SD70M-2 w/Proto Sound 3.0

Canadian National  No. 8000

Awesome, eh?

The standard bearers for EMD, newly independent and no longer a division of General Motors, are its 70 Series road freight engines, the SD70M-2 (shown here) and the SD70ACe.

Both locomotives are powered by a two-cycle, 16-cylinder, 4300-horsepower model 710 prime mover and have a top speed of 70 mph.

The biggest difference between the siblings is what's under the floor: traditional DC traction motors in the SD70M-2's trucks and AC traction motors in the SD70ACe

While AC traction motors put more tractive effort on the rails and enable an SD70ACe to start a heavier train with the same horsepower, that additional capability comes at a cost.

AC-powered locomotives are both more expensive and more electrically complex than engines with DC traction motors, which most diesels have used since the 1940s.

For that reason, the Norfolk Southern and Canadian National have found the SD70M-2 more suitable to their needs, and both roads roster large DC fleets.

Regional railroad Florida East Coast has been another DC-power advocate.

With MTH's unique Proto-Sound 3.0 sound and control system, these highly detailed models offer a broader range of features than you'll find on any other HO scale diesel, including flashing ditch lights; smooth performance from a three-scale-mile-per-hour crawl to full throttle; "cruise control" for steady speeds regardless of curves, switches and grades; built-in decoders for DCC and the MTH Digital Command System (DCS); and a full range of prototypical EMD sounds.

Proto-Sound 3.0 equipped locomotives can be controlled in command mode with any DCC compliant command control system.

While the user won't have access to all of the incredible features of Proto-Sound 3.0, independent control over the locomotive is possible.

This means you can continue to use your existing DCC controller to independently control your other DCC equipped locomotives in addition to your Proto-Sound 3.0 locomotive on the same track at the same time.
