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.
The ALCO Century Series locomotives were a line of road switcher locomotives produced by Alco, the Montreal Locomotive Works and AE Goodwin under license in Australia.
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.
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 Diesel 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 ALCO RS-3 is a 1,600 hp (1.2 MW), B-B diesel-electric locomotive manufactured from May 1950 to August 1956 by American Locomotive Company (ALCO) and its subsidiary Montreal Locomotive Works (MLW). A total of 1,418 were produced: 1,265 for American railroads, 98 for Canadian railroads, 48 for Brazilian railroads, and seven for Mexican railroads.
The ALCo Century 636 was the most powerful single-engine diesel-electric locomotive constructed by the American Locomotive Company (ALCo). It used their 251 prime mover. The locomotive had a C-C wheel arrangement and 3,600 horsepower (2,700 kW). The locomotive rode on a pair of trucks of all-new design, known as the Hi-Ad, standing for 'high adhesion'. Visually, it is similar to the Century 630, but can be distinguished by the intercooler box. The C630 has two grilles here, one above the other. The C636 only has the upper grille.
The ALCO Century 630 is a model of six-axle, 3,000 hp (2.2 MW) diesel-electric locomotive built by the American Locomotive Company (ALCO) between 1965 and 1967. It used the ALCO 251 prime mover. 77 were built: 3 for Atlantic Coast Line Railroad, 4 for Chesapeake and Ohio Railway, 8 for Louisville and Nashville Railroad, 10 for Norfolk and Western Railway, 15 for Pennsylvania Railroad, 12 for the Reading Company, 15 for Southern Pacific Railroad and 10 for Union Pacific Railroad.
The ALCO S-1 and S-3 were 660 horsepower (490 kW) diesel-electric switcher locomotives produced by ALCO and their Canadian subsidiary Montreal Locomotive Works (MLW). The two locomotives differed only in trucks, with the S-1 using ALCO's own Blunt trucks, and the S-3 using AAR type A switcher trucks. The S-1 was built between April 1940 and June 1950, with a total of 543 completed, while the S-3 was constructed between February 1950 and November 1953 with total sales of 300. A modified version, the S-10, was built by MLW only; 13 were built between January and June 1958.
The ALCO RS-11 is a class of diesel-electric locomotive rated at 1,800 hp (1.34 MW), that rode on two-axle trucks, having a B-B wheel arrangement. This model was built by both Alco and Montreal Locomotive Works. Total production was 426 units.
The ALCO RSC-3 was a diesel-electric locomotive of the road switcher type rated at 1,600 horsepower (1,200 kW), that rode on three-axle trucks, having an A1A-A1A wheel arrangement.
The ALCO RSD-15 is a diesel-electric locomotive built by the American Locomotive Company (ALCO) of Schenectady, New York between August 1956 and June 1960, during which time 75 locomotives were produced. The RSD-15 was powered by an ALCO 251 16-cylinder four-cycle V-type prime mover rated at 2,400 horsepower (1.79 MW); it superseded the almost identical ALCO 244-engined RSD-7, and was catalogued alongside the similar but smaller 1,800 hp (1.34 MW) RSD-12, powered by a 12-cylinder 251-model V-type diesel engine.
The ALCO RS-2 is a 1,500–1,600 horsepower (1,100–1,200 kW) B-B diesel-electric locomotive built by the American Locomotive Company (ALCO) from 1946 to 1950. ALCO introduced the model after World War II as an improvement on the ALCO RS-1. Between 1946 and 1950, 377 examples of the RS-2 were built, primarily for American and Canadian customers.
The MLW RSC-24 was a type of diesel-electric locomotive built by Montreal Locomotive Works for use on the Canadian National Railway (CN).
The ALCO S-2 and S-4 are 1,000-horsepower (746 kW) diesel electric switcher locomotives produced by ALCO and Canadian licensee Montreal Locomotive Works (MLW).
The Century 424 was a four-axle, 2,400 hp (1,790 kW) diesel-electric locomotive. 190 were built between April 1963 and May 1967. Cataloged as a part of Alco's Century line of locomotives, the C424 was intended to replace the earlier RS-27 model and offered as a lower-priced alternative to the C425. Montreal Locomotive Works also built this locomotive as MLW Century 424.
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 Bombardier HR616, also known as the MLW HR616, was a 6 axle, 3,000 horsepower (2.2 MW) freight locomotive manufactured in Montreal, Quebec, Canada. Twenty were built for Canadian National Railway in 1982, numbered 2100–2119, with 2100–2103 being temporarily renumbered as Bombardier 7000–7003, and rated at 3,200 hp (2.4 MW) for demonstration of the new model on Canadian Pacific Railway in 1983. After the demonstration, they were returned to CN and reverted to their original 2100–2103 numbers.
The MLW RS-18 was an 1,800 hp (1,340 kW) diesel-electric locomotive built by Montreal Locomotive Works between December 1956 and August 1968. It replaced the RS-10 in MLW's catalogue, and production totalled 351 locomotives, to eight customers.
The Bombardier HR-412, also known as the MLW HR-412, was a 4 axle, 2,400 horsepower (1.8 MW) freight locomotive manufactured in Montreal, Quebec, Canada. Ten were built for Canadian National Railway in between September and November 1981, numbered 2580–2589, and one was built for Bombardier as a demonstrator in May 1982, numbered BBD 7000. BBD 7000 was later sold to Canadian National.
The class YDM-4 is Indian Railways' workhorse diesel locomotive. The first units were imported fully built from the American Locomotive Company (Alco) in 1961. Since 1968, it has been manufactured in India by the Banaras Locomotive Works (BLW), Varanasi. The model name stands for metre gauge (Y), diesel (D), mixed traffic (M) engine. The YDM-4 has been the most successful diesel locomotive in the metre gauge operation of Indian Railways. The YDM-4A is a variant of the YDM-4 supplied by MLW. Originally equipped with vacuum brakes. Some were later equipped with dual brakes, particularly those working in the Northeast Frontier Railway were retrofitted with dual brake system by Lumding shed. The YDM-4 locos have a maximum speed of 100 km/h (62 mph), restricted to 85 km/h (53 mph).
