Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The ALCO RSD-15 was a diesel-electric locomotive of the road switcher type built by ALCO 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 The RSD-15 was powered by an ALCO 251 16-cylinder four-cycle V-type prime mover rated at 2,400 horsepower; it superseded the almost identical ALCO 244-engined RSD-7, and was catalogued alongside the similar but smaller 1,800 hp RSD-12, powered by a 12-cylinder 251-model V-type diesel engine. 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.
