CSX Transportation (CSXT) is a Class I freight railroad operating 21,000 route miles across eastern North America, and the principal subsidiary of the CSX Corporation. The company founded in 1980 by the merger of the Cleveland, Ohio-based Chessie System with Seaboard Coast Line Industries of Jacksonville, Florida, which operated the Seaboard Coast Line and Louisville & Nashville Railroads. The combination was enabled under the terms of the Staggers Rail Act of 1980.
The company's lines continued to operate under separate names until 1986–1987. CSX and Norfolk Southern Railway jointly acquired the Conrail system in 1998, dividing the assets between them. CSX took over operation of much of the former New York Central Railroad, extending into Canada. Beginning in 2017 under the leadership of then-CEO E. Hunter Harrison the carrier has transitioned toward "precision railroading," reducing its workforce and rolling stock. For liability reasons, CSX Transportation bars steam-powered and other antique locomotives from operating on its trackage.
