 The line, the Tallahassee Railroad, was constructed about 1836, and until the Civil War it served in the export of Middle Florida's cotton through St. Marks.The capacity of the St. Marks port was limited, and it was surpassed in the 19th century by the larger port of Apalachicola, served by the Thomasville, Tallahassee and Gulf Railroad via Carrabelle, Florida.Today the attraction of St. Marks for boaters, fishermen, and seafood lovers preserves a strong relationship with Tallahassee (as does the location of a generating plant for Tallahassee here).
