering principally salaried employees.  Norfolk Southern and certain subsidiaries also provide specified 
health care and death benefits to eligible retired employees and their dependents.  Under the present plans, 
which may be amended or terminated at NS' option, a defined percentage of health care expenses is covered, 
reduced by any deductibles, copayments, Medicare payments and, in some cases, coverage provided under other 
group insurance policies. 

Required Accounting Change 

As of Dec. 31, 2006, NS adopted SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and 
Other Postretirement Plans” (SFAS 158).  This statement requires an employer to recognize in its statement of 
financial position the overfunded or underfunded status of defined benefit pension and postretirement plans 
measured as the difference between the fair value of plan assets and the benefit obligation.  Employers must 
also recognize as a component of other comprehensive income, net of tax, the actuarial gains and losses and the 
prior service costs, credits and transition costs that arise during the period.  As a result of adopting this standard, 
NS reduced its pension asset by $217 million and increased its pension and postretirement liabilities by $258 
million in its Consolidated Balance Sheet, with a corresponding reduction to stockholders’ equity of $292 
million (net of tax) reflected as an increase to accumulated other comprehensive loss.  The adoption of SFAS 
158 has no impact on years prior to 2006 and has no effect on the calculation of expenses for pensions and post-
retirement benefits.

During 2005, NS distributed split dollar life insurance policies to eligible retired employees, which resulted in a 
$12 million reduction of the postretirement benefit obligation. 

NS’ unfunded pension plans, included above, which in all cases have no assets and therefore have an accumulated 
benefit obligation in excess of plan assets, had projected benefit obligations of $152 million at Dec. 31, 2006, and 
$134 million at Dec. 31, 2005, and had accumulated benefit obligations of $125 million at Dec. 31, 2006, and 
$106 million at Dec. 31, 2005.

The estimated net loss and prior service cost for the defined benefit pension plans that will be amortized from 
accumulated other comprehensive loss into net periodic benefit cost over the next year are $9 million and 
$2 million, respectively.  The estimated net loss and prior service benefit for the other defined benefit 
postretirement plans that will be amortized from accumulated other comprehensive loss into net periodic benefit 
cost over the next year are $23 million and $8 million, respectively. 

Pension Assumptions 

Pension and other postretirement benefit costs are determined based on actuarial valuations that reflect appropriate 
assumptions as of the measurement date, ordinarily the beginning of each year.  The funded status of the plans is 
determined using appropriate assumptions as of each year end.  A summary of the major assumptions follows: 

Funded status: 
   Discount rate 
   Future salary increases 
Pension cost: 
   Discount rate 
   Return on assets in plans 
   Future salary increases

For measurement purposes at Dec. 31, 2006 increases in the per capita cost of covered health care benefits were 
assumed to be 10% for 2006 and 9% for 2007.  It is assumed the rate will decrease gradually to an ultimate rate of 
5% for 2011 and remain at that level thereafter.

Eleven investment firms manage NS’ defined benefit pension plan’s assets under investment guidelines approved 
by the Board of Directors.  Investments are restricted to domestic fixed income securities, international fixed 
income securities, domestic and international equity investments and unleveraged exchange-traded options and 
financial futures.  Limitations restrict investment concentration and use of certain derivative instruments.  The 
target asset allocation for equity is 75% of the pension plan’s assets.  Fixed income investments must have an 
average rating of “AA” or better and all fixed income securities must be rated “A” or better except bond index 
funds.  Equity investments must be in liquid securities listed on national exchanges.  No investment is permitted 
in the securities of Norfolk Southern Corporation or its subsidiaries (except through commingled pension trust 
funds).  Investment managers’ returns are expected to meet or exceed selected market indices by prescribed 
margins. 

NS’ pension plan weighted-average asset allocations at Dec. 31, 2006 and 2005, by asset category, were 
as follows:

The postretirement benefit plan assets consist primarily of trust-owned variable life insurance policies with an 
asset allocation at Dec. 31, 2006, of 67% in equity securities and 33% in debt securities compared with 66% in 
equity securities and 34% in debt securities at Dec. 31, 2005.  The target asset allocation for equity is between 
50% and 75% of the plan’s assets. 

The plans’ assumed future returns are based principally on the asset allocation and on the historic returns for the 
plans’ asset classes determined from both actual plan returns and, over longer time periods, market returns for 
those asset classes. 

Contributions and Estimated Future Benefit Payments 

In 2007, NS expects to contribute approximately $8 million to its unfunded pension plans for payments to 
pensioners and $45 million to its other postretirement benefit plans for retiree health benefits.

The other benefit payments include an estimated annual reduction due to the Medicare Part D Subsidy of about $5 
million. 

