Columbia Subdivision

The Columbia Subdivision was originally built by the South Bound Railroad which opened in 1891. Two years later, the South Bound Railroad was leased by the Florida Central and Peninsular Railroad, which operated a vast railroad network in Florida and southern Georgia.^[3]

After leasing the South Bound Railroad, the FC&P would extend its Northern Division to Savannah to connect with the South Bound Railroad and making a continuous route from Columbia to Jacksonville. This extension opened in 1894. The line would be extended north to Camden, South Carolina by the end of the decade (this extension is now part of the Hamlet Subdivision).^[4]

The line would become part of the main line of the Seaboard Air Line Railroad in 1900, after they bought the Florida Central and Peninsular Railroad. The Seaboard Air Line designated the line as the Columbia Subdivision, which it is still known as today.^[5] Through various mergers, the company became CSX Transportation by 1986. The line continues to be part of CSX's S Line (the designation given to the former Seaboard main line).
