Dear Fellow Stockholders

In the past few years, Norfolk Southern and the rest of the rail industry saw an 

unprecedented period of both traffic and revenue growth, resulting in a very strong 

financial performance and superior shareholder returns. These years of growth 

were driven by a strong economy and fundamental changes in the transportation 

marketplace — among them higher fuel costs, increased highway congestion, and 

continued shortages of long-distance truck drivers — that played to the strengths  

of our industry. 

2007 was, in my opinion, a watershed year for us in that it answered the question 

of how real and long-lasting our improved performance would be in the face of 

an economic downturn. The answer was a strong affirmation that our prospects 

remain very bright.

Railway operating revenues, income from railway operations, and diluted earnings 

per share set records, even as the downturn in housing, softness in the automotive 

sector, and increased motor carrier capacity made for a year in which our volumes 

were down 4 percent and our net income was essentially flat. 

Earnings per share increased 3 percent, driven by our re-purchase of 24 million 

shares. For most of the year and for the beginning of 2008 as well, we believed 

our shares were trading at a price that made re-purchasing a good way to return 

money to investors while providing a superior return for our remaining shareholders. 

We also increased our dividend for the sixth consecutive year, this time by an  

aggregate 41 percent, a clear sign of our confidence in Norfolk Southern’s future. 

There was a lot of other good news in 2007. Our overall service metrics improved, 

and we continued to be recognized as a leading service provider in the industry.  

But while it’s nice to be recognized, we know how much more we can still do to 

improve service, and we remain dedicated to the idea that superior service is the 

key to growing volumes and revenues, and delivering exceptional financial results.  

To reinforce that, we are for the first time making service improvement part of our 

broad-based incentive compensation program.

Despite some weakness in the economy, we continued our strong programs to 

maintain our assets and infrastructure and to add capacity for future growth. A 

great example of that growth was the announcement by ThyssenKrupp that they 

will construct a major new steel plant on our railroad near Mobile, Ala. This will  

be a significant new customer for us when it comes on line in 2010 and exemplifies 

the work that our second-to-none industrial development group, supported by 

teams of people throughout the company, can do.

The keys to this success, along with all of our other  

Like every year, 2008 will have its challenges and  

successes, are the people of Norfolk Southern. No  

opportunities, but the demand for high-quality rail

transportation will continue to be strong. It is telling

A locomotive pulls flat cars for loading at Atlanta’s Inman Yard. Over the 
next 24 hours, 83 trains will pass through Inman, one of Norfolk Southern’s 
busiest yards.   

Twenty-four hours a day, seven days a week, Norfolk Southern trains  

move across 21,000 route miles in 22 states, reaching every major  

eastern port and linking customers to markets all over the world. 

On one of those days, Oct. 23, 2007, 1,705 trains operated on the network. 

Eighty-two trains hauled 1 million tons of utility coal, enough to provide 

power for nearly every household in Virginia for a month. Seventy-six 

trains transported 51,000 new cars and trucks; others carried everything 

from wind turbines to 56 million pounds of granulated sugar.

For the 2007 annual report, we made a photographic record of some of 

what took place on Norfolk Southern that day.

In the pages that follow, we invite you to travel with Norfolk Southern for 

a day — from midnight in Atlanta to daybreak in Baltimore to sunset in 

Homer, Ill. Oct. 23, 2007, a day on which Norfolk Southern and its more 

than 30,000 employees worked hard to demonstrate their commitment  

to operate the safest and most efficient railroad in North America, day 

after day, 365 days a year.

nothing is more important than ensuring that these

By providing excellent service, Norfolk Southern is

shipments arrive safely at their destinations.  

In addition to carrying chemicals for Eastman,  

In 2007, Norfolk Southern carried about 427,000  

carloads of chemicals, serving shippers and  

receivers of petroleum products, plastics, bleaching  

compounds, industrial chemicals, and hazardous  

and nonhazardous wastes.  

Norfolk Southern also delivers coal, which the  

company uses in an innovative coal gasification  

process at its Kingsport complex. The carbon- 
capturing technology transforms coal into chemical  

raw materials and energy. 

Trains carrying ethanol arrive and unload at the Thoroughbred Bulk  
Transfer Terminal in Baltimore. Ethanol is transferred from trains to trucks 
and delivered to gasoline blending terminals throughout the mid-Atlantic.

U.S. production of ethanol is soaring and producers rely on Norfolk Southern to 

transport it. Because of its water-soluble nature, ethanol does not lend itself to  

pipeline movements, making rail the most efficient mode of transport.

Norfolk Southern moves more than a billion gallons of ethanol a year from plants 

west of the Mississippi to eastern destinations. Eleven additional plants now being 

built on the Norfolk Southern line and on connecting short-line railroads will  

produce another 850 million gallons.

Most of the ethanol Norfolk Southern handles moves through terminals, where it is 

stored and blended with gasoline. Baltimore’s Thoroughbred Bulk Transfer Terminal 

is one of 20 ethanol terminals that Norfolk Southern serves. With new terminals  

set to open next year in Florida, Georgia, New Jersey, North Carolina, and Virginia,  

Norfolk Southern will be able to provide even more efficient service to customers, 

and will help meet the growing demand for ethanol.

and nonhazardous wastes.  

Norfolk Southern also delivers coal, which the  

company uses in an innovative coal gasification  

process at its Kingsport complex. The carbon- 
capturing technology transforms coal into chemical  

raw materials and energy. 

Trains carrying ethanol arrive and unload at the Thoroughbred Bulk  
Transfer Terminal in Baltimore. Ethanol is transferred from trains to trucks 
and delivered to gasoline blending terminals throughout the mid-Atlantic.

U.S. production of ethanol is soaring and producers rely on Norfolk Southern to 

transport it. Because of its water-soluble nature, ethanol does not lend itself to  

pipeline movements, making rail the most efficient mode of transport.

Norfolk Southern moves more than a billion gallons of ethanol a year from plants 

west of the Mississippi to eastern destinations. Eleven additional plants now being 

built on the Norfolk Southern line and on connecting short-line railroads will  

produce another 850 million gallons.

Most of the ethanol Norfolk Southern handles moves through terminals, where it is 

stored and blended with gasoline. Baltimore’s Thoroughbred Bulk Transfer Terminal 

is one of 20 ethanol terminals that Norfolk Southern serves. With new terminals  

set to open next year in Florida, Georgia, New Jersey, North Carolina, and Virginia,  

Norfolk Southern will be able to provide even more efficient service to customers, 

and will help meet the growing demand for ethanol.

A train loaded with coiled steel makes its way from an AK Steel facility in  
Middletown, Ohio, to AK Steel’s Rockport Works in Rockport, Ind. Norfolk Southern 
hauls more than 40,000 carloads of steel a year to and from Rockport Works.

Norfolk Southern continues to lead the industry in the transportation of steel  

and other metals. The railroad serves 19 integrated mills, 17 minimills, more  

than 38 major steel processors, and more than 75 steel distribution facilities.    

Built in 1998, AK Steel’s Rockport Works steel finishing facility was one of the  

largest industrial development projects in the railroad’s history. Norfolk Southern 

runs a daily unit train of semifinished steel from AK’s Middletown, Ohio, complex  

to its Rockport plant. From there, the railroad moves finished steel to automotive 

assembly plants and appliance manufacturers. 

Norfolk Southern is working with German steel manufacturer ThyssenKrupp to  

support a new processed steel plant being built in Mount Vernon, Ala., in what is 

expected to be Norfolk Southern’s largest industrial development project ever  

and one of the largest new plant investments in the United States.  

For more than two years, a team of Norfolk Southern experts in marketing, industrial 

development, finance, ports, and transportation worked with ThyssenKrupp and 

state and local authorities to select the site for the state-of-the-art plant. The facility 

will use import slabs from ThyssenKrupp’s Brazilian slab mill to produce sheet steel 

for the automotive and appliance markets. When production begins in 2010, Thyssen-

Krupp expects to produce more than 5 million tons of processed steel per year. 

Norfolk Southern cars carrying John Deere tractors bound for export  
and sale to customers overseas move through Altoona. Norfolk Southern  
transports thousands of tractors a year from the John Deere plant in  
Waterloo, Iowa, to the port of Baltimore.   

Anticipating a growing international demand for U.S.-made tractors and other heavy machinery, Norfolk  

Southern five years ago began to put a transportation plan in place to handle the traffic. Today, Norfolk  

Southern moves tractors, combines, and other agricultural equipment to the port of Baltimore for John Deere,  

Case New Holland, and other customers. Norfolk Southern also moves industrial machinery to the port of  

Savannah, Ga., for Caterpillar. Since 2002, annual revenue from movements of heavy machinery, mainly  

from the Midwest, has increased eightfold.

Workmen record track dimensions inside the Cowan Tunnel — one of 28 
tunnels where vertical clearances will be raised to accommodate double-
stacked container traffic from the East Coast to the Midwest. 

Aging highways, increasing roadway congestion, and 

surging global trade will require new investment in   

rail capacity to keep the nation’s economy growing.  

