General Motors Diesel

General Motors Diesel was a railway diesel locomotive manufacturer located in London, Ontario, Canada. It served many notable companies such as BNSF Railway and Union Pacific.

General Motors Diesel, Limited, was created in 1949 as the Canadian subsidiary of the Electro Motive Division of General Motors located in the United States. Tariffs protected Canadian manufacturers against imported goods, thus many companies wanting to do business in Canada set up controlled or wholly owned subsidiaries in Canada.

Montreal Locomotive Works (MLW) in Montreal, Quebec, was created for just this reason building steam locomotives and later diesel (diesel-electric) locomotives to the designs of U.S. parent Alco (American Locomotive Company). Likewise, the Canadian Locomotive Company (CLC) in Kingston, Ontario built steam and diesel locomotives to their own designs, and those of other manufacturers such as Baldwin Locomotive Works and later Fairbanks-Morse.

Diesel-electric locomotives were built in Canada beginning in 1928 and continuing to the present. The earliest diesels were custom built one-of-a-kind designs such as Canadian National Railways numbers 9000 and 9001 and Canadian Pacific Railway number 7000. After these unique locomotives, the railways turned to more traditional designs built in the US and imported to Canada such as the Alco S-2 and EMD NW2 (both 1,000 hp) yard switchers.
