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.[citation needed] By increasing up the output of the 16-710-G3 engine from 4,000 to 4,300 horsepower (3,000 to 3,200 kW), the engine becomes a player in the locomotive industry. The unit can be distinguished from EMD's SD70M by the added bulge below the inertial air-intake on 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 has an "Isolated Cab" which reduces noise and vibration in the cab from the engine. Both models use the HTCR-II radial truck and are mounted on the 72-foot-4-inch (22.05 m) frame. This model only sold 76 units and was not as popular as the SD70. The biggest buyer of this model was the Atchison, Topeka and Santa Fe Railway, now Burlington Northern Santa Fe, with 51 units; an additional 25 were lettered for BNSF in early 1996, during the merger process.

Mainly built for a special request from Santa Fe, the SD75M's are slightly more powerful than SD70M's, having horsepower ratings between 4,300 hp (3,200 kW) & 4500 hp. They are almost identical to SD70Ms, but can be distinguished by the added bulge below the inertial air-intake on the right side of the unit.
