EMC - EMD NW2 DIESEL-ELECTRIC SWITCHER LOCOMOTIVE

The EMD NW2 is a 1,000 hp (750 kW), B-B switcher locomotive manufactured by EMC and later General Motors Electro-Motive Division of La Grange, Illinois. From February 1939 to December 1949, EMD produced 1,145 NW2s: 1,121 for U.S. and 24 for Canadian railroads. Starting in late 1948, the NW2s were manufactured in EMD's Plant No. 3 in Cleveland, Ohio. The locomotives were powered by a 12-cylinder model 567 engine and later a model 567A engine. In addition, EMD built three TR cow-calf paired sets, 36 TR2 cow-calf paired sets, and two TR3 cow-calf-calf sets. The TR sets were built before World War II; the TR2 and TR3 sets afterward.

Identification

Distinguishing features include two stacks in the middle of the hood, a half-height radiator grille, no sand box on the front platform, and no small louvers at the top front corners of the sides of the hood. The predecessor of the NW2 was the NW1. The "N" in NW1 stands for the nine in nine hundred hp (670 kW). The "W" in both models stands for "welded frame".

M-K-T EMD NW2 No. 1029 (built in 1947) at the Wichita Falls Railroad Museum, Wichita Falls, TX.
