CSX Transportation (reporting mark CSXT), known colloquially as simply CSX, is a Class I freight railroad company operating in the Eastern United States and the Canadian provinces of Ontario and Quebec. Operating about 21,000 route miles (34,000 km) of track,^[1] it is the leading subsidiary of CSX Corporation, a Fortune 500 company headquartered in Jacksonville, Florida.^[2][3]

CSX Corporation was formed in 1980 from the merger of Chessie System and Seaboard Coast Line Industries, two holding companies that controlled railroads operating in the Eastern United States. Initially only a holding company, the subsidiaries that made up CSX Corporation completed merging in 1987. CSX Transportation formally came into existence in 1986, as the successor of Seaboard System Railroad. In 1999, CSX Transportation acquired about half of Conrail in a joint purchase with competitor Norfolk Southern Railway. In 2022, it acquired Pan Am Railways, extending its reach into northern New England.

Norfolk Southern remains CSX's chief competitor; the two share a duopoly on transcontinental freight rail lines in the east half of the US.
