CSX Transportation: A Powerhouse of Eastern North American Rail
CSX Transportation (reporting mark CSXT), commonly known as CSX, is a premier Class I freight railroad that serves as a critical artery for commerce across the Eastern United States and the Canadian provinces of Ontario and Quebec. As the primary subsidiary of the Fortune 500 CSX Corporation, the company manages an expansive network of approximately 21,000 route miles (34,000 km) of track.
Headquartered in Jacksonville, Florida, CSX operates as a cornerstone of North American logistics, moving vast quantities of freight through the Northeastern, Southern, and Midwestern regions. Its evolution from a collection of historic regional lines into a modern transportation giant is a story of strategic consolidation and industrial growth.

The Evolution of CSX: From Mergers to Modernity
Foundations and Early Consolidation
The roots of CSX stretch back to the 1820s with the formation of the Baltimore and Ohio Railroad (B&O). Throughout the mid-20th century, the industry saw a wave of consolidation. A pivotal shift occurred in December 1962 when the Chesapeake and Ohio Railway (C&O) took control of the B&O. By 1980, the CSX Corporation was formed as a holding company through the merger of the Chessie System and Seaboard Coast Line Industries.
For several years, CSX existed primarily as a "paper railroad," meaning it did not yet have its own branded locomotives. This changed in 1986 when the Seaboard System was renamed CSX Transportation. By August 31, 1987, the final merger of the C&O and Chessie System into CSX Transportation brought all major subsidiaries under a single operational banner.
Strategic Acquisitions
CSX continued to expand its footprint through high-profile acquisitions. In 1999, in a joint venture with competitor Norfolk Southern Railway, CSX acquired roughly half of Conrail. More recently, CSX extended its reach into northern New England by completing the purchase of Pan Am Railways on June 1, 2022.
In late 2024, the company further refined its network. On November 16, 2024, an agreement became effective allowing CSX to resume operations on 93.7 miles of track leased from the Meridian and Bigbee Railroad (M&B) between Burkville and Myrtlewood.
Operational Highlights and Specialized Services
Unit Trains and Logistics
CSX is known for operating unit trains—trains where all cars carry the same commodity from a single origin to a single destination. A notable example was the "Juice Train," which transported Tropicana orange juice from Bradenton, Florida, to Jersey City, New Jersey. While the long-haul dedicated service north of Tampa was abolished in 2017 in favor of mixed freight, the service continues as a local operation (O823) between Bradenton and Tampa.
Locomotive Fleet and Modernization
The CSX fleet is undergoing significant modernization. The company has partnered with Wabtec to upgrade its CW44 locomotives, with a massive agreement reached in February 2024 to modernize over 200 units through 2028. These modernized units are classified as CM44AC.
CSX also maintains a tradition of commemorative and heritage locomotives. In May 2023, the company launched a heritage unit program, painting locomotives to honor predecessor railroads, such as the Baltimore and Ohio. Other special units have been unveiled to honor first responders, veterans, and the "One CSX" employee initiative.
Infrastructure and Safety
Major Hubs
To manage its vast traffic, CSX utilizes several hump yards—classification yards that use a gravity-based hill (hump) to sort railcars. Key facilities include:
- Selkirk Yard (Selkirk, New York)
- Rice Yard (Waycross, Georgia)
- Queensgate Yard (Cincinnati, Ohio)
- Avon Yard (Avon, Indiana)
- Radnor Yard (Nashville, Tennessee)
Safety Record
Like all major rail operators, CSX has faced significant challenges. Notable incidents include the 2001 CSX 8888 incident in Ohio (which inspired the film Unstoppable), the 2018 Cayce, South Carolina collision involving an Amtrak train, and various derailments caused by environmental factors, such as the EF4 tornado in Barnsley, Kentucky, in 2021.
