Middle Georgia & Atlantic / Central of Georgia 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 8 / T (Locobase 7902)

Data from the CofGA 1905 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works number was 14993.

This engine differs from the 1356 class shown in Locobase 7901 in having the firebox ride above the rear two axles rather than between them. The MG & A was taken into the C of G in 1897 and the 8 went with the rest. Renumbered 3 times, 231 (ex-1321, ex-1365) was finally retired in May 1939.
