Introduced in 1992, EMD SD70M was a 4000 horsepower locomotive that ran on EMD’s new steerable truck design, known as the HTCR-II radial truck. This new truck allowed the locomotive to transfer its power to the rails more efficiently, which in turn enabled two SD70M locomotives to pull a train that would have taken 3 SD40-2’s to pull. The DC brother of the SD70MAC, the SD70M was primarily put to work hauling coal trains due to its high pulling capacity.
These models will be equipped with all-wheel electrical pick-up and blackened metal wheels in trucks that replicate the HTCR Phase II trucks.
