EMD SW1200 Diesel-Electric Locomotive
An EMD SW1200 is a diesel switcher locomotive built by General Motors Electro-Motive Division between January 1954 and May 1966. Power was provided by an EMD 567C 12-cylinder engine which generated 1,200 hp (895 kW). Late SW1200s built in 1966 were built with the 567E 12-cylinder engine. Additional SW1200 production was completed by General Motors Diesel in Ontario Canada between September 1955 and June 1964.
737 examples of this locomotive model were built for American railroads, 287 were built for Canadian railroads 4 were built for Brazilian Railroads, 25 were built for a Chilean Industrial firm, and 3 were built for the Panama Canal Railway.
A cow-calf variation, the TR12, was cataloged, but none were built.
A few units were built with dynamic brakes, featuring large square box with a fan on top of the hood, right in front of the cab.
An SW1200RS is a variation of the standard SW1200 that featured large front and rear (on some units) numberboard housings, EMD Flexicoil B-B trucks, and larger fuel tanks for road switcher service. The majority of the Canadian National and Canadian Pacific SW1200 fleets were purchased as SW1200RS units. The Sandersville Railroad Company EMD SW1200 road number SAN 1200 formerly SAN 200 was originally built with the V-12 EMD 567C Prime Mover but it was replaced with a V-12 EMD 645 Prime Mover, the two both produce 1,200 Horsepower, even though the same motor in the EMD SW1500 produces 1,500 Horsepower. The SAN 1200 also has EMD Flexcoil trucks instead of the standard switcher trucks found on other EMD SW1200s.

GMD SW1200MG Electric Locomotive
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).
