By the summer of 1950 General Motors Diesel was producing locomotives with the first completed being Toronto, Hamilton & Buffalo GP7 #71 that August. A month later GMD finished what was actually the first order received by the plant, Canadian Pacific FP7s #4028-4037, which were delivered in September. Considering Electro-Motive's success in the American market it's not considerably shocking that GMD also did quite well producing most of its parents designs including the F7, FP7, FP9, F9, GP7, GP9, GP30, SW8, SW900, SW9, SW1200, MP15AC, GP38/-2/W, GP40/-2/TC, SD40/-2, SD38-2, and others. It also built locomotives only used in Canada such as the GMD-1 (a light road-switcher that resembled Alco's RS-1) and cowl designs of popular Geeps and Special Duty (SD) models that were uncommon in the U.S.
During the 1960s the London plant also began producing other equipment such as transit buses, suburban coaches, and heavy earthmoving equipment. On February 1, 1969 GM began restructuring Canadian operations and renamed GMD as the Diesel Division of General Motors of Canada, or General Motors Diesel Division (GMDD) for short. As time passed GM began shifting more production to London, particularly as General Electric became a serious competitor during the 1970s. Within a decade GE had claimed top spot as locomotive manufacturer when EMD stumbled with its SD50 model in 1981 (which was supposed to be the builder's next generation of road-switcher).

In 1991 as EMD continued to lose market share to GE it shuttered its
famous La Grange, Illinois plant and shifted all production to London under
the North American Free Trade Agreement (NAFTA), which essentially
abolished the General Motors Diesel Division name. Ironically,
things would come full circle within 20 years. In 2005 GM exited the
locomotive market, selling its EMD subsidiary to investment groups,
which renamed it as Electro-Motive Diesel, Inc. Five years later on
August 2, 2010 Progress Rail Services Corporation, a Caterpillar
subsidiary, took controlling interest in EMD. During early 2012 a
long-time contract dispute with CAW workers at the former GMD facility
resulted in Caterpillar closing the plant and moving all operations to
Muncie, Indiana thus ending continuous production in London after 60
years of operation.
