EMD SD7

Diesel and Electric Locomotives

The EMD SD7 is a six-axle diesel locomotive built by General Motors Electro-Motive Division from May 1951 to November 1953 and was the first model of EMD's SD, or Special Duty, series. It was conceived as a lengthened GP7 with a C-C truck arrangement, and an EMD 567B 16-cylinder engine producing 1,500 horsepower drove its six traction motors. The extra axles gave more tractive effort and spread weight more evenly, which suits heavy, low-speed freight work. American railroads bought 188 units. The SD9 succeeded it in January 1954, and the Southern Pacific rebuilt 42 of its SD7 locomotives.
