In 1935, General Motors Electro Motive Division offered a 600hp switcher powered by it's 503cid '201' engine. Developement of the 201 resulted in a 12 cylinder version capable of delivering 900hp, and embracing General Electric traction motor technology in 1939, EMD issued the NW1 - N for nine hundred horsepower, W for welded
frame.

The same year, production of the 201 engine ceased with the introduction of the 567cid power unit; and EMD issued the first switcher powered by the new engine, the SW1. The S originally stood for six hundred horsepower, but this convention was dropped for later models. The 6 cylinder SW1 remained in production until 1953.

In October 1949, the SW7 model, a 12 cylinder, 1200 horsepower version was issued, and 493 units were constructed before the introduction of the SW9 in Jan. 1951.

From 1954, EMD issued the 600hp SW600, 900hp SW900, and the 1200hp SW1200, powered by 6, 8 and 12 cylinder configurations of the 567C power unit respectively. Production of the 567 ceased in 1966, with the introduction of the 645cid engine, which powered the later SW1000, SW1500 and their derivatives.
