GMD GMD-1 Locomotives
The GMD GMD-1 is a diesel locomotive originally produced by General Motors Diesel (GMD), the Canadian subsidiary of General Motors Electro-Motive Division, between August 1958 and April 1960. This Road switcher locomotive is powered by a 12-cylinder EMD 567C diesel engine, capable of producing 1,200 horsepower (890 kW). The GMD-1 was built on either Flexicoil A1A-A1A (for light rail prairie branchlines) or Flexicoil B-B trucks. 101 examples of this locomotive were built for Canadian railways. 96 went to Canadian National Railway and the remaining 5 went to Northern Alberta Railways (that later became part of CN's fleet when they acquired majority interest in NAR).
