The EMD NW2 is a 1,000 hp (750 kW), B-B switcher locomotive manufactured by General Motors Electro-Motive Division of La Grange, Illinois. The NW2 was manufactured from February 1939 to December 1949, and 1145 were produced – 1121 for the U.S., and 24 were exported to Canada. Starting in late 1948 the NW2s were manufactured in EMD's Plant #3 in Cleveland, Ohio. The 1,000 hp (750 kW) was achieved by using a 12-cylinder, model 567, and later, a model 567A engine. In addition, 3 TR cow-calf paired sets, 36 TR2 cow-calf paired sets, and 2 TR3 cow-calf-calf sets were produced. The TR sets were built prior to World War II and the TR2 and TR3 sets were built postwar.
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.
Many NW2's survive today. One NW2 is operated by the Midland Railway in Baldwin City, Kansas. It is privately owned. It is ex-Chicago, Burlington and Quincy Railroad #9227. It is used mainly for work trains. The Elgin, Joliet and Eastern Railway of Illinois and Indiana operates an NW2 cow/calf unit in its Joliet railyard. The Indiana Harbor Belt who operated near 80 still operates two.
Lake Superior Terminal and Transfer Railway 101 is unrestored at the Minnesota Transportation Museum.
