EMD SD39
An SD39 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between August 1968 and May 1970. 54 were built for American railroads. In 1966 EMD replaced all their old models with new ones having the new 645 diesel. These included six-axle models SD38, SD40, SDP40 and SD45; the SD39 was added in 1968. All shared standard components including the frame, cab, traction alternator, trucks, traction motors, and air brakes. The difference was the power output: SD38 = from a non-turbocharged V16, SD39 = from a turbocharged V12, SD40 = from a turbocharged V16, and SD45 = from a turbocharged V20. The SD39 had the smallest prime mover and therefore had the most unused space above the frame, inside the hood between the main generator and electrical cabinet, and outside in large end "porches". ==Variant== A variant was the SDL39, ordered by the Milwaukee Road. Shorter and lighter than a stock SD39, these minimized weight per axle.
