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.
Under the Whyte notation for the classification of steam locomotives, 4-8-4 represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern.
Under the Whyte notation for the classification of steam locomotives, 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States, although this name was sometimes applied to locomotives of 0-10-0 "Ten-Coupled" arrangement, particularly in the United Kingdom. Notable German locomotives of this type include the war locomotives of Class 52.
Milwaukee Road 261 is a class "S3" 4-8-4 "Northern" type steam locomotive built by the American Locomotive Company (ALCO) in Schenectady, New York in July 1944 for the Milwaukee Road.
The Little Joe is a type of railroad electric locomotive built by General Electric. The locomotives had twelve axles, eight of them powered, in a 2-D+D-2 arrangement. They were originally intended to be exported to the Soviet Union and designed to operate on Soviet Railways (SZhD) 3,300-volt DC overhead line system. They were never exported to the Soviet Union due to rising political tensions. Only 20 were built, with 15 sold to domestic operators and five exported to Brazil.
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.
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a 2-6-6-2 is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and one pair of trailing wheels. The wheel arrangement was principally used on Mallet-type articulated locomotives, although some tank locomotive examples were also built. A Garratt locomotive or Golwé locomotive with the same wheel arrangement is designated 2-6-0+0-6-2 since both engine units are pivoting.
The Union Pacific Railroad 9000 Class was a class of 88 steam locomotives, built by ALCO for the Union Pacific between 1926 and 1930.
The Union Pacific Challengers are a type of simple articulated 4-6-6-4 steam locomotive built by American Locomotive Company (ALCO) from 1936 to 1944 and operated by the Union Pacific Railroad until the late 1950s.
The Milwaukee Road's class EP-3 comprised ten electric locomotives built in 1919 by Baldwin and Westinghouse. They were nicknamed Quills because of their use of a quill drive. Although they were good haulers and well liked by engineers, poor design and constant mechanical problems plagued them for their entire lives and they were among the first of the Milwaukee Road's electric locomotives to be retired.
The Milwaukee Road Class "A" was a class of high-speed, streamlined 4-4-2 "Atlantic" type steam locomotives built by the American Locomotive Company (ALCO) from 1935 to 1937 to haul the Milwaukee Road's Hiawatha express passenger trains. Numbered from No. 1 to No. 4, they were among the last Atlantic type locomotives built in the United States, and certainly the largest and most powerful. The class were the first locomotives in the world built for daily operation at over 100 mph (160 km/h), and the first class built completely streamlined, bearing their casings their entire lives. Although partially supplanted by the larger class "F7" Hudsons from 1937, they remained in top-flight service until the end. Locomotive No. 3 was taken out of service in 1949 and cannibalized for spare parts to keep the other three running until 1951.
The USRA 0-6-0 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light switcher locomotive of the USRA types, and was of 0-6-0 wheel arrangement in the Whyte notation, or "C" in UIC classification.
The Milwaukee Road class L2 were 2-8-2 or "Mikado"-type steam locomotives built by or for the Chicago, Milwaukee, St. Paul and Pacific Railroad in the period 1912–1923.
The USRA 2-8-8-2 was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-8-2 wheel arrangement in the Whyte notation, or (1'D)'D1' in UIC classification. A total of 106 locomotives were built to this plan for the USRA; postwar, it became a de facto standard design.
Canadian National class N-4 steam locomotives were of 2-8-0 wheel arrangement in the Whyte notation, or 1′D in UIC classification. These locomotives were built for the Grand Trunk Railway (GT) from 1906 until GT began purchasing class M freight locomotives in 1913. Initially classed D2 by the Grand Trunk, they were built as Richmond compound locomotives with 210 lbf/in2 (1.4 MPa) boilers feeding 22+1⁄2 inches (572 mm) and 35 inches (889 mm) by 32 inches (813 mm) cylinders.
The USRA Light Mountain was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration, the nationalized railroad system in the United States during World War I. This was the standard light freight locomotive of the USRA types, and was of 4-8-2 wheel arrangement in the Whyte notation, or 2′D1′ in UIC classification.
The Chicago and North Western Railway class J was a class of 310 American 2-8-2 locomotives. They were built between 1913 and 1923 by the American Locomotive Company. In addition, the Chicago, St. Paul, Minneapolis and Omaha Railway acquired 32, and also classified them as class J.
The Chicago and North Western Railway D Class was a class of 92 American 4-4-2 "Atlantic" locomotives. They were built by Schenectady Locomotive Works and by its corporate successor the American Locomotive Company between 1900 and 1908. In addition, the Chicago, St. Paul, Minneapolis and Omaha Railway bought seven, classifying them as class G-3
The Delaware & Hudson K-62 Class was a class of fifteen 4-8-4 steam locomotives built by the American Locomotive Company's Schenectady Works in 1943. They were intended as dual-service locomotives, hauling both freight and passenger trains until dieselization in 1953.