To ensure better service for customers, Norfolk  

Southern is partnering with federal, state, and local 

governments to design and build major infrastructure 

projects that will provide a safer, higher-capacity,  

and more fuel-efficient transportation network.

In October 2007, Norfolk Southern began the first 

phase of tunnel work on the Heartland Corridor in 

partnership with the federal government and the  

states of Virginia, Ohio, and West Virginia. In the photo  

at right, Norfolk Southern’s Bob Billingsley inspects 

track outside the Cowan Tunnel. 

In early 2008, work will begin on three other tunnels  

in Virginia and on eight tunnels in West Virginia. In  

addition, the company plans to increase clearances  

on more than a dozen bridges, signals, and sets of  

overhead wires in those states and Ohio. When the 

project is completed in 2010, trains carrying freight in 

double-stacked containers will be able to cut more

At the Whitaker Intermodal Terminal, a crane transfers a container from truck  
to rail. Over the last five years, intermodal has been the fastest-growing part  
of Norfolk Southern’s business.  

A growing world population, an increasingly global 

economy, mounting congestion on U.S. highways, and 

the need for improved fuel efficiency — all are factors 

that are expected to help Norfolk Southern’s intermodal 

business continue to grow. In 2007, volumes fell slightly 

because of slowing housing and automotive markets and 

excess truck capacity. In the future, Norfolk Southern 

expects increasing demand for transportation of  

containerized freight as Asian economies continue to 

develop, the United States returns to a pattern of robust 

consumption, and U.S. exports continue to increase.

Anticipating that growth, Norfolk Southern is  

working continually to improve service and expand  

intermodal capacity.

In 2007, Norfolk Southern joined with Union Pacific  

to introduce a shorter and faster route between Los 

Angeles and the Southeast. The new route moves  

over the Meridian Speedway and through Shreveport, 

La. It is almost 150 miles shorter than the previous  

route and faster than any other service offering in the 

market. The two railroads plan to expand this already-

reliable service and further reduce transit times.  

Improvements to the Meridian Speedway, a joint venture 

between Norfolk Southern and Kansas City Southern, 

will create additional capacity that is expected to allow 

the route to handle international traffic as well.

syrup and various feed ingredients to biodiesel  

products and ethanol. 

The country’s increasing demand for ethanol and 

other renewable fuels is driving business for  

Norfolk Southern — in the transport of ethanol as  

well as the corn and soybeans needed for its  

production, and the fertilizer to grow these crops.

Oct. 23, 2007. It was one day in the operation of  

Norfolk Southern — a day on which the railroad 

moved tons of commodities across its network  

without a single reportable employee injury. While 

only a snapshot, the success of that one day  

multiplied by 365 captures a picture of the superior 

performance and strong financial results achieved  

by the company in 2007. It was a good year for the 

Thoroughbred, a year that saw increased new  

business, increased revenue, and increased  

dividends; a year in which the railroad operated  

more efficiently than ever before on its way to  

becoming the safest, most customer-focused, and 

successful transportation company in the world.

Bushels of corn are loaded from a grain elevator into Norfolk Southern cars. 
When assembled, the 75-car train will make its way to Forsyth, Ga., carrying 
295,112 bushels of corn for poultry feed.

A core part of Norfolk Southern’s agriculture business 

is the shipment of corn from the Midwest to the  

animal feeding, processing, and export markets in  

the East and Southeast. In the Midwest, Norfolk 

Southern also runs a brisk business carrying 

corn and soybeans from grain elevators to large  

processing plants that make everything from corn 

syrup and various feed ingredients to biodiesel  

products and ethanol.

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.  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, 2007, 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) (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 
in print to any shareholder who requests them:

RAILWAY OPERATING REVENUES -- NS' total railway operating revenues were $9.4 billion in 2007.  See 
the financial information by traffic segment in Part II, Item 7, “Management’s Discussion and Analysis of 
Financial Condition and Results of Operations.” 

COAL TRAFFIC -- Coal, coke and iron ore -- most of which is bituminous coal -- is NS' railroads' largest 
commodity group as measured by revenues.  The railroads handled a total of 186.0 million tons in 2007, most of 
which originated on NS' lines in West Virginia, Virginia, Pennsylvania and Kentucky.  Revenues from coal, coke 
and iron ore accounted for about 25% of NS' total railway operating revenues in 2007. 

Total coal handled through all system ports in 2007 was 34.1 million tons.  Of this total, 13.4 million tons 
(including coastwise traffic) moved through Norfolk, Virginia, 2.9 million tons moved through the Baltimore 
Terminal, 10.9 million tons moved to various docks on the Ohio River, and 6.9 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, Chrysler, 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 2007, 142 million tons of general merchandise freight, or approximately 67% 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 2007 were 2.8 million, the revenue from which accounted for 
55% of NS’ total railway operating revenues in 2007. 

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 
2007 were 3.1 million, the revenues from which accounted for 20% 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 2007, 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.  The 
STB has not made its revenue adequacy determination for the year 2006.  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.

Capital spending and maintenance programs are and have been designed to assure the ability to provide safe, 
efficient and reliable transportation services.  For 2008, NS has budgeted $1.43 billion of capital expenditures.  
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.  Through Dec. 31, 2007, 
NS has contributed $240 million, 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.”

Between 1988 and 2000, about 29,000 coal cars were rebodied.  As a result, the remaining serviceability of the 
freight car fleet is greater than may be inferred from the high percentage of freight cars built in earlier years. 

Ongoing freight car and locomotive maintenance programs are intended to ensure the highest standards of safety, 
reliability, customer satisfaction and equipment marketability.  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 $389 million as of Dec. 31, 2007, and $534 million as of Dec. 31, 2006. 

Track Maintenance - Of the approximately 38,000 total miles of track operated, NS had responsibility for 
maintaining about 29,300 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 2007.

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 15,900 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 258 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 

K10 

  
  
  
  
  
  
  
  
 
 
 
  
  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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, includes exemptions of intermodal business (trailer-on-flat-car, container-on-flat-car), 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 87% of NS' freight revenues come from 
either exempt traffic or traffic moving under transportation contracts. 

Efforts were made in 2007 to re-subject the rail industry to unwarranted federal economic regulation and such 
efforts are expected to continue in 2008.  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 continue to 
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 
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. 

SECURITY OF OPERATIONS - NS has taken significant steps to provide enhanced security for the NS rail 
system.  In particular, NS has developed and implemented a comprehensive security plan that is modeled on and 
was developed in conjunction with the security plan prepared by the Association of American Railroads (AAR) 
post September 11, 2001.  The AAR Security Plan defines four Alert Levels and details the actions and 
countermeasures that are being applied across the railroad industry, as the terrorist threat increases or decreases.  
The Alert Level actions include countermeasures that will be applied in three general areas: (1) operations 
(including transportation, engineering, and mechanical); (2) information technology and communications; and (3) 
railroad police.  Although security concerns preclude public disclosure of its contents, the NS Departmental 
Security Plan outlines the protocol within NS for all concerned to be notified of AAR Alert Level changes.  All 
NS Operations Division employees are advised by their supervisors or train dispatchers, as appropriate, of any 
change in Alert Level and any additional responsibilities they may incur due to such change. 

The NS plan also effectively addresses and complies with Department of Transportation security regulations 
pertaining to training and security plans with respect to the transportation of hazardous materials.  Among more 
focused elements of the plan, security awareness training is given to all railroad employees who directly affect 
hazardous material transportation safety, and this training is integrated into recurring hazardous material training 
and re-certification programs.  Toward that end, NS, working closely with the National Transit Institute at Rutgers 
University, developed a four-module uniform national training program.  More in-depth security training has been 
given to those select NS employees who have been given specific security responsibilities, and additional, 

K11 

  
  
  
  
  
 
 
location-specific security plans have been developed for certain metropolitan areas and each of six port facilities 
served by NS.  With respect to the ports, each facility plan has been approved by the applicable Captain of the 
Port and subject to inspection by the U.S. Coast Guard.    

Additionally, NS engages in close and regular coordination with numerous federal and state agencies, including the 
U.S. Department of Homeland Security (DHS), the Transportation Security Administration (TSA), the Federal 
Bureau of Investigation (FBI), the Federal Railroad Administration (FRA), the U.S. Coast Guard, U.S. Customs and 
Border Protection and various state Homeland Security offices.  As one notable example, an NS Police Special 
Agent, under the auspices of the AAR, has been assigned to the National Joint Terrorism Task Force (NJTTF) 
operating out of FBI Headquarters in Washington, D.C. to represent and serve as liaison to the North American rail 
industry.  This arrangement improves logistical flow of vital security and law enforcement information with respect 
to the rail industry as a whole, while having the post filled by an NS Special Agent has served to foster a strong 
working relationship between NS and the FBI.  NS also has become a member of the Customs-Trade Partnership 
Against Terrorism (C-TPAT) program sponsored by U.S. Customs.  C-TPAT allows NS to work closely with U.S. 
Customs and its customers to develop measures that will help ensure the integrity of freight shipments moving on 
NS, particularly those moving to or from a foreign country.  Based on participation in C-TPAT, NS has ensured that 
its plan meets all current applicable security recommendations made by U.S. Customs.   

