General Motors Diesel Division (GMDD) was a marketing and customer service unit of General Motors founded in 1938. It sought customers for GM's diesel engines, which had undergone major development during the 1930s.It was most active in association with GM's Detroit Diesel Engine Division, which produced lines of lightweight diesel engines that could be adapted to many uses including road vehicles, small boats, military equipment, construction and farm equipment, pumping, and auxiliary power generation. In 1939, Detroit Diesel Series 71 engines were installed in buses produced by Yellow Coach, who would be acquired by GM in 1943 to launch the GMC Truck and Coach Division. Uses for Detroit Diesel engines would proliferate during World War II and the postwar economic boom. The GM Cleveland Diesel Engine Division's products were sold to relatively few customers for mostly marine uses. GMDD developed a widespread international marketing, service, and parts distribution infrastructure for GM diesel engines in the postwar years.
In 1962 GM's Electro-Motive Division (EMD), which had its own marketing and service infrastructure from its years in the locomotive business, took over the production and marketing of large diesel engines formerly produced by the Cleveland Diesel Engine Division.
In 1965 GMDD was absorbed by the General Motors Detroit Diesel Engine Division.
General Motors Diesel Division is not to be confused with General Motors Diesel, Ltd., the Canadian subsidiary of EMD formed in 1949, or the Diesel Division of General Motors of Canada, the entity for General Motors of Canada's diesel equipment manufacturing operations formed in 1969.

General Motors Diesel was a railway diesel locomotive manufacturer located in London, Ontario, Canada. It was established in 1949 as the Canadian subsidiary of the Electro Motive Division of General Motors (EMD). In 1969 it was re-organized as the Diesel Division of General Motors of Canada, Ltd. The plant was re-purposed to include manufacture of other diesel-powered General Motors vehicles such as buses. Following the Canada-United States Free Trade Agreement in 1989, all of EMD's locomotives were built at the London facility. In 2005 new owners of EMD renamed the Canadian subsidiary Electro-Motive Canada. The plant was closed by EMD's new owner Progress Rail in 2012, with EMD's production remaining in LaGrange, Illinois and Muncie, Indiana.
The EMD FT is a 1,350-horsepower (1,010 kW) diesel-electric locomotive that was produced between March 1939 and November 1945, by General Motors' Electro-Motive Corporation (EMC), later known as GM Electro-Motive Division (EMD). The "F" stood for Fourteen Hundred (1400) horsepower and the "T" for Twin, as it came standard in a two-unit set. The design was developed from the TA model built for the C,RI&P in 1937, and was similar in cylinder count, axle count, length and layout. All told 555 cab-equipped ”A” units were built, along with 541 cabless booster or ”B” units, for a grand total of 1,096 units. The locomotives were all sold to customers in the United States. It was the first model in EMD's very successful F-unit series of cab unit freight diesels, and was the locomotive that convinced many U.S. railroads that the diesel-electric freight locomotive was the future. Many rail historians consider the FT one of the most important locomotive models of all time.

It succeeded the F7 model in GM-EMD's F-unit sequence. Final assembly was at GM-EMD's La Grange, Illinois plant. The F9 was also built in Canada by General Motors Diesel at their London, Ontario plant. A total of 101 cab-equipped lead A units and 156 cabless booster B units were built. The F9 was the fifth model in GM-EMD's highly successful "F" series of cab unit diesel locomotives.
The EMD SD50 is a 3,500-horsepower (2,610 kW) diesel-electric locomotive built by General Motors Electro-Motive Division. It was introduced in May 1981 as part of EMD's "50 Series", but prototype SD50S locomotives were built from 1980; production ceased in January 1986. The SD50 was in many respects a transitional model between EMD's Dash 2 series which was produced throughout the 1970s and the microprocessor-equipped SD60 and SD70 locomotives.

The Cleveland Diesel Engine Division of General Motors (GM) was a leading research, design and production facility of diesel engines from the 1930s to the 1960s that was based in Cleveland, Ohio. The Cleveland Diesel Engine Division designed several 2 stroke diesel engines for submarines, tugboats, destroyer escorts, Patapsco-class gasoline tankers and other marine applications. Emergency generator sets were also built around the Cleveland Diesel and were installed in many US warships. The division was created in 1938 from the GM-owned Winton Engine Corporation and was folded into the GM Electro-Motive Division in 1962. The engines continue in use today on older tugs.
