Parts of the Electro-Motive Diesel SD70M-2. Today is a great time to be a model railroader. The market is filled with a variety of locomotives from different manufacturers in many popular modeling scales. These engines often feature railroad- (and sometimes road-number-) specific details; factory-installed and painted wire grab irons; and sounds recorded from the prototype.

I reviewed the Athearn Genesis HO scale Electro-Motive Diesel SD70M-2 in the September 2022 issue of Model Railroader. As I was working on the review and comparing the model against prototype photos and drawings, I wanted to learn more about the different parts of the Electro-Motive Division SD70M-2. “What are those doors for?” and “Why are there screens there?” were just a few of the questions I asked myself.

In the following six images, I’ve called out some of the major details on the Athearn Genesis HO scale Electro-Motive Diesel SD70M-2 diesel locomotive. If you want to see a video of the model in action, watch the following video on Trains.com.

The conductor’s side of the SD70M-2 has injection-molded plastic inverter cabinet behind the cab and an etched-metal air compressor compartment grill toward the rear of the long hood.

Roof

An antenna dome, cast-metal air horn, and see-through cooling fan screens are some of the details on the roof of the modern diesel.

Cab interior

The cab roof is secured with magnets, providing access to the interior. Most railroads use two-person crews, so the third seat is rarely occupied.
