In 1967, ACL merged with the Seaboard Air Line Railroad to form the Seaboard Coast Line Railroad (SCL). SCL continued to operate the Georgia Railroad as a subsidiary alongside the Louisville & Nashville Railroad and the Clinchfield Railroad. These were known collectively as the "Family Lines System." SCL continued to operate the Georgia Railroad under its initial charter; the Georgia Railroad was maintained as a separate company, with SCL leasing the rail properties. Two years later, the Georgia Railroad ended its traditional passenger service, though it continued to operate a bare-bones mixed train service between Atlanta (Atlanta Union Station) and Augusta (Augusta Union Station).