Similarly, NS is guided in its operations by various supplemental security action items issued by DHS and U.S. 
Department of Transportation (DOT), U.S. Coast Guard Maritime Security requirements, as well as voluntary 
security action items developed in collaboration with TSA, DOT, and the freight railroads in 2006.  Many of the 
action items are based on lessons learned from DHS and DOT security assessments of rail corridors in High 
Threat Urban Areas (HTUA) begun in 2004.  Particular attention is paid to: (1) the establishment of secure 
storage areas for rail cars carrying toxic-by-inhalation (TIH) materials; (2) the expedited movement of trains 
transporting rail cars carrying TIH materials; (3) the minimization of unattended loaded tank cars carrying TIH 
materials; and (4) cooperation with federal, state, local and tribal governments to identify, through risk 
assessments, those locations where security risks are the highest.  These action items and NS’ compliance 
initiatives are outlined in the various departmental sections of the NS Departmental Security Plan. 

In 2007, through participation in the Transportation Community Awareness and Emergency Response 
(TRANSCAER) Program, NS provided rail accident response training to approximately 5,000 emergency 
responders, such as local police and fire personnel, representing over 22,000 man-hours of emergency response 
training.  NS’ other training efforts throughout 2007 included participation in a major security drill with Amtrak 
and the State of Delaware in New Castle County, as well as coordinating table-top exercises involving the 
“staged” release of TIH shipments with various local, state, and federal agencies.  NS also has ongoing programs 
to sponsor local emergency responders at tank car emergency response training programs conducted at the AAR 
Transportation Technology Center in Pueblo, Colorado, and its annual TRANSCAER Whistle-Stop train makes 
stops in numerous cities, its special training cars serving as a resource to an audience of nearly 1,000 emergency 
responders annually.  

Improvements in equipment design also are expected to play a role in enhancing rail security.  The AAR has 
developed new tank car specifications for chlorine and anhydrous ammonia which are scheduled to become 
effective on March 31, 2008.  In the near future, the FRA is also expected to issue a proposed regulation 
addressing the redesign of pressurized tank cars used for the transportation of TIH gases and liquids.  A 
consortium of chemical companies is also studying improvements in tank car head, shell, fittings, and thermal 
protection in order to improve the survivability of current tank cars.

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 STB, which has jurisdiction over some 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.  In addition, Congress could 
enact re-regulation legislation.  Economic re-regulation of the rail industry by Congress 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 in the future on NS’ financial position, results of operations or liquidity in a 
particular year or quarter.  

Railroads are subject to safety and security regulation by the DOT and the DHS, which regulate most aspects of 
NS’ operations.  Proposed amendments to federal rail safety statutes, if enacted, could add significantly to 
operating costs and increase the number of employees NS and other railroads employ.  In addition, NS’ failure to 
comply with applicable laws and regulations could have a material adverse effect on NS. 

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. 

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 
would give federal regulators increased authority to conduct investigations and levy substantial fines and 
penalties in connection with railroad accidents.  Under provisions enacted in August 2007, federal regulators are 
required to prescribe new regulations governing railroads’ transportation of hazardous materials, including 
annual routing analyses, security risk assessments and employee security training.  Regulations proposed in late 
2006 by DHS mandating chain of custody and security measures likely will cause service degradation and 
higher 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 in a particular year or quarter.  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.  

K13 

 
 
 
 
 
  
 
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 and locomotive availability, data exchange and communications, reciprocal switching, 
interchange and trackage rights.  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 in a particular year or quarter.  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 
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, commercial disputes, freight loss and other property damage, and other matters.  Job-related 

K14 

  
  
 
  
 
 
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 and above $1 billion per occurrence for bodily 
injury and property damage to third parties and $25 million and above $175 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 about 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 adversely 
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 3.  Legal Proceedings. 

As of Feb. 14, 2008, 28 antitrust class actions have been filed against NS and other Class 1 railroads in various 
Federal district courts regarding fuel surcharges.  On November 6, 2007, these actions were consolidated in the 
District of Columbia by the Judicial Panel on Multidistrict Litigation.  NS believes the allegations in the 
complaints are without merit and intends to vigorously defend the cases.  In addition, NS received a subpoena 
from a state grand jury on July 13, 2007, requesting documents and materials relating to the setting of fuel 
surcharges.  NS is cooperating with the state in its investigation.  NS does not believe that the outcome of these 
proceedings will have a material effect on its financial position, results of operations, or liquidity. 

On November 30, 2007, NS received notice from the United States Department of Justice (DOJ) that the DOJ is 
prepared to bring an action against NS for alleged violations of federal environmental laws resulting from the 
discharge of chlorine and oil that occurred as a result of the Jan. 6, 2005 derailment in Graniteville, SC, including 
claims for civil penalties as well as injunctive relief.  The notice further indicates that the State of South Carolina 
may also join in any action against NS.   NS is in discussions with the DOJ in an effort to settle the DOJ's claims.  
NS does not believe that the resolution of these claims will have a material adverse effect on its 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.  PDEP’s actions sought to 
impose combined penalties of $8,890,000 for alleged past violations and $46,420 per day for alleged continuing 
violations of state environmental laws and regulations.  NS appealed the fines to the EHB.  The Pennsylvania Fish 
and Boat Commission sought financial restitution for damages alleged to have been caused by this accident.  In 
addition, the Pennsylvania Attorney General and the McKean County District Attorney filed three misdemeanor 
charges for alleged violations of state environmental and aquatic resource protection laws and regulations.  NS 
has entered into a settlement agreement with all Commonwealth of Pennsylvania parties, pursuant to which all 
claims by the Commonwealth for civil liability resulting from the derailment and spill were resolved, with NS 
agreeing to pay approximately $7.35 million in restitution to compensate for all natural resource damages and the 
agencies’ response costs caused by the derailment and spill.  NS has also pled no contest to the three 
misdemeanor charges and has paid fines in the amount of $250,000 to resolve them.

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. 

2003 discontinued operations relate to the 1998 sale of the common stock of motor carrier subsidiary, North 
American Van Lines, Inc.  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. 

2003 net income 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. 

2003 long-term debt excludes notes payable to Conrail of $716 million.

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’ 2007 results reflected softness in the overall economy that resulted in reduced traffic volumes.  Despite this, 
railway operating revenues increased slightly as improved average revenue per unit offset the volume declines.  
Railway operating expenses were about even, resulting in a railway operating ratio (a measure of the amount of 
revenues consumed by operating expenses) of 72.6%, which improved modestly from 2006. 

Cash provided by operating activities exceeded $2 billion for the third consecutive year and, along with a 
reduction in cash and short-term investment balances, provided funding for increased capital expenditures, 
significant share repurchases and higher dividends. 

Looking ahead, NS expects revenues to continue to grow, reflecting higher average revenue per unit and modestly 
higher traffic volume, particularly later in 2008 provided the overall economy improves.  NS plans to continue to 
improve service and maintain a market-based approach to pricing. 

During 2007, NS purchased and retired 23.6 million shares of NS common stock at a total cost of $1.2 billion 
under the share repurchase program approved by the Board of Directors on Nov. 22, 2005.  The Board of 
Directors amended the program in March 2007 and authorized the repurchase of up to 75 million shares of NS 
common stock through Dec. 31, 2010.  In total, NS has purchased and retired 45.3 million shares under this 
program at a total cost of $2.2 billion. 

SUMMARIZED RESULTS OF OPERATIONS 

2007 Compared with 2006 

Net income in 2007 was $1.5 billion, down $17 million, or 1%, compared with 2006.  Diluted earnings per share 
were $3.68, up $0.11, or 3%, reflecting fewer shares outstanding as a result of NS’ share repurchase program (see 
Note 13).  The decrease in net income was primarily due to higher income taxes and lower non-operating items 
that offset higher income from railway operations.  Railway operating revenues increased $25 million, as higher 
average revenue per unit overshadowed lower traffic volumes.  Railway operating expenses decreased $3 million, 
principally due to lower volume-related expenses that offset higher fuel expense. 

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 fuel prices and increased 
compensation and benefit costs.

Revenues increased $25 million in 2007 and $880 million in 2006.  Automotive revenue in 2007 included 
$26 million related to a contract volume settlement.  As shown in the following table, the increase in 2007 was 
due to higher average revenue per unit that more than offset decreased traffic volumes, whereas the 
improvement in 2006 was the result of increased average revenue per unit and higher traffic volumes.

Both comparisons reflect large increases in average revenue per unit, a result of higher rates.  In 2006 about 
40% of the revenue increase was attributable to higher fuel surcharges.  Traffic volume decreased in 2007, 
reflecting declines in all commodity groups except agriculture/consumer products/government, and chemicals.  
In 2006, traffic volume rose 1%, principally due to higher intermodal and metals/construction shipments. 

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.  During the second quarter, NS 
discontinued assessing fuel surcharges on its published (non-intermodal) public rates.  Future adjustments to 
public prices will reflect ongoing market conditions.  NS does not expect that compliance with the new STB 
regulations will have a material effect on its financial condition, results of operations or liquidity.  The traffic 
moving under these tariffs and public quotes comprised less than 10% of Norfolk Southern’s total revenue base.