Other Postretirement Coverage 

Under collective bargaining agreements, NS and certain subsidiaries participate in a multi-employer benefit plan, 
which provides certain postretirement health care and life insurance benefits to eligible union employees.  
Premiums under this plan are expensed as incurred and amounted to $26 million in 2006 and 2005, and 
$20 million in 2004. 

Section 401(k) Plans 

Norfolk Southern and certain subsidiaries provide Section 401(k) savings plans for employees.  Under the plans, 
NS matches a portion of employee contributions, subject to applicable limitations.  NS' expenses under these 
plans were $14 million in 2006, $13 million in 2005 and $12 million in 2004. 

11.  Stock-Based Compensation 

Under the stockholder-approved Long-Term Incentive Plan (LTIP), a committee of nonemployee directors of the 
Board or the chief executive officer (if delegated such authority by the committee) may grant stock options, stock 
appreciation rights (SARs), restricted shares, restricted stock units, performance shares and performance share 
units (PSUs), up to a maximum of 88,025,000 shares of Norfolk Southern Common Stock (Common Stock).  Of 
these shares, 5,000,000 were approved by the Board for issuance to non-officer participants; as a broad-based 
issuance, stockholder approval was not required.  In May 2005, the stockholders approved an amended LTIP 
which provided that 8,500,000 shares of stock previously approved for issuance under LTIP could be granted as 
restricted shares, restricted stock unit shares or performance shares.  Under the Board-approved Thoroughbred 
Stock Option Plan (TSOP), the committee may grant stock options up to a maximum of 6,000,000 shares of 
Common Stock.  Options may be granted for a term not to exceed 10 years and are subject to a vesting period of 
at least one year.  Option exercise prices are at not less than the fair market value of Common Stock on the 
effective date of the grant. 

The LTIP also permits the payment – on a current or a deferred basis and in cash or in stock – of dividend 
equivalents on shares of Common Stock covered by options, PSUs or restricted stock units in an amount 
commensurate with dividends paid on Common Stock.  Tax absorption payments also are authorized for any 
awards under LTIP in amounts estimated to equal the federal and state income taxes applicable to shares of 
Common Stock issued subject to a share retention agreement.

During the first quarter of 2006, a committee of nonemployee directors of NS’ Board granted stock options, 
restricted shares, restricted stock units and PSUs pursuant to the LTIP and granted stock options pursuant to 
the TSOP. 

Accounting Method 

As disclosed in Note 1, prior to the adoption of SFAS 123(R), NS applied APB Opinion 25 and related 
interpretations in accounting for awards made under the plans.  Accordingly, grants of PSUs, restricted shares, 
restricted share units, dividend equivalents, tax absorption payments and SARs resulted in charges to net 
income, while grants of stock options had no effect on net income.  Under SFAS 123(R), all awards will result 
in charges to net income while dividend equivalents are charged to retained earnings.  Related compensation 
costs were $129 million in 2006, $75 million in 2005 and $53 million in 2004.  The total tax effect recognized 
in income in relation to stock-based compensation was a benefit of $44 million in 2006, $27 million in 2005 and 
$19 million in 2004. 

Stock Options 

In the first quarter of 2006, 1,188,700 options were granted under the LTIP and 238,000 options were granted 
under the TSOP.  In each case, the grant price was $49.425, which was the fair market value of Common Stock on 
the date of grant, and the options have a term of ten years but may not be exercised prior to the first anniversary of 
the date of grant.  Holders of the options granted under LTIP receive cash dividend equivalent payments for five 
years commensurate with dividends paid on Common Stock. 

The fair value of each option award in 2006 was measured on the date of grant using a lattice-based option 
valuation model.  Expected volatilities are based on implied volatilities from traded options on Common 
Stock and historical volatility of Common Stock.  NS uses historical data to estimate option exercises and 
employee terminations within the valuation model.  The average expected option life is derived from the 
output of the valuation model and represents the period of time that options granted are expected to be 
outstanding.  The average risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time 
of grant.  For options granted that include dividend equivalent payments, a dividend yield of zero was used.  
For purposes of pro forma information required under SFAS 123, the fair value of the option awards in 2005 
and 2004 was determined using the Black-Scholes option-pricing model.  The assumptions for 2006, 2005 
and 2004 are shown in the following table:

Prior to the adoption of SFAS 123(R), NS presented tax benefits generated from tax deductions in excess of 
compensation costs recognized for share-based awards (excess tax benefits) as operating cash flows in the 
Consolidated Statement of Cash Flows.  Beginning in 2006, SFAS 123(R) requires excess tax benefits to be 
classified as financing cash flows.  Accordingly, “Common stock issued – net” in the Consolidated Statement of 
Cash Flows for the year ended Dec. 31, 2006, included $85 million of such tax benefits. 

