The GMD SW1200MG is a four-axle electric locomotive built by General Motors Diesel between 1963 and 1971. It is the electric counterpart of the diesel-powered SW1200, with the prime mover replaced by a motor-generator set, which accounts for the MG suffix in the model number. The locomotives run on a 2400 volt, 60 hertz supply and operate under automatic control without a driver. The difference from the diesel SW1200 is that a single-phase electric motor is fitted in place of the diesel engine, with adapted controls. Nine examples were built, all for a single Canadian customer, the Iron Ore Company of Canada.