COAL revenues decreased $15 million, or 1%, compared with 2006, as a 2% reduction in tonnage handled more 
than offset a 3% increase in average revenue per unit.  Carloads declined 3%, a higher percentage than the change 
in tonnage handled because of increased average tonnage per car.  Coal represented 25% of NS’ revenues in 2007, 
and 78% of shipments handled originated on NS’ lines.  As shown in the following table, decreased shipments of 
utility and domestic metallurgical coal more than offset higher export and industrial shipments.

Coal revenues in 2006 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 a $55 million benefit 
from coal rate settlements in the second quarter of 2005.  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 and domestic metallurgical coal 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 second quarter of 2007, the Virginia Supreme Court issued a decision that remanded the case to the 
trial court on the grounds that neither of its prior decisions constituted a final 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. 

Utility coal tonnage decreased 4%, compared with 2006, reflecting high stockpile levels (particularly in the 
Southeast) that led to reduced shipments, despite fairly strong electric generation (up 4%) in the NS service 
region.  In addition, the temporary closure of a major coal mine as well as the loss of business to barge 
transportation contributed to the decline. 

In 2006, 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. 

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. 

In 2008, demand for utility coal is expected to be mixed, with declining utility inventories in the Northeast 
stimulating growth but above normal stockpiles in the Southeast mitigating the growth. 

Domestic metallurgical coal, coke and iron ore tonnage decreased 14% in 2007 compared with 2006.  The 
decrease was primarily due to coke furnace outages, mine production outages and reduced spot iron ore traffic.

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. 

In 2008, domestic metallurgical coal, coke and iron ore demand is expected to be comparable to 2007 for the first 
half of the year; however, demand is expected to increase in the second half due to plant expansions. 

Export coal tonnage in 2007 increased 25% compared to 2006, primarily due to increased demand reflecting a 
lower valued dollar as well as loading delays at Australian ports.  Norfolk volume increased by approximately 
26,000 cars, or 25%, and Baltimore volume was up approximately 4,500 cars, or 19%. 

In 2006, export coal tonnage decreased 15% 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 2008, export coal tonnage is expected to increase, reflecting increased global demand. 

Other coal tonnage (principally steam coal shipped to industrial plants) increased 6% versus 2006, primarily due 
to new business and stronger demand.  In 2006, other coal tonnage decreased 3% versus 2005, primarily due to 
plant closures and mine production problems. 

GENERAL MERCHANDISE revenues increased $90 million, or 2%, in 2007 compared with 2006, as a 6% 
increase in average revenue per unit, reflecting continued market-based pricing in all groups, more than offset a 
4% decline in traffic volume.  Revenue in 2007 included $26 million related to a volume-related contract 
settlement with an automotive customer. 

In 2006, general merchandise revenues increased $520 million, or 11%, 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. 

Chemicals revenue increased 8% compared with 2006, reflecting higher rates in all groups.  Traffic volume 
rose modestly as more shipments of industrial intermediates offset fewer shipments in the petroleum, 
miscellaneous chemicals and plastics markets, which continued to reflect weakness in housing-related demand. 

In 2006, chemicals revenues 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 2008, chemicals revenue is expected to improve, principally due to increased average revenue per unit as 
volumes are expected to be comparable to 2007. 

Metals and construction revenue decreased 2% in 2007 as a 5% increase in average revenue per unit that 
resulted from higher rates was more than offset by the effects of a 6% decrease in traffic volume.  The decline in 
volume was principally due to lower iron, steel and coil shipments and reduced demand for construction 
materials, both reflecting the soft automotive and housing sectors. 

In 2006, metals and construction revenue increased 19% and traffic volume increased 5% compared with 2005 as 
declines in the fourth quarter were offset by higher volumes through the rest of the year.  Revenue per unit rose 

K25 

 
 
 
 
 
 
 
 
 
 
 
 
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 2008, metals and construction revenues are expected to grow as a result of higher traffic volumes, principally 
due to new business, and improved average revenue per unit.  However, growth could be somewhat dampened by 
the continued softness of the automotive and housing markets. 

Agriculture, consumer products and government revenue increased 5% in 2007 compared with 2006.  The 
revenue improvement resulted from higher average revenue per unit, which reflected higher rates.  Traffic volume 
rose modestly as more corn, fertilizer and ethanol shipments were mitigated by less government and consumer 
product volume. 

In 2006, agriculture, consumer products and government revenue increased 19% and traffic volume increased 4% 
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. 

Agriculture revenue is expected to continue to grow in 2008, benefiting from increasing demand for biofuel 
products including corn, soybeans and ethanol, as well as higher rates.  However, lower volumes in consumer 
products are expected to partially offset this growth. 

Automotive revenues were flat in 2007 compared with 2006 as lower traffic volumes offset higher average revenue 
per unit.  Revenue in 2007 included a $26 million volume-related contract settlement.  Volume decreased 5%, 
reflecting softness in demand for vehicles as well as parts, and the closure in June 2007 of an NS-served plant. 

In 2006, automotive revenues declined 2% compared with 2005 as lower volumes offset increased average 
revenue 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.  Reduced production at Honda and BMW also contributed to the 
volume decrease. 

For 2008, automotive revenues are expected to be lower, reflecting continued production cutbacks and 
weak demand. 

Paper, clay and forest products revenue decreased 3% in 2007 compared with 2006 as the effects of higher 
average revenue per unit were more than offset by an 8% decrease in traffic volume reflecting the continued 
housing slowdown and decline in conventional paper markets. 

In 2006, paper, clay and forest products revenue increased 11% compared with 2005 due to higher average 
revenue 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 2008, paper, clay and forest products revenues are expected to be about even as growth in waste and debris 
transportation and higher revenue per unit are expected to be tempered by continued weakness in housing-
related markets. 

INTERMODAL revenues decreased $50 million, or 3%, compared with 2006, as a 4% reduction in traffic 
volumes offset a 2% increase in average revenue per unit.  Truckload volume decreased 10% compared with 

K26 

 
 
 
 
 
 
 
 
 
 
 
2006 and domestic intermodal marketing companies (IMC) volume declined 4%.  Traffic volume for Triple 
Crown Services Company (Triple Crown), a service with rail-to-highway trailers, dropped 3%.  The declines 
for truckload, IMC and Triple Crown were primarily due to lower national demand for dry van shipments 
resulting from continued weakness in the housing and automotive markets and increased over-the-road 
competition.  International traffic volume decreased 4% reflecting reduced shipments of empty containers and 
less inland rail transportation of West Coast port traffic, which offset volume growth from East Coast port 
traffic.  Premium business, which includes parcel and LTL (less-than-truckload) carriers, was up 2% 
reflecting gains in parcel shipments that offset modest declines in LTL shipper traffic. 

In 2006, 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.  Truckload volume increased 8% reflecting continued expansion of business with 
traditional truckload companies.   IMC volume declined 9%, a result of declines in the housing, construction and 
automotive markets.  Triple Crown Services Company had flat volume compared with 2005 as higher consumer 
product shipments were offset by weaker automotive-related shipments.  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.  Premium business was down 3% as lower LTL shipper traffic 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. 

For 2008, intermodal revenue is expected to show improvement bolstered by higher average revenue per unit and 
modest improvement in volumes. 

Railway Operating Expenses 

Railway operating expenses in 2007 were $6.8 billion, about even with expenses in 2006, which were up 
$440 million compared to 2005.  The 2007 comparison reflected volume-related decreases offset by higher fuel 
expense.  The increase in 2006 was due to higher fuel prices and increased compensation and benefits. 

The railway operating ratio, which measures the percentage of railway operating revenues consumed by railway 
operating expenses, improved to 72.6% in 2007, compared with 72.8% in 2006 and 75.2% in 2005. 

The following table shows the changes in railway operating expenses summarized by major classifications (prior 
year amounts have been reclassified to conform to the current year presentation).

Compensation and benefits, which represents 37% of total railway operating expenses, decreased $85 million, 
or 3%, compared with 2006, primarily due to lower incentive compensation (down $48 million), lower volume-
related payroll (down $37 million), the absence of the prior year retirement and waiver agreements with former 
executives as well as the cost of the regular stock-based grant to the former Chief Executive Officer ($24 million), 
lower stock-based compensation (down $13 million), and lower payroll taxes (down $12 million), that were 
partially offset by increased wage rates (up $27 million) and higher medical costs (up $27 million). 

In 2006, compensation and benefits increased $144 million, or 6%, compared with 2005.  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.  The remaining increase was attributable to increased salaries and wages (up $44 million), 
higher health and welfare benefit costs (up $29 million), retirement and waiver agreements entered into in the first 
quarter as well as the cost of the regular stock-based grant to the former chief executive officer who retired (up 
$24 million), and higher payroll taxes (up $17 million).   

NS employment averaged 30,806 in 2007 compared with 30,541 in 2006 and 30,294 in 2005.  The increased 
number of employees was almost exclusively in operating department personnel to meet service needs, as well as 
to prepare for 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. 

Purchased services and rents includes 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 decreased $27 million, or 2%, in 2007 compared to 2006, but increased $31 million, or 2%, 
in 2006 compared to 2005.  The decline in 2007 was principally due to lower equipment rents, while the 2006 
increase reflected increased maintenance activities. 

