History
From Columbia north to Camden, the line was built by the Florida Central and Peninsular Railroad as an extension of the South Bound Railroad in the late 1890s.

From Camden to Cheraw, the line was built by the Chesterfield and Kershaw Railroad, which was chartered by the South Carolina General Assembly in 1899.

From Cheraw to Hamlet, the line was built by the Palmetto Railroad, which was completed in 1887.

The Florida Central and Peninsular Railroad, the Chesterfield and Kershaw Railroad, and the Palmetto Railroad all became part of the Seaboard Air Line Railroad in 1900. The unified line became a segment of the Seaboard main line. The Seaboard Air Line designated this segment of the main line as the Hamlet Subdivision, which it is still known as today. Seaboard would eventually become CSX by the 1980s.