In November of 2005, the Board of Directors of NS changed the vesting periods on options granted in January 
2005 from three years to one year in order to reduce future compensation expense.  At the time, each of these 
options had an intrinsic value of approximately $9 and the modification resulted in less than $1 million of 
compensation expense. 

Restricted Shares and Restricted Stock Units 

Restricted share and restricted stock unit grants were 332,150 and 332,150, respectively, in 2006, with a grant-
date fair value of $49.60 and a three-year restriction period, and were 576,240 and 384,160, respectively, in 2005, 
with a grant-date fair value of $34.10 and a five-year restriction period (that may, for restricted shares, be 
accelerated to a three-year restriction period upon achievement of specified performance measures), and were 
359,040 and 239,360, respectively, in 2004 with a grant-date fair value of $22.02 and a three-year restriction 
period.

At Dec. 31, 2006, there was $11 million of total unrecognized compensation related to restricted shares and 
restricted stock units.  That cost is expected to be recognized over a weighted-average period of approximately 1.7 
years.  The total fair value of the restricted shares vested and restricted stock units paid in cash during the twelve 
months ended Dec. 31, 2006, 2005 and 2004 was $40 million, $2 million and zero, respectively.  The total related 
tax benefit realized was $6 million in 2006. 

Performance Share Units 

PSUs provide for awards based on achievement of certain predetermined corporate performance goals (total 
shareholder return, return on average invested capital and operating ratio) at the end of a three-year cycle.  PSU 
grants and average grant-date fair values were 1,163,600 and $49.425 in 2006; 1,344,400 and $34.10 in 2005; and 
831,000 and $22.02 in 2004.  One-half of any PSUs earned will be paid in the form of shares of Common Stock 
with the other half to be paid in cash.

In November 2005, NS’ Board of Directors authorized the repurchase of up to 50 million shares of Common 
Stock through the end of 2015.  The timing and volume of purchases is guided by management’s assessment of 
market conditions and other pertinent facts.  Near-term purchases under the program are expected to be made with 
internally generated cash; however, future funding sources could include proceeds from the sale of commercial 
paper notes or the increase of long-term debt.  NS purchased and retired 21.8 million shares of its common stock 
under this program in 2006 at a cost of $964 million.

15.  Fair Values of Financial Instruments 

The fair values of “Cash and cash equivalents,” “Short-term investments,” “Accounts receivable” and “Accounts 
payable” approximate carrying values because of the short maturity of these financial instruments.  The fair value 
of corporate-owned life insurance approximates carrying value.  The carrying amounts and estimated fair values 
for the remaining financial instruments, excluding derivatives (see Note 16) and investments accounted for under 
the equity method in accordance with APB Opinion No. 18, consisted of the following at Dec. 31:

Quoted market prices were used to determine the fair value of marketable securities; underlying net assets were 
used to estimate the fair value of other investments.  The fair values of notes receivable are based on future 
discounted cash flows.  The fair values of debt were estimated based on quoted market prices or discounted cash 
flows using current interest rates for debt with similar terms, company rating and remaining maturity. 

Carrying amounts of marketable securities reflect unrealized holding gains of $1 million on Dec. 31, 2006, and 
less than $1 million on Dec. 31, 2005.  Sales of “available-for-sale” securities were immaterial for the years 
ended Dec. 31, 2006, 2005 and 2004; most short-term investments were redeemed at maturity. 

16.  Derivative Financial Instruments 

All derivatives are recognized in the financial statements as either assets or liabilities and are measured at fair 
value.  Changes in fair value are recorded as adjustments to the assets or liabilities being hedged in “Other 
comprehensive loss,” or in current earnings, depending on whether the derivative is designated and qualifies for 
hedge accounting, the type of hedge transaction represented and the effectiveness of the hedge.  The settlements 
of the hedges will result in the reclassification into diesel fuel expense of the related gains or losses recorded as a 
component of “Other comprehensive loss.” 

NS has used derivative financial instruments to reduce the risk of volatility in its diesel fuel costs and to manage 
its overall exposure to fluctuations in interest rates.  NS does not engage in the trading of derivatives.  
Management has determined that its derivative financial instruments qualify as either fair-value or cash-flow 
hedges, having values that highly correlate with the underlying hedged exposures, and has designated such

instruments as hedging transactions.  Credit risk related to the derivative financial instruments is considered to be 
minimal and is managed by requiring high credit standards for counterparties and periodic settlements.   

Diesel Fuel Hedging 

In 2001, NS began a program to hedge a portion of its diesel fuel consumption.  The intent of the program was to 
assist in the management of NS' aggregate risk exposure to fuel price fluctuations, which can significantly affect 
NS' operating margins and profitability, through the use of one or more types of derivative instruments.  No new 
hedges have been entered into since May 2004, and the last remaining contracts were settled in the second quarter 
of this year, bringing an end to this program. 