Purchased services costs were $1,172 million in 2007, $1,165 million in 2006 and $1,142 million in 2005.  In 
2007, higher expenses for maintenance activities were largely offset by volume-related declines.  The increase in 
2006 reflected higher intermodal volume-related expenses. 

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, amounted to $379 million, $413 million 
and $405 million for 2007, 2006 and 2005, respectively.  The decrease in 2007 was principally due to lower 
shipment volumes.  The increase in 2006 was primarily due to a reduction in rents received on automotive 
equipment as a result of decreased shipments. 

Fuel expense, which includes the cost of locomotive fuel as well as other fuel used in railway operations, 
increased $74 million, or 7%, in 2007 compared with 2006, and increased $274 million, or 33%, in 2006 
compared with 2005.  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).  The increase in 2007 reflected a 9% increase in the price per gallon of locomotive fuel as well as the 
absence of hedge benefits offset in part by a 4% decline in consumption.  Expense in 2006 included hedge 
benefits of $20 million compared with benefits of $148 million in 2005, and reflected a 13% rise in the average 
price per gallon with a 1% 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 500 million gallons of locomotive diesel fuel per year.

Depreciation expense increased $37 million, or 5%, in 2007 compared to 2006, but decreased $36 million, or 
5%, in 2006 compared with 2005.  In both years, substantial capital investments and improvements resulted in 
higher depreciation expense.  The net decrease in 2006 reflected the results of an equipment depreciation study 
and an analysis of the assets received in the Conrail Corporation Reorganization completed in 2006. 

Materials and other expenses (including the estimates of costs related to personal injury, property damage and 
environmental matters) decreased $2 million in 2007 compared with 2006, but increased $27 million, or 3%, in 
2006 compared to 2005, as shown in the following table.

The decline in 2007 was primarily due to lower derailment and personal injury costs, offset in part by higher 
property and other taxes, and increased materials costs for maintenance activities. 

The increase in 2006 reflected increased locomotive and freight car repair costs due to more maintenance activity 
related to higher usage from increased traffic volumes coupled with the age of the fleet, as well as higher expenses 
arising from derailments and insurance costs.  These increases were partially offset by the absence of $38 million of 
costs associated with the 2005 derailment in Graniteville, South Carolina, and an unfavorable jury verdict in an 
employee injury case. 

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.  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 
previously recorded.  NS expects at this time that insurance coverage is adequate to cover potential claims and 
settlements above its self-insurance retention.  

The largest component of casualties and other claims expense is personal injury costs.  Cases involving 
occupational injuries comprised about 60% of total employee injury cases resolved and about 40% 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. 
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. 

K29 

 
 
 
 
 
 
 
 
 
 
 
  
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 2008. 

Other Income – Net 

Other income – net was $93 million in 2007, $149 million in 2006 and $74 million in 2005 (see Note 2).  The 
decrease in 2007 reflected lower interest income ($31 million), higher expenses associated with synthetic fuel-
related tax credit investments ($15 million) and lower returns from corporate-owned life insurance ($15 million) 
that combined to offset higher equity in earnings of Conrail ($20 million). 

NS has membership interests representing ownership in companies that owned and operated facilities that 
produced synthetic fuel from coal.  In addition, NS purchased two facilities that produced synthetic fuel from 
coal in 2007.  The production of synthetic fuel resulted in tax credits as well as expenses related to the 
investments.  The expenses are recorded as a component of “Other income – net,” and the tax credits, as well as 
tax benefits related to the expenses, are reflected in “Provision for income taxes” (see discussion below). 

Results in 2006 reflected lower expense associated with tax credit investments primarily due to synthetic fuel 
related investments, greater interest income, and higher returns from corporate-owned life insurance, that were 
partially offset by lower equity in Conrail earnings.   

Income Taxes 

Income tax expense in 2007 was $773 million for an effective rate of 35%, compared with effective rates of 34% 
in 2006 and 25% in 2005.  The increase in the rate for 2007 largely resulted from Illinois tax legislation which 
increased deferred taxes by $19 million (see Note 3).  The increase in the rate for 2006 was primarily due to the 
absence of an Ohio tax law change that lowered the effective rate in 2005 as well as fewer tax credits from 
synthetic fuel-related investments.  Synthetic fuel tax credits were available through the end of 2007. 

Synthetic fuel 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 2006, the phase-out range was $55.06 to $69.12, 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 66% phase-out of synthetic fuel credits in 2007 based on actual oil prices during the year. 

Net income in 2007 reflects $5 million less in net benefits from these credits, as compared with the same period of 
2006, as shown below:

   Expenses on synthetic fuel related investments

The tax credits generated by NS’ synthetic fuel related investments, which reduced the effective tax rate by 3% in 
2007 and 2006, and 6% in 2005, expired at the end of 2007 and, accordingly, the effective tax rate is expected to 
increase in 2008 (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.   

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES 

Cash provided by operating activities, NS' principal source of liquidity, was $2.3 billion in 2007, compared 
with $2.2 billion in 2006 and $2.1 billion in 2005.  The improvement in 2007 resulted from favorable changes 
in working capital as well as the modest improvement in income from railway operations.  In 2006, higher 
income from railway operations was partially offset by higher income tax payments.  NS had a working capital 
deficit of $273 million at Dec. 31, 2007, compared with working capital of $307 million at Dec. 31, 2006.  The 
change was largely the result of reduced cash and short-term investments that were used to repurchase stock.  
NS expects that cash on hand combined with cash flow provided by operating activities will be sufficient to 
meet its ongoing obligations.  NS’ cash, cash equivalents and short-term investment balances totaled 
$206 million and $918 million at Dec. 31, 2007 and 2006, respectively. 

Contractual obligations at Dec. 31, 2007, comprised of NS' long-term debt (including capital leases) (see Note 7), 
operating leases (see Note 8), agreements with CRC (see Note 4), unconditional purchase obligations (see Note 17), 
long-term advances from Conrail (see Note 4) and unrecognized tax benefits (see Note 3) were as follows:

Cash used for investing activities was $1 billion in 2007, compared with $684 million in 2006 and $1.8 billion in 
2005.  The increase in 2007 primarily reflected lower net proceeds from short-term investment sales and purchases 
and increased property additions.  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. 

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.

For 2008, NS has budgeted $1.43 billion for capital expenditures.  The anticipated spending includes $613 
million for rail, crosstie, ballast and bridge programs, and $339 million is provided for infrastructure and 
expansion investments, including increased mainline capacity, track upgrades and expansions to accommodate 
new customers or traffic and large network public/private partnership investments such as the Heartland 
Corridor and Chicago CREATE programs (see discussion below).  Norfolk Southern expects to spend 
approximately $143 million on intermodal terminals and equipment to add capacity to the intermodal network, 
increased access and capacity for coal and merchandise traffic, and bulk transfer facilities.  Planned equipment 
spending of $264 million provides $119 million for locomotives, including the purchase of 15 new units and 
continued spending on improvements to the locomotive fleet.  Approximately $145 million will be spent on 
freight cars, including the acquisition of 1,330 new higher capacity coal cars as part of a multi-year program to 
replace the existing coal car fleet, the purchase of 321 freight cars upon their lease expiration, 163 multi-level 
automobile racks and improvements to multi-level racks. Norfolk Southern also expects to spend $66 million 
related to computers, systems and information technology.  NS expects to make all of its capital expenditures 
with internally generated funds.

The Meridian Speedway is a 320 mile rail line between Meridian, Mississippi and Shreveport, Louisiana.  On 
May 1, 2006, NS and Kansas City Southern (KCS) formed a joint venture (MSLLC) pursuant to which NS 
expects 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.  To date, NS has 
contributed $240 million.  At the formation of MSLLC, KCS contributed 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 joint venture is expected to increase capacity and improve service 
over the Meridian Speedway into the Southeast. 

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.  During 2006, 
with respect to the tunnel clearance component of the Heartland Corridor, 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 authorized federal funding.  In 2006, NS also 
entered into agreements with two states governing the use of up to $11 million in state funding for the 
Heartland Corridor rail double-stack clearance project.  NS expects to spend about $60 million in connection 
with this project.  NS began work on the Heartland Corridor tunnel clearances in October 2007 and the entire 
project is expected to be completed by 2010. 

The Chicago Region Environmental and Transportation Efficiency (CREATE) project is a public-private 
partnership to reduce rail and highway congestion and add freight and passenger capacity in the metropolitan 
Chicago area.  NS and other railroads have agreed to participate in CREATE.  A portion of the public funding has 
been approved and the parties have developed a list of projects to be included in Phase I of the project.  A total of 
$100 million in public funding has been secured for Phase I and the railroads have contributed an additional 
$100 million.  The railroads expect to complete Phase I over the next three years.  As currently planned, the total 
project is estimated to cost $1.5 billion with city, state and federal support.  If additional public funding is 
secured, the railroads are expected to contribute a total of $232 million towards the entire project with NS’ share 
slated to be $34 million. 

