Central of Georgia class ML
United States 1919 10 produced
In 1919, the Central of Georgia got ten 2-6-6-2 Mallets from ALCO-Richmond which were used as pushers on the Sylacauga grade in Alabama. They had 57-inch drivers and cylinders with diameters of 24 and 38 inches, with a stroke of 32 inches. Apparently, they were not very popular among the footplate and maintenance crews and had steam leaks in many places. As it turned out that these locomotives were too large for the small railroad, they were given to the Illinois Central that was a shareholder of the Central of Georgia in 1926. In exchange, they received some 2-10-2 locomotives. The Mallets got the numbers 6000 to 6009 from the IC and were used as switchers for about ten years.
