NS 2800-2806. | builder=General Motors Electro-Motive Division (EMD) | buildmodel=SD75M | builddate=1994 – 1996 }} The EMD SD75M is a series of road switcher diesel-electric locomotives produced by General Motors Electro-Motive Division between 1994 and 1996. The series was a response to General Electric's Dash 9-44CW. By increasing the output of the 16-710-G3 engine from {{convert|4000|to|4300|hp}}, the SD75 was a reality. 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", or a "WhisperCab" in EMD speak, which reduces noise and vibration in the cab. Both models use the HTCR radial truck and are mounted on the {{convert|72|ft|4|in|m|adj=on}} 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 delivered in early 1996, during the merger process. The Santa Fe's SD75Ms were the railroad's last new locomotives, with the very last new unit, number 250, built in August 1995.[2] Mainly built for a special request from Santa Fe/BNSF, the SD75Ms are slightly more powerful than SD70Ms, having horsepower ratings between {{convert|4300|hp|abbr=on}} & 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. In September 2014, Norfolk Southern purchased 7 SD75Ms via National Railway Equipment Company.[3] Current and Former operators
