The C&O bought two 4-8-2s from the American Locomotive Company and designated them Class J-1. They were assigned road numbers 316 and 317 and were put to test in June, 1911. Another one, road number 318, was ordered and delivered from ALCO in 1912. All three worked well in passenger service.
In 1918, three "Mountains" (road numbers 133 through 135) with 69" drivers were received from ALCO and two (road numbers 136 and 137) came from the Baldwin Locomotive Works. These five locomotives were built according to USRA specifications and were of the Heavy Mountain design and were designated Class J-2 by the C&O.
In June of 1923, a final two of the Class J-2 locomotives (road numbers 138 and 139) were delivered by ALCO. By 1924, all ten of the C&O "Mountains" were renumbered 540 through 549.
The C&O had a locomotive modernization program in the 1930s and the seven Class J-2 "Mountains received new cabs, new feedwater heaters, the flying-pump front ends, a general overhaul and Vanderbilt tenders.
All ten of the "Mountains" were retired and scrapped by 1952.
