176-7614 EMD SD70M Flat Radiator Norfolk Southern 2586Introduced in 1992, EMD SD70M was a 4000 horsepower locomotive that ran on EMDs 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.
