. Known as the Family Lines System from 1972-1982, to better compete with the Southern Railway System. this entity adopted its own logo and colors, but each railroad maintained its own identity. Over time, this caused confusion among customers. In comparison to the neighboring

, which had four railroads, the Family Lines had six railroads. In 1971 SCL bought out the remaining shares and made the Louisville & Nashville a subsidiary. On November 1, 1980, Seaboard Coast Lines Industries and Chessie System merged under the holding company

. Over the following seven years, the Chessie and Seaboard's various railroads were gradually merged into one. The first step came on December 29, 1982, when the

and