The goal of this hedging strategy was to reduce the variability of fuel costs over an extended period of time 
while minimizing the incremental cost of hedging. The program provided that NS would not enter into any fuel 
hedges with a duration of more than 36 months, and that no more than 80% of NS' average monthly fuel 
consumption would be hedged for any month within any 36-month period.  After taking into account the effect of 
the hedging, diesel fuel costs represented 14% of NS’ operating expenses for the year ended Dec. 31, 2006, 11% 
for the year ended Dec. 31, 2005 and 8% for the year ended Dec. 31, 2004. 

NS' fuel hedging activity resulted in decreases in diesel fuel expenses of $20 million, $148 million and 
$140 million for 2006, 2005 and 2004, respectively.  Ineffectiveness, or the extent to which changes in the fair 
value of the heating oil contracts do not offset changes in the fair values of the expected diesel fuel transactions, 
was a $1 million expense in 2006, a $5 million expense in 2005 and a $5 million benefit in 2004. 

Interest Rate Hedging 

NS manages its overall exposure to fluctuations in interest rates by issuing both fixed and floating-rate debt 
instruments, and by entering into interest rate hedging transactions to achieve an appropriate mix within its debt 
portfolio.  NS had $83 million and $116 million, or less than 2%, of its fixed rate debt portfolio hedged as of 
Dec. 31, 2006, and Dec. 31, 2005, respectively, using interest rate swaps that qualify for and are designated as fair-
value hedge transactions.  NS’ interest rate hedging activity resulted in decreases in interest expenses of $1 million, 
$2 million and $6 million for 2006, 2005 and 2004, respectively.  These swaps have been effective in hedging the 
changes in fair value of the related debt arising from changes in interest rates and there has been no impact on 
earnings resulting from ineffectiveness associated with these derivative transactions. 

Fair Values 

There were no diesel fuel derivative instruments outstanding at Dec. 31, 2006.  The fair value of NS' diesel fuel 
derivative instruments at Dec. 31, 2005, was determined based upon current market values as quoted by 
independent third party dealers.  Fair values of interest rate swaps were determined based upon the present value 
of expected future cash flows discounted at the appropriate implied spot rate from the spot rate yield curve.  Fair 
value adjustments are noncash transactions and, accordingly, are excluded from the Consolidated Statements of 
Cash Flows.  “Accumulated other comprehensive loss,” a component of “Stockholders' equity,” included 
unrealized gains of zero at Dec. 31, 2006, and $20 million (pretax) at Dec. 31, 2005, related to the fair value of 
derivative fuel hedging transactions that will terminate within twelve months of the respective dates.  Gains or 
losses actually realized were based on the fair value of the derivative fuel hedges at the time of termination.

Norfolk Southern and certain subsidiaries are defendants in numerous lawsuits and other claims relating 
principally to railroad operations.  When management concludes that it is probable that a liability has been 
incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings.  
While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future 
developments, in management's opinion, the recorded liability is adequate to cover the future payment of such 
liability and claims.  However, the final outcome of any of these lawsuits and claims cannot be predicted with 
certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant 
to results of operations in a particular year or quarter.  Any adjustments to the recorded liability will be 
reflected in earnings in the periods in which such adjustments are known. 

NS was involved in mass tort litigation proceedings arising out of historic flooding events that occurred in 
West Virginia in 2001.  In 2005, one of NS’ subsidiaries was identified as the target defendant for claims 
related to a specific sub-watershed.  During the first quarter of 2006, the parties reached a settlement with 
respect to NS’ liability in this matter.  The settlement did not have a material effect on the results of operations 
in the first quarter or for the year. 

Casualty Claims 

Casualty claims include employee personal injury and occupational claims as well as third-party claims, all 
exclusive of legal costs.  NS engages an independent consulting actuarial firm to aid in valuing its liability for 
these claims.  Job-related accidental injury and occupational claims are subject to the Federal Employers’ 
Liability Act (FELA), which is applicable only to railroads.  FELA’s fault-based system produces results that are 
unpredictable and inconsistent as compared with a no-fault workers’ compensation system.  The variability 
inherent in this system could result in actual costs being very different from the liability recorded.  While the 
ultimate amount of claims incurred is dependent on future developments, in management’s opinion, the recorded 
liability is adequate to cover the future payments of claims and is supported by the most recent actuarial study.  In 
all cases, NS records a liability when the expected loss for the claim is both probable and estimable. 

