Available On: July 1, 2015

EMD introduced the SD50 in the early 1980s with a 16 cylinder, 3500 h.p. engine to attain the power that they had early gotten from a 20 cylinder locomotive. The new, longer frame allowed the dynamic brake resistors to be relocated to a cooler area found between the central air intake and the cab.
