The EMD G12 is a class of export locomotive built by GM-EMD, and its Canadian affiliate General Motors Diesel. In addition, Australian licensee Clyde Engineering built ten locomotives for New Zealand in 1957, five for Hong Kong, 23 for Queensland, fourteen for Western Australia and seven for BHP. Australian licensee Commonwealth Engineering also built 42 for Queensland Rail in 1964–1966. Many examples were built in the 1950-1960s for railroads around the world. They are powered by EMD 12-567C prime movers rated at 1250 hp; some have been rebuilt with EMD 645 engines. The A1A-A1A and C-C versions had a lower axle loading than the B-B version.

Preservation

KORAIL 4102 is the only preserved G12 in Korea, plinthed in front of Daejeon MPD, alongside a single SD9 5025. Both engines worked for the construction of KTX's Gyeongbu section as departmental vehicles upon the retirement of KORAIL. A former Australian-built KCRC G12 is preserved in the Hong Kong Railway Museum.
