This locomotive was the electric version of the diesel powered SW1200, with the prime mover replaced by amotor-generator set, hence the MG suffix in the model number.Locomotives run under 2400V 60 Hz, in automatic control without driver. 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 –
