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.
A diesel locomotive is a type of railway locomotive in which the prime mover 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 Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation.
GE Transportation is a division of Wabtec. It was known as GE Rail and owned by General Electric until sold to Wabtec on February 25, 2019. The organization manufactures equipment for the railroad, marine, mining, drilling and energy generation industries. The company was founded in 1907. It is headquartered in Pittsburgh, Pennsylvania, while its main manufacturing facility is located in Erie, Pennsylvania. Locomotives are assembled at the Erie plant, while engine manufacturing takes place in Grove City, Pennsylvania. In May 2011, the company announced plans to build a second locomotive factory in Fort Worth, Texas, which opened in January 2013.
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 located in Montreal, Quebec.
The GE U25B was General Electric's first independent entry into the United States domestic road switcher diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco.
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 HH series were an early series of switcher diesel-electric 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 ALCO PA was a family of A1A-A1A diesel locomotives built to haul passenger trains. The locomotives were built in Schenectady, New York, in the United States, by a partnership of the American Locomotive Company (ALCO) and General Electric (GE) between June, 1946 and December, 1953. Designed by General Electric's Ray Patten, they were of a cab unit design; both cab-equipped lead A unit PA and cabless booster B unit PB models were built. While externally the PB models were slightly shorter than the PA model, they shared many of the same characteristics, both aesthetically and mechanically. However, they were not as reliable as EMD E-units.
Progress Rail Locomotives, doing business as Electro-Motive Diesel (EMD), is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail.
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 ALCO boxcabs were diesel-electric switcher locomotives, otherwise known as AGEIR boxcabs as a contraction of the names of the builders. Produced by a partnership of three companies, ALCO built the chassis and running gear, General Electric the generator, motors and controls, and Ingersoll Rand the diesel engine. The principle of operation was the same as modern locomotives, the diesel engine driving a main generator of 600 volts DC with four traction motors, one per axle.
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 DL-202-2 and DL-203-2 diesel-electric locomotive was an experimental freight locomotive produced by ALCO of Schenectady, New York. The primary diesel builders Alco, Baldwin and EMD pushed the War Production Board (WPB) for more opportunities to build more diesels. The Transportation Equipment Division of the WPB announced a production schedule on December 10, 1943, that allowed Alco to build one 4500 horsepower experimental diesel locomotive. This experimental diesel locomotive was to be built in the fourth quarter of 1944. The two A units were built in January 1945 and the B unit at a later date in 1945. The two A units were put on test at Building No. 37 at Schenectady to work out problems with the connecting rods and turbocharger in the Alco 241 engine, developed by both McIntosh and Seymour and ALCo. The total production run included 2 cab DL202-2 A units, and a single DL203-2 B unit. The locomotives were powered by a V12 ALCO 241 diesel engine, rated at 1,500 hp (1.1 MW). The units were released for test in September 1945. The locomotive could attain a top speed of 80 km/h (50 mph) (Freight) and 125 km/h (78 mph) (Passenger). With the B-B wheel arrangement and carbody construction, equipment layout and electrical gear these experimental units were the immediate predecessors of the FA units to come in early 1946. Outwardly, the bodies strongly resembled those on the DL-109, some of which were still under construction at Schenectady in early 1945.
The A-3080 (LS-1000) is a diesel-electric switching locomotive built between May 1949 and April 1950, by the Lima-Hamilton Corporation of Lima, Ohio, United States. The A-3080 is a 1,000 hp switcher, which became the standard for Lima's designs. By changing fuel rack settings, the A-3080 was upgraded to the A-3170, producing 1,200 horsepower from the same turbocharged Hamilton T89SA four-stroke, eight cylinder inline diesel engine, a Westinghouse generator and four Westinghouse traction motors provided the 74,508 lbf of tractive effort.
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.
Perry T. Egbert was an American engineer specializing in internal combustion engines, particularly diesel engines. Most of his career was spent at the American Locomotive Company (ALCo), America's pre-eminent manufacturer of steam and diesel locomotives for more than forty years.
The McIntosh & Seymour 531 was a diesel prime mover built by McIntosh & Seymour for use in railroad locomotives built by its parent company, the American Locomotive Company (Alco).