In 2005, NS recorded a liability related to the Jan. 6, 2005 derailment in Graniteville, SC.  The liability, which 
includes a current and long-term portion, represents NS’ best estimate based on current facts and circumstances.  
The estimate includes amounts related to business property damage and other economic losses, personal injury 
and individual property damage claims as well as third-party response costs.  NS’ commercial insurance policies 
are expected to cover substantially all expenses related to this derailment above NS’ self-insured retention, 
including NS’ response costs and legal fees.  Accordingly, the Consolidated Balance Sheets reflect a current and 
long-term receivable for estimated recoveries from NS’ insurance carriers.  Expenses in 2005 included 

K73 

  
  
  
  
  
  
  
  
 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
$41 million related to this incident, representing NS’ retention under its insurance policies and other uninsured 
costs.  While it is reasonable to expect that the liability for covered losses could differ from the amount recorded, 
such a change would be offset by a corresponding change in the insurance receivable.  As a result, NS does not 
believe that it is reasonably likely that its net loss (the difference between the liability and future recoveries) will 
be materially different than the loss recorded in 2005.  NS expects at this time that insurance coverage is adequate 
to cover potential claims and settlements above its self-insurance retention.  

Employee personal injury claims – The largest component of casualties and other claims expense is 
employee personal injury costs.  The actuarial firm engaged by NS provides quarterly studies to aid in valuing 
its employee personal injury liability and estimating its employee personal injury expense.  The actuarial firm 
studies NS’ historical patterns of reserving for claims and subsequent settlements, taking into account relevant 
outside influences.  The actuary uses the results of these analyses to estimate the ultimate amount of the 
liability, which includes amounts for incurred but unasserted claims.  NS adjusts its liability to the actuarially 
determined amount on a quarterly basis.  The estimate of loss liabilities is subject to inherent limitation given 
the difficulty of predicting future events such as jury decisions, court interpretations or legislative changes and 
as such the actual loss may vary from the actuarial estimate. 

Occupational claims – Occupational claims (including asbestosis and other respiratory diseases, as well as 
repetitive motion) are often not caused by a specific accident or event but rather result from a claimed exposure 
over time.  Many such claims are being asserted by former or retired employees, some of whom have not been 
employed in the rail industry for decades.  The actuarial firm provides an estimate of the occupational claims 
liability based upon NS’ history of claim filings, severity, payments and other pertinent facts.  The liability is 
dependent upon management’s judgments made as to the specific case reserves as well as judgments of the 
consulting actuarial firm in the periodic studies.  The actuarial firm’s estimate of ultimate loss includes a 
provision for those claims that have been incurred but not reported.  This provision is derived by analyzing 
industry data and projecting NS’ experience into the future as far as can be reasonably determined.  NS adjusts 
its liability to the actuarially determined amount on a quarterly basis.  However, it is possible that the recorded 
liability may not be adequate to cover the future payment of claims.  Adjustments to the recorded liability are 
reflected in operating expenses in the periods in which such adjustments become known. 

Third-party claims – NS records a liability for third-party claims including those for highway crossing 
accidents, trespasser and other injuries, automobile liability, property damage and lading damage.  The 
actuarial firm assists with the calculation of potential liability for third-party claims, except lading damage, 
based upon NS’ experience including number and timing of incidents, amount of payments, settlement rates, 
number of open claims and legal defenses.  The actuarial estimate includes a provision for claims that have 
been incurred but have not yet been reported.  Each quarter NS adjusts its liability to the actuarially determined 
amount.  Given the inherent uncertainty in regard to the ultimate outcome of third-party claims, it is possible 
that future settlement costs may differ from the estimated liability recorded. 

Environmental Matters 

NS is subject to various jurisdictions' environmental laws and regulations.  It is NS' policy to record a liability 
where such liability or loss is probable and its amount can be estimated reasonably.  Claims, if any, against 
third parties for recovery of cleanup costs incurred by NS are reflected as receivables (when collection is 
probable) on the balance sheet and are not netted against the associated NS liability.  Environmental engineers 
regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to 
liability estimates.  NS also has an Environmental Policy Council, composed of senior managers, to oversee 
and interpret its environmental policy. 

NS' Consolidated Balance Sheets included liabilities for environmental exposures in the amount of $54 million at 
Dec. 31, 2006, and $58 million at Dec. 31, 2005 (of which $12 million was accounted for as a current liability at 
Dec. 31, 2006 and 2005).  At Dec. 31, 2006, the liability represented NS' estimate of the probable cleanup and 

K74 

 
 
 
 
  
  
remediation costs based on available information at 172 known locations compared with 189 locations at Dec. 31, 
2005.  On that date, 15 sites accounted for $29 million of the liability, and no individual site was considered to be 
material.  NS anticipates that much of this liability will be paid out over five years; however, some costs will be 
paid out over a longer period. 