Cash used for financing activities was $1.6 billion in 2007, compared with $1.3 billion in 2006 and $456 million 
in 2005.  The increases reflected higher share repurchases as a part of NS’ ongoing share repurchase program (see 
Note 13), as well as higher debt repayments and increased dividend payments.  Financing activities in 2007 
include $250 million of proceeds from NS’ receivable securitization facility (see Note 7).   

Share repurchases totaled $1.2 billion in 2007 and $964 million in 2006 for the purchase and retirement of 
23.6 million shares and 21.7 million shares, respectively, of common stock as part of NS’ ongoing share repurchase 
program.  In March 2007, NS’ Board of Directors amended NS’ share repurchase program by increasing the 
authorized amount of share repurchases from 50 million to 75 million shares and shortening the authorized period 
from 2015 to 2010.  The timing and volume of purchases is guided by management’s assessment of market 
conditions and other pertinent facts.  To date, almost all of the purchases under the program have been made with 
internally generated cash.  However, future funding sources are expected to include proceeds from the issuance of 
debt, including the use of the receivable securitization program (see Note 7).  Dependent on economic and market 
conditions, NS expects to purchase and retire a similar amount of shares in 2008. 

NS has in place and available a $1 billion, five-year credit agreement expiring in 2012, which provides for 
borrowings at prevailing rates and includes financial covenants.  There were no amounts outstanding under this 
facility at Dec. 31, 2007, and NS is in compliance with all of the financial covenants.  NS also has in place two 
shelf registration statements on Form S-3 filed with the SEC in March 2001 and September 2004 under which up to 
$700 million of additional debt or equity securities could be issued (see Note 7). 

K33 

 
 
 
 
 
 
Looking forward, NS expects to refinance maturing debt over the next several years and modestly increase current 
debt levels.  Overall, NS’ goal is to maintain a capital structure with appropriate leverage to support NS’ business 
strategy and provide flexibility through business cycles. 

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 regularly discusses the development, selection and disclosures 
concerning critical accounting estimates with the Audit Committee of its Board of Directors.  There have been no 
significant changes to the Application of Critical Accounting Estimates disclosure contained in NS’ Form 10-K as 
of Dec. 31, 2007, with the exception of the adoption of Financial Accounting Standards Board Interpretation 
No. 48, “Accounting for Uncertainty in Income Taxes,” which is discussed below in “New Accounting 
Pronouncements” and in Note 3.

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 utilizes an independent consulting 
actuarial firm’s studies 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 $40 million for the year ended Dec. 31, 2007.  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.  In 2007, NS utilized an analysis in which the projected annual cash flows from the 
pension and postretirement benefit plans were matched with a yield curve based on an appropriate universe of high-
quality corporate bonds.  NS used the results of the yield curve to select the discount rate that matches the payment 
stream of the benefits in these plans.  Previously, NS referred to Moody’s seasoned Aa corporate bond yields and 
the changes in such yields in establishing the discount rate.   

NS' net cost for other postretirement benefits, which is also included in “Compensation and benefits,” was 
$76 million for the year ended Dec. 31, 2007.  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, 

K34 

  
 
  
  
 
  
 
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.  In developing these assumptions, NS’ 
management utilizes 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, 2007, amounted to $775 million.  NS' weighted-
average depreciation rates for 2007 are disclosed in Note 5; a one-tenth percentage point increase (or decrease) in 
these rates would have resulted in a $27 million increase (or decrease) to NS' depreciation expense. 

Personal Injury, Environmental and Legal Liabilities 

NS' expense for casualties and other claims, included in “Materials and other,” amounted to $171 million for the 
year ended Dec. 31, 2007.  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. 

To aid in valuing its personal injury liability and determining the amount to accrue during the year, NS’ 
management utilizes studies prepared by an independent consulting actuarial firm.  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 2007, resulted in a decrease 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 ultimate liability could be 
higher or lower. 

K35 

 
  
 
 
 
 
 
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 $16 million in 2007, $19 million in 2006 and 
$16 million in 2005, and capital expenditures totaled approximately $7 million in 2007, $6 million in 2006 and 
$9 million in 2005.  Capital expenditures in 2008 are expected to be comparable to those in 2007. 

NS' Consolidated Balance Sheets included liabilities for environmental exposures in the amount of $46 million at 
Dec. 31, 2007, and $54 million at Dec. 31, 2006 (of which $12 million was accounted for as a current liability at 
Dec. 31, 2007 and 2006).  At Dec. 31, 2007, the liability represented NS' estimate of the probable cleanup and 
remediation costs based on available information at 155 identified locations.  On that date, 13 sites accounted for 
$25 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 32 locations, one or more 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 an assessment of known facts and circumstances, 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. 

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. 

K36 

  
 
 
 
  
  
 
Income Taxes 

NS' net long-term deferred tax liability totaled $6.4 billion at Dec. 31, 2007 (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 
$10 million valuation allowance on $685 million of deferred tax assets as of Dec. 31, 2007, reflecting the 
expectation that most of these assets will be realized.   

In addition, NS has a recorded liability for its estimate of uncertain tax positions taken or expected to be taken 
in a tax return.  Judgment is required in evaluating the application of federal and state tax laws and assessing 
whether it is more likely than not that a tax position will be sustained on examination and, if so, judgment is 
also required as to the measurement of the amount of tax benefit that will realized upon settlement with the 
taxing authority.  Management believes this liability for uncertain tax positions to be adequate.  Income tax 
expense is adjusted in the period in which new information about a tax position becomes available or the final 
outcome differs from the amounts recorded.  For every one half percent change in the 2007 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 labor 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 changes.  The most recent bargaining round began in late 2004.  
Since that time, the railroads have finalized agreements that extend through 2009 with all of the major rail 
unions except the United Transportation Union (UTU) and the International Association of Machinists (IAM).  
A tentative agreement has been reached with the UTU that is subject to ratification by employees. 

NS previously reached separate agreements with the Brotherhood of Locomotive Engineers and Trainmen 
(BLET) and the American Train Dispatchers Association (ATDA) through 2009.  Thus, only the health and 
welfare provisions from the national agreements will apply to NS’ locomotive engineers and ATDA-represented 
dispatchers.  NS recently reached a tentative agreement with BLET that would have further extended its contract 
with that union through 2014.  However, that agreement was not ratified by employees. 

A tentative national agreement with IAM was not ratified by employees.  Negotiations with IAM are being 
mediated by the National Mediation Board (NMB), a federal agency.  The status quo is preserved during 
mediation (that is, the union may not strike and management may not change the labor agreements) while the 
NMB assists the parties in their efforts to reach agreement.   If the NMB 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, 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 time.  

K37 

  
 
 
 
 
  
 
 
 
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.  Locomotive diesel fuel costs represented 14% 
of NS' operating expenses for 2006 and 11% for 2005.   

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, 2007, NS' debt subject to interest rate fluctuations totaled $413 million.  A 1% point increase in 
interest rates would increase NS' total annual interest expense related to all its variable debt by approximately 
$4 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, 2007, the average pay rate under these agreements 
was 5%, and the average receive rate was 7%.  During 2007 and 2006, the effect of the swaps was to reduce interest 
expense by $1 million and $1 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 September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting 
Standards No. 157, Fair Value Measurements.  This statement, effective for interim or annual reporting periods 
beginning after Nov. 15, 2007, establishes a framework for measuring fair value in generally accepted accounting 
principles and expands disclosures about fair value measurements.  NS will adopt the statement in the first quarter 
of 2008 and expects it will not have a material effect on NS’ consolidated financial statements. 

FASB Interpretation No. (FIN) 48, “Accounting for Uncertainty in Income Taxes,” issued in June 2006, 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 adopted this Interpretation in the first quarter of 2007 (see 
Notes 1 and 3). 

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 

K38 

  
  
 
 
 
 
 
 
 
  
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; results of litigation; 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 a discussion of significant risk factors applicable to NS, 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. 

Item 7A.  Quantitative and Qualitative Disclosures about Market Risk. 

The information required by this item is included in Part II, Item 7, “Management's Discussion and Analysis of 
Financial Condition and Results of Operations” under the heading “Market Risks and Hedging Activities.”

Report of Management 

Feb. 15, 2008 

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 Dec. 31, 2007.  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 Dec. 31, 2007. 

KPMG LLP, independent registered public accounting firm, has audited the Corporation's financial statements 
and issued an attestation report on the Corporation's internal control over financial reporting as of Dec. 31, 2007.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders 
Norfolk Southern Corporation: 

We have audited Norfolk Southern Corporation’s internal control over financial reporting as of December 31, 
2007, 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, included in the accompanying Report of Management.  
Our responsibility is to express an opinion on the Company’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, assessing the risk that a material 
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the 
assessed risk.  Our audit also included 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 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 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, Norfolk Southern Corporation maintained, in all material respects, effective internal control over 
financial reporting as of December 31, 2007, based on criteria established in Internal Control – Integrated 
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated balance sheets of Norfolk Southern Corporation as of December 31, 2007 and 
2006, 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, 2007, and our report dated February 15, 2008 expressed 
an unqualified opinion on those consolidated financial statements.

