The M-636 was a six-axle, 3,600 hp diesel locomotive marketed as part of the Montreal Locomotive Works six-axle "M-Line" series of locomotives. It was essentially the Canadian-built version of the ALCO Century 636 , and it saw many sales to Canadian, Mexican and Australian customers. Today, there are a handful M-636s left in revenue service.

The American Locomotive Company was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller locomotive manufacturers and Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962.
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.
The ALCO Century 415 was a diesel-electric locomotive of B-B wheel arrangement produced by the American Locomotive Company (ALCO) as part of their Century Series of locomotives.
Montreal Locomotive Works (MLW) was a Canadian railway locomotive manufacturer which existed under several names from 1883 to 1985, producing both steam and diesel locomotives. For a number of years it was a subsidiary of the American Locomotive Company. MLW's headquarters and manufacturing facilities were in Montreal, Quebec.
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) switcher diesel-electric 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 RS-1 was a 4-axle diesel-electric locomotive built by Alco-GE between 1941 and 1953 and the American Locomotive Company from 1953 to 1960. ALCO subsidiary Montreal Locomotive Works built an additional three RS-1s in 1954. This model has the distinction of having the longest production run of any diesel locomotive for the North American market. The RS-1 was in production for 19 years from the first unit Rock Island #748 in March 1941 to the last unit National of Mexico #5663 in March 1960.
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 S-2 and S-4 were 1,000-horsepower (746 kW) diesel electric switchers 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 Alco T6 was a diesel-electric locomotive of the switcher type rated at 1,000 horsepower (750 kW), that rode on two-axle trucks, having a B-B wheel arrangement.
AE Goodwin was an Australian heavy engineering firm, which produced railway locomotives and rolling stock, as well as roadmaking machinery at its factory in Auburn.
The MLW M-420 was a diesel-electric locomotive manufactured between 1973 and 1977 in Montreal, Canada by the Montreal Locomotive Works. A total of 88 units were built for Canadian railways, including eight B units built for the British Columbia Railway; most of production went to Canadian National. Only seven units were sold outside of Canada, to the State Railways Institution in Venezuela and the Providence and Worcester Railroad in the United States.
The Hamersley & Robe River railway, majority-owned by Rio Tinto, and operated by its subsidiary Pilbara Iron, is a private rail network in the Pilbara region of Western Australia for the purpose of carrying iron ore. The network is larger than any other Australian heavy freight rail network in private ownership. The total length of its track is about 1,700 km (1,056 mi).
