Locomotive, Diesel, Alco RS-2

History: The ALCO RS-2 is a 1,500–1,600 horsepower (1,100–1,200 kW) B-B road switcher diesel-electric locomotive built by the American Locomotive Company (ALCO) from 1946 to 1950. ALCO introduced the model after World War II as an improvement on the ALCO RS-1. The locomotive was one of several road switchers in a crowded market, including the Baldwin DRS-4-4-1500, EMD GP7, and FM H-15-44. ALCO discontinued the RS-2 in 1950 in favor of the ALCO RS-3. Several examples have been preserved.

383 locomotives were produced — 374 by the American Locomotive Company, and 9 by Montreal Locomotive Works in Canada. Eight of the ALCO RS-2s were exported to Canada. The RS-2 has a single, 12 cylinder, model 244B engine, developing 1,500 horsepower (1,100 kW). Thirty-one locomotives built by Alco between February and May 1950 with the 12 cylinder 244C 1,600 horsepower (1,200 kW) engine.
