Item 2. Properties

The Company’s properties primarily consist of track and its related infrastructure, locomotives and freight cars and equipment. These categories and the geography of the network are described below.

Track and Infrastructure

Serving 23 states, the District of Columbia, and the Canadian provinces of Ontario and Quebec, the CSXT rail network serves, among other markets, New York, Philadelphia and Boston in the Northeast and Mid-Atlantic, the southeast markets of Atlanta, Miami and New Orleans, and the midwestern cities of St. Louis, Memphis and Chicago.

CSXT’s track structure includes main thoroughfares, connecting terminals and yards (known as mainline track), track within terminals and switching yards, track adjacent to the mainlines used for passing trains, track connecting the mainline track to customer locations and track that diverts trains from one track to another known as turnouts. Total track miles are greater than CSXT’s approximately 21,000 route miles, which reflect the size of CSXT’s network that connects markets, customers and western railroads. At December 2015, the breakdown of track miles was as follows:

In addition to its physical track structure, CSXT operates numerous yards and terminals. These serve as hubs between CSXT and its local customers and as sorting facilities where railcars often are received, re-sorted and placed onto new outbound trains. The Company’s ten largest yards and terminals based on annual volume (number of railcars or intermodal containers processed) are listed in the table below.

Network Geography

CSXT’s operations are primarily focused on four major transportation networks and corridors which are defined geographically and by commodity flows below.

Interstate 90 (I-90) Corridor – This CSXT corridor links Chicago and the Midwest to metropolitan areas in New York and New England. This route, also known as the “waterlevel route,” has minimal hills and grades and nearly all of it has two main tracks (referred to as double track). These superior engineering attributes permit the corridor to support consistent, high-speed intermodal, automotive and merchandise service. This corridor is a primary route for import traffic coming from the far east through western ports moving eastward across the country, through Chicago and into the population centers in the Northeast. The I-90 Corridor is also a critical link between ports in New York, New Jersey, and Pennsylvania and consumption markets in the Midwest. This route carries consumer goods from all three of the Company’s major markets – merchandise, coal and intermodal.

Interstate 95 (I-95) Corridor – The CSXT I-95 Corridor connects Charleston, Jacksonville, Miami and many other cities throughout the Southeast with the heavily populated mid-Atlantic and northeastern cities of Baltimore, Philadelphia and New York. CSXT primarily transports food and consumer products, as well as metals and chemicals along this line. It is the only rail corridor along the eastern seaboard south of the District of Columbia, and provides access to major eastern ports.

Southeastern Corridor – This critical part of the network runs between CSXT’s western gateways of Chicago, St. Louis and Memphis through the cities of Nashville, Birmingham, and Atlanta and markets in the Southeast. The Southeastern Corridor is the premier rail route connecting these key cities, gateways, and markets and positions CSXT to efficiently handle projected traffic volumes of intermodal, automotive and general merchandise traffic. The corridor also provides direct rail service between the coal reserves of the southern Illinois basin and the demand for coal in the Southeast.

Coal Network – The CSXT coal network connects the coal mining operations in the Appalachian mountain region and Illinois basin with industrial areas in the Southeast, Northeast and Mid-Atlantic, as well as many river, lake, and deep water port facilities. CSXT’s coal network is well positioned to supply utility markets in both the Northeast and Southeast and to transport coal shipments for export outside of the U.S. Roughly one-third of the tons of export coal and the majority of the domestic coal that the Company transports is used for generating electricity.

Locomotives

CSXT owns and long-term leases nearly 4,500 locomotives, almost all of which are owned by CSXT. From time to time, the Company also short-term leases locomotives based on business needs. Freight locomotives are the power source used primarily to pull trains. Switching locomotives are used in yards to sort railcars so that the right railcar is attached to the right train in order to deliver it to its final destination. Auxiliary units are typically used to provide extra traction for heavy trains in hilly terrain. At December 2015, CSXT’s fleet of owned and long-term leased locomotives consisted of the following types of locomotives:

Equipment

In 2015, the average daily fleet of cars on line consisted of approximately 206,000 cars. At any time, over half of the railcars on the CSXT system are not owned or leased by the Company. Examples of these non-CSXT railcars are as follows: railcars owned by other railroads (which are utilized by CSXT), shipper-furnished or private cars (which are generally used only in that shipper’s service) and multi-level railcars used to transport automobiles (which are shared among railroads).

The Company’s revenue generating equipment (either owned or long-term leased) consists of freight cars and containers as described below.

Gondolas – Support CSXT’s metals markets and provide transport for woodchips and other bulk commodities. Some gondolas are equipped with special hoods for protecting products like coil and sheet steel.

Open-top hoppers – Transport heavy dry bulk commodities such as coal, coke, stone, sand, ores and gravel that are resistant to weather conditions.

Box cars – Include a variety of tonnages, sizes, door configurations and heights to accommodate a wide range of finished products, including paper, auto parts, appliances and building materials. Insulated box cars deliver food products, canned goods, beer and wine.

Covered hoppers – Have a permanent roof and are segregated based upon commodity density. Lighter bulk commodities such as grain, fertilizer, flour, salt, sugar, clay and lime are shipped in large cars called jumbo covered hoppers. Heavier commodities like cement, ground limestone and sand are shipped in small cube covered hoppers.

Multi-level flat cars – Transport finished automobiles and are differentiated by the number of levels: bi-levels for large vehicles such as pickup trucks and SUVs and tri-levels for sedans and smaller automobiles.

Flat cars – Used for shipping intermodal containers and trailers or bulk and finished goods, such as lumber, pipe, plywood, drywall and pulpwood.

Containers – Weather-proof boxes used for bulk shipment of freight.

Other cars on the network consist primarily of refrigerated boxcars for transporting perishable items.
