EMD SW1200MG
Encyclopedia
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. 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).
