In The Box
  • (1) N Alco RSD-7 Locomotive


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, Broadway Limited is offering models of the RSD-15's in N scale with DCC and Sound for the first time. BLI is offering models of RSD-15's from 9 railroads in 10 distinct paint schemes. All road numbers and paint schemes are prototypically accurate. They are also building three models that were very similar in real life - two C and O RSD-7's and a CP RSD-17. The models will be BLI RSD-15 models with the C and 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.
