EMD SD75M/SD75I

The EMD SD75M and EMD SD75I are series of similar 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 4,000 to 4,300 horsepower (3,000 to 3,200 kW), 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. In September 2014, Norfolk Southern purchased 7 SD75Ms via National Railway Equipment Company.
