The Alco RSD-15’s were built between 1956 and 1960 in Schenectady, New York.  The RSD-15 was powered by an Alco 251 16-cylinder V-type engine.   Rated at 2,400 horsepower, these versatile locomotives were suited for mainline freight and passenger service.  The locomotive rode on 3-axle trucks with all axles powered by GE model 752 traction motors.  The trucks have asymmetrical axle spacing because of the position of the traction motors.  The six-motor design allowed for higher tractive effort at lower speeds than a similar four-motor design. 

The RSD-15’s could be ordered with either a high or low short hood, and the low hood versions quickly earned the nickname “alligators” due to their unusually long noses. 

In 2022, we are offering models of the RSD-15’s in N scale with DCC & Sound for the first time.  We are offering models of RSD-15’s from 9 railroads in 10 distinct paint schemes.   All road numbers and paint schemes are prototypically accurate.  We are also building three models that were very similar in real life – two C&O RSD-7’s and a CP RSD-17.   The models will be BLI RSD-15 models with the C&O and CP paint schemes applied.   There wasn’t a lot of detail variation among the RSD-15’s, and we are making three distinct models – a standard low-hood model, a standard high-hood model, and a PRR-type high hood model with different locations for the bell and horns. 

Independently controllable lights in each RSD-15 model:

  • Headlight
  • Rear Light
  • Cab Light
  • Front & Rear Numberboards
