The EMD SD75M is a series of diesel-electric locomotives produced by General Motors Electro-Motive Division in 1994. The series was a response to General Electric's Dash 9-44CW. By bumping up the output of the 16-710-G3 engine from 4000 to 4300 horsepower, the SD75 was a reality. The unit is recognized from the SD70 by the added bulge below the inertial air-intake one the right side of the unit. The "M" in the model designation is the style of the cab, in this case the North American style cab. The SD75I had a "WhisperCab" in EMD speak. Both models use the HTCR-II radial truck and are mounted on the 72 feet 4 inch frame. This model only sold 76 units and was not as popular as the SD70. The biggest buyers of this model were the Santa Fe, now Burlington Northern Santa Fe.
