The EMD SD75M and EMD SD75I are a series of diesel-electric locomotives produced by General Motors Electro-Motive Division between 1994 and 1996. The series is an improvement and extension to the EMD SD70 series, which further is an extension to the EMD SD60.
These locomotives shared its microprocessor with the EMD SD70 & SD60.
These locomotives were built as a response to General Electric's Dash 9-44CW, where as their cousins, the SD70MAC, were built in response to General Electric's AC4400CW. 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.
