The EMD SW1200MG was a 4-axle electric locomotive built by General Motors Diesel between 1963 and 1971. This locomotive was the electric version of the diesel powered SW1200, with the prime mover replaced by a motor-generator set, hence the MG suffix in the model number.

Locomotives run under 2400V 60 Hz, in automatic control without driver.[clarification needed] The difference with SW1200 is that a single-phase electric motor is provided in place of the diesel motor, with adapted control.

Nine examples of this locomotive were built for a single Canadian customer – Iron Ore Company of Canada (IOC).[1]
