Jacksonville, Fla.-based CSX Transportation operates the largest rail network in the eastern United States and CSX Intermodal provides transportation services across the United States and into key markets in Canada and Mexico.

CSX Corporation subsidiaries also perform maritime operations, including an international terminal services company. The railroad operates a network in 23 states, the District of Columbia and two Canadian provinces.

CSX Transportation was formed on July 1, 1986, basically as a renaming of the Seaboard System Railroad, which previously absorbed the Atlantic Coast Line Railroad, Louisville and Nashville Railroad, the Seaboard Air Line Railroad and several smaller lines.

On Aug. 31, 1987, the Chesapeake and Ohio Railway, which had absorbed the Baltimore and Ohio Railroad April 30, 1987, merged into CSX. That merger started in 1980 with the combining of the Chessie System and Seaboard Coast Line Industries into CSX Corp.

CSX’s name dates back to merger talks between the Chessie System and the Seaboard System Railroad, both known as Chessie and Seaboard. Chairmen for the two companies wanted the initial to be included in the new company’s name; similar names CSC and CSM were already taken.

In the end, the company went with CSX, which is supposed to stand for Chessie Seaboard X (multiplied).
