The American Locomotive Company was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
Montreal Locomotive Works (MLW) was a Canadian railway locomotive manufacturer that existed under several names from 1883 to 1985, producing both steam and diesel locomotives. For many years it was a subsidiary of the American Locomotive Company. MLW's headquarters and manufacturing facilities were in Montreal, Quebec.
The EMD GP30 is a 2,250 hp (1,680 kW) four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada, including 40 cabless B units for the Union Pacific Railroad.
The ALCO HH series was an early set of diesel switcher locomotives built by the American Locomotive Company (ALCO) of Schenectady, New York between 1931 and 1940, when they were replaced by the S series: the 660 hp (490 kW) S-1 and 1,000 hp (750 kW) S-2. They were ALCO's first diesel switchers to enter true series production, and among the first land vehicles anywhere to use the revolutionary diesel-electric power transmission.
The Consolidation Line was a series of diesel-electric railway locomotive designs produced by Fairbanks-Morse and its Canadian licensee, the Canadian Locomotive Company. Railfans have dubbed these locomotives “C-liners”, however F-M referred to the models collectively as the C-Line. A combined total of 165 units were produced by F-M and the CLC between 1950 and 1955.
Electro-Motive Diesel is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD is now owned by Progress Rail Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel.
The GE 44-ton switcher is a four-axle diesel-electric locomotive built by General Electric between 1940 and 1956. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores.
Before diesel engines had been developed for locomotive power in the 1920s and 1930s, many companies chose to use the gasoline engine for rail motive power. The first GE Locomotive was a series of four-axle (B-B) boxcab gasoline-electric machines closely related to the "doodlebugs", self-propelled passenger cars built in the early Twentieth Century.
A boxcab, in railroad terminology, is a North American term for a locomotive in which the machinery and crew areas were enclosed in a box-like superstructure. Deriving from "boxcar", the term mainly occurs in North America. It was also applied to Victorian Railways "E" class second series electric locomotives.
The Chicago, Milwaukee, St. Paul and Pacific Railroad classes EP-1 and EF-1 comprised 42 boxcab electric locomotives built by the American Locomotive Company (Alco) in 1915. Electrical components were from General Electric. The locomotives were composed of two half-units semi-permanently coupled back-to-back, and numbered as one unit with 'A' and 'B' suffixes. As built, 30 locomotives were assigned to freight service, classified as EF-1 and numbered 10200–10229. The remaining twelve locomotives were assigned to passenger service as class EP-1, numbered 10100–10111, with higher-speed passenger gearing. The design was highly successful, replacing a much larger number of steam locomotives, cutting costs and improving schedules. General Electric self-proclaimed this electric locomotive to be the “King of the Rails” in a silent promotional film from 1915.
The ALCO FA was a family of B-B diesel locomotives designed to haul freight trains. The locomotives were built by a partnership of ALCO and General Electric in Schenectady, New York, between January 1946 and May 1959. Designed by General Electric's Ray Patten, they were of a cab unit design; both cab-equipped lead FA and cabless booster FB models were built. A dual passenger-freight version, the FPA/FPB, was also offered. It was equipped with a steam generator for heating passenger cars.
The GE 45-ton switcher is a 4-axle diesel locomotive built by General Electric between 1940 and 1956.
The Union Pacific GTELs were a series of gas turbine-electric locomotives built by Alco-GE and General Electric between 1952-1961 and operated by Union Pacific from 1952 to 1970.
The ALCO 300 was an early diesel-electric switcher locomotive built by the American Locomotive Company (ALCO) of Schenectady, New York between 1931 and 1938.
The GE boxcabs, sometimes also GE IR boxcabs, were diesel-electric switcher locomotives succeeding the ALCO boxcabs. The locomotives were built by General Electric and Ingersoll Rand without ALCO. Production lasted from 1928 to 1930. These boxcabs were often termed oil-electrics to avoid the use of the German name Diesel, unpopular after World War I.
The GE three-power boxcabs were early electro-diesel hybrid switcher locomotives. These boxcabs were termed oil battery electrics to avoid the use of the German name Diesel, unpopular after World War I.
Maine Central Railroad began operating diesel locomotives in 1935, and had retired all steam locomotives by 1954. That time interval was a joint operating period with the Boston and Maine Railroad (B&M). This article describes diesel locomotives owned by Maine Central through the period of joint operation and later independent operation prior to Guilford Rail System control in 1981.
The Great Northern Z-1 was a class of ten electric locomotives built for the Great Northern Railway They were used to work the route through the second Cascade Tunnel. They were built between 1926–1928 by Baldwin Locomotive Works, with Westinghouse electrics, and stayed in service until dieselisation in 1956. Each was of 1,830 horsepower (1,360 kW) with a 1-D-1 wheel arrangement, although they were always used in coupled pairs.
