GMD GMDH-3

The GMD GMDH-3 is an experimental diesel-hydraulic switching locomotive built in January 1960 by General Motors Diesel of Canada. Only one was ever built, with GMD serial number A1813. It was essentially the earlier GMDH-1 design reduced to a single hood, a single engine and an end cab on a six-wheel chassis. After completion it served as a GMD demonstrator numbered 275 and spent time in Egypt between 1960 and 1962, but no sales followed. In 1963 it was sold to McKinnon Industries of St. Catharines, Ontario, as plant switcher number 2128, and it worked there for nearly thirty years. It passed to the South Simcoe Railway in 1992 and was declared surplus in 1995, after which the Southern Michigan Railroad Society bought it in 1996 following a fund-raising effort. It remained in operable condition in 2006, was repainted in two-tone blue by 2015, and is parked in Clinton, Michigan, awaiting funds for restoration.
