On November 1, 1980, CSX Corporation was created as a holding company for the Family Lines and Chessie System Railroad. Effective January 1, 1983, the Seaboard Coast Line Railroad became Seaboard System Railroad after a merger with the Louisville and Nashville Railroad and Clinchfield Railroad. For some years prior to this, the SCL and L&N had been under the common ownership of a holding company, Seaboard Coast Line Industries (SCLI), the company's railroad subsidiaries being collectively known as the Family Lines System which consisted of the L&N, SCL, Clinchfield and West Point Routes. During this time, the railroads adopted the same paint schemes but continued to operate as separate railroads.
