American Locomotive Company (Alco, ALCO or ALCo) was a locomotive manufacturing company that existed from 1901 to 1969. It also owned a Canadian subsidiary, Montreal Locomotive Works (MLW), which existed from 1882 to 1995.
The ALCO name still exists today but is owned by a completely different modern-day company.
History[]
ALCO was a conglomeration of several smaller locomotive manufacturing companies into one corporation. The companies merged included the Brooks Locomotive Company, Cooke Locomotive and Machine Company, Dickson Manufacturing Company, Manchester Locomotive Works, Pittsburgh Locomotive and Car Works, Rhode Island Locomotive Works, Richmond Locomotive Works, and the Schenectady Locomotive Works. The company was headquartered and founded in Schenectady, New York and produced over 150 different types of steam, diesel, and electric locomotives. They also exported many different locomotives to foreign countries. They've also produced some of the largest steam locomotives ever built, as well as powerful turbine locomotive types with General Electric (GE) during World War 2 (their long-term affiliate) and have had many numerous locomotives rebuilt from the Morrison-Knudsen company due to their partnership with the MLW (Montreal Locomotive Works) until 1995.
