Dates of Operation: 1900-1967 (67 years)
The Atlantic Coast Line serviced most of the Southeast, much like its biggest competitor, Louisville & Nashville. Unfortunately because of this, ACL was not the most successful railroad. Although having one of the most beautiful and unique paint schemes, competition grew. In early October of 1958, another class I railroad was on the rise. Its other fierce competitor, Seaboard Air Line, had begun to discuss a possible merger. In 1967, the merger of the Atlantic Coast Line and Seaboard Air Line became official, thus creating the Seaboard Coast Line.
However, both railroads continued their rivalry with the Louisville & Nashville even after the name was changed to Seaboard Coast Line. The two had a long feud, but in the end, it was SCL that took over the remaining operations. The still prosperous L&N "Old Reliable" would be known as an equal, making the new railroad, "SCL/L&N" in 1971. However, multiple railroads had entered into the picture. Notable ones included the Clinchfield (CRR), Atlanta & West Point (A&WP), and the Georgia Railroad (GA). This became known as the "Family Lines System". Family Lines System changed their name to "Seaboard System" (SBD) in later years.