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, 2007 and 2006, 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, 2007. In connection with 
our audits of the consolidated financial statements, we also have audited the financial statement schedule as listed 
in Item 15(A)2. These consolidated financial statements and financial statement schedule are the responsibility of 
the Company’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, 2007 and 2006, and the 
results of their operations and their cash flows for each of the years in the three-year period ended December 31, 
2007, 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 Financial 
Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes, effective 
January 1, 2007, 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), Norfolk Southern Corporation’s internal control over financial reporting as of December 31, 
2007, 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 15, 2008 
expressed an unqualified opinion on the effectiveness of the Company’s 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. 

NSR and its railroad subsidiaries transport raw materials, intermediate products and finished goods classified in 
the following market groups (percent of total railway operating revenues in 2007): coal (25%); intermodal (20%); 
chemicals (13%); metals/construction (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 periodically 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 

K48 

  
 
  
  
  
  
 
 
  
 
  
 
  
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 
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,” 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:

Effective Jan. 1, 2007, NS adopted Financial Accounting Standards Board Interpretation No. 48 (FIN 48), 
“Accounting for Uncertainty in Income Taxes,” which 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 (see Note 3). 

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). 

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 

K49 

  
  
  
  
  
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
 
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. 

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, 2007 and 2006.  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 

K50 

 
  
  
 
 
  
  
  
  
  
  
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 presented in “Railway operating expenses” have been reclassified to conform 
to the current year presentation.  Amounts previously presented as “Diesel fuel” (used in locomotives) have been 
combined with other fuel and related costs and are now presented as “Fuel.”  Additionally, certain other groupings of 
costs within “Railway operating expenses” have been changed.

“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 owned and operated facilities that produced synthetic fuel 
from coal.  In addition, in 2007 NS purchased two facilities that produced synthetic fuel from coal.  The 
production of synthetic fuel resulted in tax credits as well as expenses related to the investments.  The expenses 
are included in “Expenses related to synthetic fuel investments” above. 

“Other current assets” in the Consolidated Balance Sheets includes prepaid interest of $58 million at Dec. 31, 
2007, and $50 million at Dec. 31, 2006, arising from corporate-owned life insurance borrowings.

In August 2007, Illinois enacted tax legislation that modifies the way in which transportation companies 
apportion their taxable income to the state.  The change resulted in an increase in NS’ deferred income tax 
liability in the third quarter, as required by Statement of Financial Accounting Standards No. 109, “Accounting 
for Income Taxes,” which increased deferred tax expense by $19 million. 

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

Except for amounts for which a valuation allowance has been provided, management believes that it is more 
likely than not that the results of future operations will generate sufficient taxable income 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 increased $1 million in 
2007, and decreased $1 million in 2006 and $3 million in 2005. 

Uncertain Tax Positions 

As a result of the implementation of FIN 48 on Jan. 1, 2007 (see Note 1), NS recognized a $10 million increase 
to stockholders’ equity, $2 million of which related to investments accounted for under the equity method of 
accounting.  A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows 
($ in millions): 

Balance at January 1, 2007 

Additions based on tax positions related to the current year 
Additions for tax positions of prior years 
Reductions for tax positions of prior years 
Settlements with taxing authorities 
Lapse of statutes of limitations

Included in the balance of unrecognized tax benefits at December 31, 2007, are potential benefits of 
$56 million that would affect the effective tax rate if recognized.  Unrecognized tax benefits are adjusted in 
the period in which new information about a tax position becomes available or the final outcome differs from 
the amount recorded. 

NS expects that the total amount of unrecognized tax benefits at Dec. 31, 2007, will decrease by between 
$30 million and $35 million in 2008 due to tax positions for which there was an uncertainty about the timing of 
deductibility in earlier years but deductibility may become certain by the close of 2008.  NS’ consolidated 
federal income tax returns for 2004 and 2005 are being audited by the Internal Revenue Service (IRS).  NS 
anticipates that the IRS will complete its examination of the 2004 and 2005 years within the next twelve 
months.  It is reasonably possible that the amount of unrecognized tax benefits will change due to the 
completion of the IRS examination of the 2004 and 2005 years, but an estimate of the change cannot be made.  
The IRS completed its examination of the 2002 and 2003 consolidated federal income tax returns during the 
third quarter of 2006 and NS appealed certain adjustments proposed by the IRS.  State income tax returns 
generally are subject to examination for a period of three to four years after filing of the return.  In addition, NS 
is generally obligated to report changes in taxable income arising from federal income tax examinations to the 
states within a period of up to two years from the date the federal examination is final.  NS has various state 
income tax returns either under examination, administrative appeals, or litigation.  It is reasonably possible that 
the amount of unrecognized tax benefits will decrease in 2008 as a result of the lapse of state statutes of 
limitations, but the amount is not expected to be significant.  NS does not expect that any of the above potential 
changes in unrecognized tax benefits will have a material effect on NS’ financial position, results of operations 
or liquidity. 

Interest related to unrecognized tax benefits, which is included in “Other income – net,” amounted to 
$12 million of expense in 2007 and income of $2 million in 2006 and $12 million in 2005.  Penalties related to 
tax matters are included in “Provision for income taxes” and totaled zero in each of 2007, 2006 and 2005.  NS 
has recorded a liability of $28 million at Dec. 31, 2007, and $17 million at Jan. 1, 2007, for the payment of 
interest on unrecognized tax benefits.  NS has no liability recorded at Dec. 31, 2007, and Jan. 1, 2007, for the 
payment of penalties on unrecognized tax benefits.

Other equity method investments includes $240 million at Dec. 31, 2007, and $100 million at Dec. 31, 2006, 
related to NS’ investment in Meridian Speedway LLC, a joint venture formed with Kansas City Southern in 2006. 

Investment in Conrail 

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.  NS is applying 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 useful lives of Conrail’s depreciable property and equipment, 
including the related deferred tax effect of the differences in tax accounting bases for such assets, as all of the 
purchase price at acquisition was allocable to Conrail’s tangible assets and liabilities.  At Dec. 31, 2007, the 
difference between NS’ investment in Conrail and its share of Conrail’s underlying net equity was 
$555 million. 

CRC owns and operates certain properties (the Shared Assets Areas) for the joint and exclusive 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.  "Purchased 
services and rents" includes expenses for amounts due to CRC for operation of the Shared Assets Areas of $126 
million in 2007 and 2006, and $129 million in 2005.  Future minimum lease payments due to CRC under the Shared 
Assets Areas agreements are as follows: $28 million in each of 2008 through 2012 and $317 million thereafter.  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. 

“Accounts payable” includes $78 million at Dec. 31, 2007, and $68 million at Dec. 31, 2006, due to Conrail for 
the operation of the Shared Assets Areas.  In addition, “Other liabilities” includes $133 million at Dec. 31, 2007 
and 2006 for long-term advances from Conrail, maturing 2035, entered into in 2005 that bear interest at an 
average rate of 4.4%.

In November 2007, NS entered into a $500 million receivables securitization facility under which NSR sells 
substantially all of its eligible third-party receivables to an NS subsidiary, which in turn may transfer beneficial 
interests in the receivables to various commercial paper vehicles.  Amounts received under the facility are 
accounted for as borrowings.  The facility has a 364-day term; however, NS intends to refinance these borrowings 
by issuing long-term debt, which is supported by its $1 billion credit agreement (see below).  Accordingly, 
amounts outstanding are included in the line item “Long-term debt” in the Consolidated Balance Sheet.  At 
Dec. 31, 2007, the amount of receivables included in “Accounts receivable – net” serving as collateral for these 
borrowings was $778 million. 

In May 2005, NS issued $717 million of unsecured notes ($350 million at 5.64% due 2029 and $367 million at 
5.59% due 2025) and paid $218 million of premium in exchange for $717 million of its 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).  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. 

“Discounts and premiums, net” at Dec. 31, 2007 and 2006, includes $126 million and $130 million, 
respectively, related to $314 million face amount of 9.75% notes due in 2020 and $138 million face amount 
of 7.875% notes due 2043, which is being amortized as a reduction of interest expense over the terms of the 
notes, resulting in effective interest rates of 6.0% and 6.2%, respectively.

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 $80 million at Dec. 31, 2007, and $85 million at Dec. 31, 2006. 

Shelf Registration  

NS has on file with the Securities and Exchange Commission two Form S-3 shelf registration statements, under 
which up to $700 million of additional debt or equity securities could be issued.   

Credit Agreement, Debt Covenants and Commercial Paper 

NS has in place a five-year $1 billion credit facility expiring in 2012.  Any borrowings under the credit agreement 
are contingent on the continuing effectiveness of certain 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 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, 2007, 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, 2007, and 
Dec. 31, 2006, 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, co-payments, 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.  In addition, NS recognized a $2 million 
reduction to stockholders’ equity related to its proportionate share of Conrail’s adoption of SFAS 158.  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.

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 $159 million at Dec. 31, 2007, and 
$152 million at Dec. 31, 2006, and had accumulated benefit obligations of $137 million at Dec. 31, 2007, and 
$125 million at Dec. 31, 2006.

