The SG originally ran from Heartpine, Ga to Quitman, then to Greenville, Fla, 50 miles away from its origin. It was later known as the South Georgia & West Coast, although its incorporation papers were never formally changed. By 1904, the West Coast leg had been extended to Perry, Fla, 76 miles away.
The 7 was lettered for the South Georgia. In 1906, the 7 was sold to the Kirby Planing Mill. It later operated on the Lakeland Railroad.
