The Cheraw and Darlington Railroad completed their line between Florence and Cheraw in 1853, passing through the towns of Society Hill and Floyds. In 1898, the C&D merged into the Atlantic Coast Line Railroad, and this line became part of that railroad's purview.
The merger between the Atlantic Coast Line and Seaboard Air Line in 1967 to form the Seaboard Coast Line provided more practical access to Society Hill via the former SAL S Line, rendering the section between Floyd and Cheraw an unnecessary line. Topographic maps show that this section crossed a number of creeks and small rivers, and much swampland, and was probably expensive to maintain and use. The section between Floyd and Society Hill was abandoned in the very early 1980s by Seaboard System or CSX; the rest of the line to Cheraw was abandoned February 8, 2012 by the South Carolina Central Railroad.
