Introduction

Athearn RTR 1431 HO Scale EMD SD38 McCloud River Railroad MR 38 DC

The SD38 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between May 1967 and October 1971. It had an EMD 645 16-cylinder engine generating 2,000 horsepower. The EMD SD38AC built by General Motors Electro-Motive Division between June and October 1971. It was basically an SD38 with an AR10 alternating current alternator instead of the SD38s normal direct current generator. It also produces 2,000 horsepower from a 16-cylinder EMD 645E roots blown prime mover. It came equipped with or without dynamic brakes. The SD38 and SD38AC have the same frame as the SD39, SD40 and SD45.

In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. The SD39 had 2,300 hp from a turbocharged V12. The SD39 had the smallest prime mover of the SD locomotives in the EMD catalog. 54 were built for American railroads.