At some of the 172 locations, certain NS subsidiaries, usually in conjunction with a number of other parties, 
have been identified as potentially responsible parties by the Environmental Protection Agency (EPA) or similar 
state authorities under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, 
or comparable state statutes, which often impose joint and several liability for cleanup costs. 

With respect to known environmental sites (whether identified by NS or by the EPA or comparable state 
authorities), estimates of NS' ultimate potential financial exposure for a given site or in the aggregate for all 
such sites are necessarily imprecise because of the widely varying costs of currently available 
cleanup techniques, the likely development of new cleanup technologies, the difficulty of determining in 
advance the nature and full extent of contamination and each potential participant's share of any estimated loss 
(and that participant's ability to bear it), and evolving statutory and regulatory standards governing liability. 

The risk of incurring environmental liability – for acts and omissions, past, present and future - is inherent in the 
railroad business.  Some of the commodities in NS' traffic mix, particularly those classified as hazardous 
materials, can pose special risks that NS and its subsidiaries work diligently to minimize.  In addition, several NS 
subsidiaries own, or have owned, land used as operating property, or which is leased and operated by others, or 
held for sale.  Because environmental problems may exist on these properties that are latent or undisclosed, there 
can be no assurance that NS will not incur environmental liabilities or costs with respect to one or more of them, 
the amount and materiality of which cannot be estimated reliably at this time.  Moreover, lawsuits and claims 
involving these and potentially other unidentified environmental sites and matters are likely to arise from time to 
time.  The resulting liabilities could have a significant effect on financial position, results of operations or 
liquidity in a particular year or quarter. 

However, based on its assessment of the facts and circumstances now known, management believes that it has 
recorded the probable costs for dealing with those environmental matters of which NS is aware.  Further, 
management believes that it is unlikely that any known matters, either individually or in the aggregate, will have 
a material adverse effect on NS' financial position, results of operations or liquidity. 

On Oct. 19, 2006, the Pennsylvania Department of Environmental Protection (PDEP) issued an assessment of 
civil penalties against NS and filed a complaint for civil penalties with the Pennsylvania Environmental Hearing 
Board (EHB) requesting that the EHB impose civil penalties upon NS for alleged violations of state 
environmental laws and regulations resulting from a discharge of sodium hydroxide that occurred as a result of 
the derailment of a NS train in Norwich Township, Pennsylvania, on June 30, 2006.  The PDEP’s actions seek to 
impose combined penalties of $8,890,000 for alleged past violations and $46,420 per day for alleged ongoing 
violations of state environmental laws and regulations.  NS believes that the monetary penalties sought by the 
PDEP are excessive.  Accordingly, NS intends to vigorously defend the action and has appealed the fines to the 
EHB.  In addition, NS expects the Pennsylvania Fish and Boat Commission to impose a monetary penalty on NS 
for damages alleged to have been caused by this accident.  NS does not believe that the outcome of these 
proceedings will have a material effect on its financial position, results of operations, or liquidity.  

Insurance 

NS obtains on behalf of itself and its subsidiaries insurance for potential losses for third-party liability and first-
party property damages.  Specified levels of risk are retained on a self-insurance basis (up to $25 million per 
occurrence for bodily injury and property damage to third parties and $25 million per occurrence for property 
owned by NS or in NS’ care, custody or control).

Purchase Commitments 

NSR had outstanding purchase commitments of approximately $276 million primarily in connection with its 
capital programs through 2010, including 53 locomotives in 2007. 

Change-In-Control Arrangements 

Norfolk Southern has compensation agreements with officers and certain key employees that become operative 
only upon a change in control of the Corporation, as defined in those agreements.  The agreements provide 
generally for payments based on compensation at the time of a covered individual's involuntary or other specified 
termination and for certain other benefits. 

Guarantees 

In a number of instances, NS and its subsidiaries have agreed to indemnify lenders for additional costs they may 
bear as a result of certain changes in laws or regulations applicable to their loans.  Such changes may include 
impositions or modifications with respect to taxes, duties, reserves, liquidity, capital adequacy, special deposits, 
and similar requirements relating to extensions of credit by, deposits with, or the assets or liabilities of such 
lenders.  The nature and timing of changes in laws or regulations applicable to NS' financings are inherently 
unpredictable, and therefore NS' exposure in connection with the foregoing indemnifications cannot be quantified.  
No liability has been recorded related to these indemnifications.  In the case of one type of equipment financing, 
NSR's Japanese leveraged leases, NSR may terminate the leases and ancillary agreements if such a change-in-law 
indemnity is triggered.  Such a termination would require NSR to make early termination payments that would 
not be expected to have a material adverse effect on NS' financial position, results of operations or liquidity. 

