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 prime mover rated at 2,400 hp (1,800 kW).
It superseded the very similar in appearance ALCO 244-engined RSD-7, and was cataloged alongside the similar but smaller 1,800 hp (1,350 kW) RSD-12.
The locomotive rode on a pair of three-axle trucks with all three axles on each truck powered; this is known as a C-C wheel arrangement.
These trucks have an unequal axle spacing due to traction motor positioning; the outer two axles on each truck are closer together than the inner two.
The six-motor design allowed better tractive effort at lower speeds.
The RSD-15 could be ordered with either a high or low short hood; railfans dubbed the low short hood version "Alligators" because of their long noses.
