South Georgia 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 7 (Locobase 12284)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 21, p. 216. See also Donald R. Hensley, Jr., "The South Georgia Railway", archived at TapLines http://www.taplines.net/southgeorgia/sgry1.htm . Works number was 15987 in June 1898.

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.
