Introduced in 1992, the EMD SD70M was a 4,000 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 SD40-2s to pull.
The DC brother of the SD70MAC, the SD70M was primarily put to work hauling coal trains due to its high pulling capacity. ESU LokSound V5 Micro Sound Decoder 58941. Dual mode DC or DCC operation. HTCR Phase II style trucks. Case cover is cracked (see photos).
