The GMD GMDH-3 was an experimental diesel-hydraulic switching locomotive built in January 1960 by General Motors Diesel of Canada. Only one example was built, with GMD serial number A1813. The locomotive was essentially the GMDH-1 design but with only a single hood, a single engine and an end cab, mounted on a six-wheel chassis.

The locomotive served as a demonstrator for GMD, bearing number #275, between 1960 and 1962, including a period in Egypt, but no sales resulted. The locomotive was sold in 1963 to McKinnon Industries of St. Catharines, Ontario as their plant switcher, #2128. After nearly 30 years of service, it was sold in 1992 to the South Simcoe Railway, a heritage museum railway, in Tottenham, Ontario, but in 1995 it was declared surplus to requirements by the railway's directors. After a fund-raising effort, the Southern Michigan Railroad Society purchased the locomotive in 1996, where it remains in operable condition as of 2006. As of June 2015, GMDH-3 had been repainted in two-tone blue, and is still parked in Clinton, MI awaiting funds for restoration.
