Beginning In 1972, American railroad companies Seaboard Coast Line and the Louisville & Nashville Railroad began jointly marketing themselves as the Family Lines System. This also extended to their subsidiary companies the Georgia Railroad, the Atlanta and West Point Railroad, the Clinchfield Railroad, and the Western Railway of Alabama. The use of this marketing device persisted until 1983, when a merger between Seaboard Coast Line and the Louisville and Nashville resulted in the Seaboard System Railroad, which in 1986 merged with the Chessie System to become CSX Transportation.
