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.

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 #3 in Cleveland, Ohio.

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 "N" in NW1 stands for the nine in nine hundred hp (670 kW).
