McIntosh & Seymour 330

Locomotive Engines

The McIntosh & Seymour 330 was an early diesel prime mover built by McIntosh & Seymour at Auburn, New York, the engine maker that the American Locomotive Company (Alco) acquired after leaving its 1920s boxcab partnership with General Electric and Ingersoll Rand. It powered the first ALCO boxcab switcher, outshopped in January 1931 and sold after a brief demonstration tour to Jay Street Connecting, and two end cab switchers built in early 1931. Those early switchers led Alco to build its HH series around the larger McIntosh & Seymour 531 engine, with General Electric electrical equipment, by mid-1931. The 330 itself stayed in production at Auburn into the late 1930s.
