Prototype History: The ALCO RSD-15 was a diesel-electric locomotive of the road switcher type built by ALCO (the American Locomotive Company) of Schenectady, New York between August 1956 and June 1960, during which time 75 locomotives were produced. The RSD-15 was powered by an ALCO 251 16-cylinder four-cycle V-type prime mover rated at 2,400 horsepower (1.79 MW); it superseded the almost identical ALCO 244-engined RSD-7, and was catalogued alongside the similar but smaller 1,800 hp (1.34 MW) RSD-12, powered by a 12-cylinder 251-model V-type diesel engine.
A single example of the very similar model RSD-17 was built by the Montreal Locomotive Works in 1957 and purchased by the Canadian Pacific (as #8921).

The locomotive rode on a pair of three-axle Trimount trucks, in an AAR C-C wheel arrangement, with all axles powered by General Electric model 752 traction motors. These trucks have an asymmetrical axle spacing because of the positioning of the traction motors. The six-motor design allowed higher tractive effort at lower speeds than an otherwise similar four-motor design. The RSD-15 could be ordered with either a high or low short hood; railfans dubbed the low short hood version "Alligators", on account of their unusually long low noses.