NS has indemnified parties in a number of transactions for U.S. income tax withholding imposed as a result of 
changes in U.S. tax law.  In all cases, NS has the right to unwind the related transaction if the withholding cannot 
be avoided in the future.  Because these indemnities would be triggered and are dependent upon a change in the 
tax law, the maximum exposure is not quantifiable.  Management does not believe that it is likely that it will be 
required to make any payments under these indemnities. 

As of Dec. 31, 2006, certain Norfolk Southern subsidiaries are contingently liable as guarantors with respect to 
$8 million of indebtedness of an entity in which they have an ownership interest, the Terminal Railroad 
Association of St. Louis, due in 2019.  Four other railroads are also jointly and severally liable as guarantors for 
this indebtedness.  No liability has been recorded related to this guaranty.

None. 

Item 9A.  Controls and Procedures. 

Evaluation of Disclosure Controls and Procedures 

Norfolk Southern’s Chief Executive Officer and Chief Financial Officer, with the assistance of management, 
evaluated the effectiveness of NS' disclosure controls and procedures (as such term is defined in Rules 13a-15(e) 
and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of Dec. 31, 2006.  
Based on such evaluation, such officers have concluded that, as of Dec. 31, 2006, NS' disclosure controls and 
procedures were effective to ensure that information required to be disclosed in NS’ reports under the Exchange Act 
is recorded, processed, summarized and reported, within time period specified in the SEC’s rules and forms, and 
that such information is accumulated and communicated to management, including the Chief Executive Officer and 
the Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. 

Internal Control over Financial Reporting 

The management of Norfolk Southern is responsible for establishing and maintaining adequate internal control 
over financial reporting.  The Corporation’s internal control over financial reporting includes those policies and 
procedures that pertain to its ability to record, process, summarize and report reliable financial data.  Management 
recognizes that there are inherent limitations in the effectiveness of any internal control over financial reporting, 
including the possibility of human error and the circumvention or overriding of internal control.  Accordingly, 
even effective internal control over financial reporting can provide only reasonable assurance with respect to 
financial statement preparation.  Further, because of changes in conditions, the effectiveness of internal control 
over financial reporting may vary over time. 

In order to ensure that the Corporation’s internal control over financial reporting is effective, management 
regularly assesses such controls and did so most recently for its financial reporting as of Dec. 31, 2006.  This 
assessment was based on criteria for effective internal control over financial reporting set forth by the Committee 
of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.  
Based on our assessment, management has concluded that the Corporation maintained effective internal control 
over financial reporting as of Dec. 31, 2006. 

The Board of Directors, acting through its Audit Committee, is responsible for the oversight of the Corporation's 
accounting policies, financial reporting and internal control.  The Audit Committee of the Board of Directors is 
comprised entirely of outside directors who are independent of management.  The independent registered public 
accounting firm and the internal auditors have full and unlimited access to the Audit Committee, with or without 
management, to discuss the adequacy of internal control over financial reporting, and any other matters which 
they believe should be brought to the attention of the Audit Committee. 

Norfolk Southern’s management has issued a report of its assessment of internal control over financial reporting, 
and Norfolk Southern’s independent registered public accounting firm has issued a report on this assessment.  
These reports appear in Part II, Item 8 of this report on Form 10-K. 

During the fourth quarter of 2006, management has not identified any changes in NS' internal controls over 
financial reporting that have materially affected, or are reasonably likely to materially affect, NS’ internal control 
over financial reporting.

6     Of the shares remaining available for grant under plans not approved by stockholders, 36,000 are available for grant

Norfolk Southern Corporation Long-Term Incentive Plan (“LTIP”)  

Established on June 28, 1983, and approved by stockholders at their Annual Meeting held on May 10, 1984, LTIP 
was adopted to promote the success of Norfolk Southern by providing an opportunity for non-employee directors, 
officers and other key employees to acquire a proprietary interest in the Corporation.  On Jan. 23, 2001, the Board 
of Directors further amended LTIP and approved the issuance of an additional 5,000,000 shares of authorized but 
unissued Common Stock under LTIP to participants who are not officers of Norfolk Southern.  The issuance of 
these shares was broadly-based, and stockholder approval of these shares was not required.  Accordingly, this 
portion of LTIP is included in the number of securities available for future issuance for plans not approved by 
stockholders.  Also on Jan. 23, 2001, the Board amended LTIP, which amendment was approved by shareholders 
on May 10, 2001, that included the reservation for issuance of an additional 30,000,000 shares of authorized but 
unissued Norfolk Southern Common Stock.   

Pursuant to another amendment approved by stockholders on May 12, 2005, not more than 8.5 million of the 
shares remaining available for issuance under LTIP may be awarded as restricted shares, performance shares or 
restricted stock unit shares.  Cash payments of restricted stock units, stock appreciation rights and performance 
share units will not be applied against the maximum number of shares issuable under LTIP.  Any shares of 
Common Stock subject to options, performance share units or restricted stock units which are not issued as 
Common Stock will again be available for award under LTIP after the expiration or forfeiture of an award.

