EMD NW3

The EMD NW3 was a 1,000 horsepower diesel-electric road switcher built by General Motors Electro-Motive Division at La Grange, Illinois, between November 1939 and March 1942. Seven were built for the Great Northern Railway, its only original buyer, and were numbered 5400 to 5406 before being renumbered 175 to 181. Fundamentally it combined an NW2 hood, a V12 EMD 567 engine and main generator on a long frame with Blomberg B road trucks, and the extra length held a large cab and a full-width hood section with a steam generator for passenger service. The units wore Great Northern black and later the orange and green Empire Builder colours. Four were traded back to EMD in 1965; the others went to industrial and short line owners, and the former Anaconda Aluminum unit is displayed at the Whitefish, Montana depot.