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 $7 million and 
$3 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 $30 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

To determine the discount rate in 2007, NS utilized an analysis in which the projected annual cash flows from the 
pension and postretirement benefit plans were matched with a yield curve based on an appropriate universe of 
high-quality corporate bonds.  NS used the results of the yield curve to select the discount rate that matches the 
payment stream of the benefits in these plans.  Previously, NS referred to Moody’s seasoned Aa corporate bond 
yields and the changes in such yields in establishing the discount rate. 

Health Care Cost Trend Assumptions 

For measurement purposes at Dec. 31, 2007, increases in the per capita cost of covered health care benefits were 
assumed to be 9% for 2007 and 8.5% for 2008.  It is assumed the rate will decrease gradually to an ultimate rate 
of 5% for 2012 and remain at that level thereafter. 

Assumed health care cost trend rates have a significant effect on the amounts reported in the financial 
statements.  To illustrate, a one-percentage-point change in the assumed health care cost trend would have the 
following effects:

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, 2007 and 2006, 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, 2007, of 65% in equity securities and 35% in debt securities compared with 67% in 
equity securities and 33% in debt securities at Dec. 31, 2006.  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 2008, NS expects to contribute approximately $9 million to its unfunded pension plans for payments to 
pensioners and $48 million to its other postretirement benefit plans for retiree health benefits. 

Benefit payments, which reflect expected future service, as appropriate, are expected to be paid as follows:

The other postretirement benefit payments include an estimated annual reduction due to the Medicare Part D 
Subsidy of about $6 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 $27 million in 2007 and $26 million in 2006 
and 2005.

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 2007 and 2006, and $13 million in 2005. 

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; as a broad-based stock option plan, stockholder approval of TSOP was not required.  NS uses 
newly issued shares to satisfy any exercises and awards under LTIP and TSOP. 

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 2007, a committee of nonemployee directors of NS’ Board granted stock options, 
restricted stock units and PSUs pursuant to the LTIP and granted stock options pursuant to the TSOP.  
Receipt of an award under LTIP was made contingent upon the awardee’s execution of a non-compete 
agreement, and all awards under LTIP were made subject to forfeiture in the event the awardee “engages in 
competing employment” for a period of time following retirement. 

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 $96 million in 2007, $129 million in 2006 and $75 million in 2005.  The total tax effect recognized 
in income in relation to stock-based compensation was a benefit of $32 million in 2007, $44 million in 2006 and 
$27 million in 2005. 

Stock Options 

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.  In the first quarter of 2007, 1,203,300 options were granted under the LTIP and 251,000 options were 
granted under the TSOP.  In each case, the grant price was $49.555, 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 third 

K64 

 
 
  
 
 
 
  
 
 
anniversary of the date of grant.  Holders of the options granted under LTIP who remain employed by NS receive 
cash dividend equivalent payments for five years commensurate with dividends paid on Common Stock. 

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. 

The fair value of each option award in 2007 and 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 was determined using the Black-Scholes option-pricing model.  The assumptions for 2007, 2006 and 
2005 are shown in the following table:

The grant date fair value of the 2007 TSOP grant was $17.88 using the same assumptions as the 2007 LTIP grant, 
except a dividend yield of 1.5% was used because no dividend equivalents are paid on these options and the 
average expected option term was 6.5 years.

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 Statements 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 Statements of 
Cash Flows for the years ended Dec. 31, 2007 and 2006, included $57 million and $85 million of such tax 
benefits, respectively. 

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 zero and 321,450, respectively, in 2007, with a grant-date 
fair value of $50.01 and a 5-year restriction period, and 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.  Restricted stock units granted in 
2007 will be settled through issuance of shares of Common Stock.  The restricted stock unit grants include cash 
dividend equivalent payments during the restriction period commensurate with dividends paid on Common Stock. 

A summary of the status of restricted shares and restricted stock units as of Dec. 31, 2007, and changes during the 
twelve months then ended is presented below:

At Dec. 31, 2007, there was $16 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 
2.1 years.  The total fair value of the restricted shares vested and restricted stock units paid in cash during the 
twelve months ended Dec. 31, 2007, 2006 and 2005 was $22 million, $40 million and $2 million, respectively.  
The total related tax benefit realized was $3 million in 2007 and $6 million in 2006. 

Performance Share Units 

PSUs provide for awards based on achievement of certain predetermined corporate performance goals (total

13.  Stock Purchase Program 

In March 2007, NS’ Board of Directors amended NS’ share repurchase program and increased the authorized 
amount of share repurchases from 50 million to 75 million shares and shortened the authorized period from 2015 
to 2010.  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 23.6 million shares and 21.7 million shares of its common 
stock under this program in 2007 and 2006, respectively, at a cost of $1.2 billion and $964 million, respectively.

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 and investments accounted for under the equity 
method in accordance with APB Opinion No. 18, consisted of the following at Dec. 31:

Underlying net assets were used to estimate the fair value of 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 zero on Dec. 31, 2007, and $1 
million on Dec. 31, 2006.  Sales of “available-for-sale” securities were immaterial for the years ended Dec. 31, 
2007, 2006 and 2005; 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. 

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 

From 2001 until May 2004, NS entered into contracts that hedged 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.  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% and 11% of NS’ operating expenses for the 
years ended Dec. 31, 2006 and 2005, respectively.  The last remaining contracts were settled in the second quarter 
of 2006, bringing an end to this program.  NS' fuel hedging activity resulted in decreases in diesel fuel expenses 

K71 

  
  
 
 
 
 
 
 
 
 
  
  
 
 
 
  
  
  
  
of $20 million in 2006 and $148 million in 2005.  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 and a $5 million expense in 2005. 

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 $59 million and $83 million, or about 1%, of its fixed rate debt portfolio hedged as of Dec. 31, 
2007, and Dec. 31, 2006, 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 for 
2007 and 2006, and $2 million for 2005.  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 

Fair values of interest rate swaps at Dec. 31, 2007, and Dec. 31, 2006, 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.  The total net asset position of NS’ outstanding derivative financial instruments was comprised of 
a gross fair value asset position of $1 million at both Dec. 31, 2007, and Dec. 31, 2006. 

 17.  Commitments and Contingencies 

Lawsuits 

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. 

Casualty Claims 

Casualty claims include employee personal injury and occupational claims as well as third-party claims, all 
exclusive of legal costs.  To aid in valuing its personal injury liability and determining the amount to accrue 
during the year, NS’ management utilizes studies prepared by an independent consulting actuarial firm.  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. 

K72 

 
  
 
  
 
 
  
 
 
 
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.  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.  Expenses in 2005 included $41 million related to this incident, 
representing NS’ retention under its insurance policies and other uninsured costs. 

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 quarterly based 
upon management’s assessment and the results of the study.  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 amount recorded. 

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 quarterly based upon management’s assessment and the results of the study.  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 based upon management’s 
assessment and the results of the study.  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 

K73 

 
 
 
 
  
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 $46 million at 
Dec. 31, 2007, and $54 million at Dec. 31, 2006 (of which $12 million was accounted for as a current liability at 
Dec. 31, 2007 and 2006).  At Dec. 31, 2007, the liability represented NS' estimate of the probable cleanup and 
remediation costs based on available information at 155 known locations compared with 172 locations at Dec. 31, 
2006.  On that date, 13 sites accounted for $25 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 32 locations, one or more 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. 

Insurance 

NS obtains on behalf of itself and its subsidiaries insurance for potential losses for third-party liability and first-
party property damages.  NS is currently self-insured up to $25 million and above $1 billion per occurrence for 
bodily injury and property damage to third parties and up to $25 million and above $175 million per occurrence 
for property owned by NS or in NS’ care, custody or control. 

K74 

  
 
 
  
 
 
 
 
Purchase Commitments 

At Dec. 31, 2007, NSR had outstanding purchase commitments of approximately $298 million primarily for 
coal hoppers, locomotives, RoadRailer® trailers, and track material in connection with its capital programs 
through 2009. 

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 Norfolk Southern, 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, 2007, 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.

Item 9.  Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. 

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, 2007.  
Based on such evaluation, such officers have concluded that, as of Dec. 31, 2007, 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 the 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.  Norfolk Southern’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 Norfolk Southern’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, 2007.  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 Norfolk Southern maintained effective internal control 
over financial reporting as of Dec. 31, 2007. 

The Board of Directors, acting through its Audit Committee, is responsible for the oversight of Norfolk Southern'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 an attestation report on Norfolk 
Southern’s internal controls over financial reporting as of Dec. 31, 2007.  These reports appear in Part II, Item 8 
of this report on Form 10-K. 

During the fourth quarter of 2007, management has not identified any changes in internal controls over financial 
reporting that have materially affected, or are reasonably likely to materially affect, NS’ internal control over 
financial reporting.

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 8,500,000 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 make awards under LTIP subject to forfeiture under certain circumstances and may 
establish such other 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 2007 
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 as compared with the average total return on all 
stocks comprising the S&P 500 composite stock price index.  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).  
The Committee at its discretion may waive the restriction period. 

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.  
There are 6,000,000 shares of authorized but unissued Common Stock 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 Committee 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.  Options awarded in 2007 are subject to a three-year vesting period.  
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 Norfolk Southern 
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.