Non-employee directors, officers and other key employees residing in the United States or Canada are eligible for 
selection to receive LTIP awards.  Under LTIP, the Compensation Committee (Committee) may grant incentive stock 
options, nonqualified stock options, stock appreciation rights, restricted shares, restricted stock units and performance 
share units.  In addition, dividend equivalents may be awarded for options, restricted stock units and performance 
share units. The Committee may establish such terms and conditions for the awards as provided in LTIP.  

For options, the option price per share will not be less than 100% of the fair market value of Norfolk Southern's 
Common Stock on the effective date the option is granted.  All options are subject to a vesting period of at least 
one year, and the term of the option will not exceed ten years.  LTIP specifically prohibits option repricing 
without stockholder approval, except for capital adjustments.  

Performance share units entitle a recipient to receive performance-based compensation at the end of a three-year 
performance cycle based on Norfolk Southern’s performance during that three-year period.  For the 2006 
performance share unit awards, corporate performance will be measured using three equally weighted standards 
established by the committee: (1) three-year average return on average capital invested, (2) three-year average 
operating ratio and (3) three-year total return to stockholders.  Performance share units may be payable in either 
shares of Norfolk Southern Common Stock or cash. 

Restricted stock units are payable in cash or in shares of Norfolk Southern Common Stock at the end of a 
restriction period of not less than 36 months and not more than 60 months.  During the restriction period, the 
holder of the restricted stock units has no beneficial ownership interest in the Norfolk Southern Common Stock 
represented by the restricted stock units and has no right to vote the shares represented by the units or to receive 
dividends (except for dividend equivalent rights that may be awarded with respect to the restricted stock units).  
Restricted stock units will be forfeited immediately if the holder leaves the continuous employment of Norfolk 
Southern before the end of the restriction period, unless such employment is terminated by reason of retirement, 
disability or death or unless the restrictions are waived by Norfolk Southern. 

Norfolk Southern Corporation Thoroughbred Stock Option Plan 

The Board adopted the Norfolk Southern Corporation Thoroughbred Stock Option Plan (“TSOP”) on Jan. 26, 
1999, to promote the success of Norfolk Southern by providing an opportunity for nonagreement employees to 
acquire a proprietary interest in Norfolk Southern and thereby to provide an additional incentive to nonagreement 
employees to devote their maximum efforts and skills to the advancement, betterment, and prosperity of Norfolk 
Southern and its stockholders.  TSOP has not been and is not required to have been approved by stockholders.  
Six million shares of authorized but unissued Common Stock were reserved for issuance under TSOP. 

Active full-time nonagreement employees residing in the United States or Canada are eligible for selection to 
receive TSOP awards.  Under TSOP, the Compensation Committee of the Board of Directors may grant 
nonqualified stock options subject to such terms and conditions as provided in TSOP. 

The option price will not be less than 100% of the fair market value of Norfolk Southern's Common Stock on the 
effective date the options are granted.  All options are subject to a vesting period of at least one year, and the term 
of the option will not exceed ten years.  TSOP specifically prohibits option repricing without stockholder 
approval, except for capital adjustments.

Norfolk Southern Corporation Directors' Restricted Stock Plan 

The Norfolk Southern Corporation Directors' Restricted Stock Plan (“Plan”) was adopted on Jan. 1, 1994, and is 
designed to increase ownership of Norfolk Southern Common Stock by its non-employee directors so as to further 
align their ownership interest in Norfolk Southern with that of stockholders.  The Plan has not been and is not 
required to have been approved by stockholders.  Currently, a maximum of 66,000 shares of Corporation 
Common Stock may be granted under the Plan.  To make grants to eligible directors, Norfolk Southern purchases, 
through one or more subsidiary companies, the number of shares required in open-market transactions at 
prevailing market prices, or makes such grants from Norfolk Southern Common Stock already owned by one or 
more of Norfolk Southern's subsidiary companies. 

Only non-employee directors who are not and never have been employees of Norfolk Southern are eligible to 
participate in the Plan.  Upon becoming a director, each eligible director receives a one-time grant of 3,000 
restricted shares of Norfolk Southern Common Stock.  No individual member of the Board exercises discretion 
concerning the eligibility of any director or the number of shares granted. 

The restriction period applicable to restricted shares granted under the Plan begins on the date of the grant and 
ends on the earlier of the recipient’s death or six months after the recipient ceases to be a director by reason of 
disability or retirement.  During the restriction period shares may not be sold, pledged or otherwise encumbered.  
Directors will forfeit the restricted shares if they cease to serve as a director of Norfolk Southern for reasons other 
than their disability, retirement or death.
