The ALCO RSD-15 is a American locomotive class.

HistoryEdit

Built by the American Locomotive Company between August 1956 and June 1960, 75 locomotives were produced.

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 due to 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.
