The Seaboard System Railroad was a railroad subsidiary of the CSX Corporation, created as an intermediate step in the mergers that would form CSX Transportation. Its roots were in the Family Lines System, a marketing name adopted by the Seaboard Coast Line Railroad (SCL, a 1967 consolidation of the Atlantic Coast Line and Seaboard Air Line Railroads) and its subsidiaries in 1972. Under this relationship, equipment of the SCL, Louisville and Nashville Railroad (L&N), Georgia Railroad, Clinchfield Railroad, and West Point Route (Atlanta and West Point Railroad and Western Railway of Alabama) was repainted gray with yellow and red stripes, but the six companies continued to operate separately.
