Central of Georgia 2-6-6-2 Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class ML (Locobase 7111)

Data from the CofGA 11 - 1925 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Raildata collection. Works numbers were 59038-59047

These light Mallets served as pushers on the Sylacauga grade in Alabama, but proved to be overpowered for the Central. They were traded to the Illinois Central in 1926 for some Santa Fes. That railroad, which had gained control of the C of Ga in 1907, operated them as 6000-6009 for about 10 years before scrapping them.
