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, 4-6-2 represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The 4-6-2 locomotive became almost globally known as a Pacific type after a New Zealand locomotive that was shipped across the Pacific Ocean.
Under the Whyte notation for the classification of steam locomotives, 4-8-2 represents the wheel arrangement of four leading wheels, eight powered and coupled driving wheels and two trailing wheels. This type of steam locomotive is commonly known as the Mountain type, but the New York Central Railroad called their 4-8-2s the Mohawk type.
Under the Whyte notation for the classification of locomotives, 4-6-4 represents the wheel arrangement of four leading wheels, six powered and coupled driving wheels and four trailing wheels. In France where the type was first used, it is known as the Baltic while it became known as the Hudson in most of North America.
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.
Under the Whyte notation for the classification of steam locomotives, 2-10-2 represents the wheel arrangement of two leading wheels, ten powered and coupled driving wheels, and two trailing wheels. In the United States and elsewhere the 2-10-2 is known as the Santa Fe type, after the Atchison, Topeka and Santa Fe Railway that first used the type in 1903.
A 4-6-0 steam locomotive, under the Whyte notation for the classification of steam locomotives by wheel arrangement, has four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels.
Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles, and no trailing wheels. In the United States and elsewhere, this wheel arrangement is commonly known as a Consolidation, after the Lehigh and Mahanoy Railroad’s Consolidation, the name of the first 2-8-0.
Under the Whyte notation for the classification of steam locomotives, 2-8-2 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike.
Under the Whyte notation, a 2-8-4 is a steam locomotive that has two unpowered leading wheels, followed by eight coupled and powered driving wheels, and four trailing wheels. This locomotive type is most often referred to as a Berkshire, though the Chesapeake and Ohio Railway used the name Kanawha for their 2-8-4s. In Europe, this wheel arrangement was mostly seen in mainline passenger express locomotives and, in certain countries, in tank locomotives.
Locomotive classification on the Pennsylvania Railroad took several forms. Early on, steam locomotives were given single-letter classes. As the 26 letters were quickly assigned, that scheme was abandoned for a more complex system. This was used for all of the PRR's steam locomotives, and — with the exception of the final type bought — all electric locomotives also used this scheme.
The Russian locomotive class Ye, and subclasses Yea, Yek, Yel, Yef, Yem, Yemv and Yes were a series of 2-10-0 locomotives built by American builders for the Russian railways in World War I and again in World War II. They were lightweight engines with relatively low axle loadings.
The South African Railways Class 15CA 4-8-2 of 1926 was a steam locomotive.
The South African Railways Class 10D 4-6-2 of 1910 was a steam locomotive from the pre-Union era in Transvaal.
The Pashi or Pasi class locomotives were a group made up of five distinct classes of steam tender locomotives built for the Chosen Government Railway (Sentetsu) with 4-6-2 wheel arrangement. The "Pashi" name came from the American naming system for steam locomotives, under which locomotives with 4-6-2 wheel arrangement were called "Pacific".
The China Railways SL11 class steam locomotive was a class of 4-6-2 passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway and the Manchukuo National Railway by ALCO of the United States in 1908, and have the distinction of being part of the first group of standard gauge locomotives to operate in northeastern China.
The China Railways TH10 class steam locomotive was a class of 4-6-0 passenger steam locomotives operated by the China Railway. Originally amongst the first locomotives ordered by the South Manchuria Railway (Mantetsu), they were later operated by the privately owned Jichang Jidun Railway and its successor, the Manchukuo National Railway, which designated them Tehoni class. The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten-Wheeler".
The China Railways JF1 class steam locomotive was a class of 2-8-2 steam locomotives for freight trains operated by the China Railway. They were originally built in the United States, Japan and Manchukuo between 1918 and 1945 for the South Manchuria Railway (Mantetsu), the Manchukuo National Railway, the North China Transportation Company, and the Central China Railway. After the end of the Pacific War, they were taken over by the China Railway, the Korean State Railway in North Korea and by the Korean National Railroad in South Korea, and more were built in China after 1949 for the China Railway, which ultimately operated over 2,000 of the type.
The Tehoko-class (テホコ) locomotives were a class of steam tender locomotives of the Chosen Government Railway (Sentetsu) with 4-6-0 wheel arrangement. The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten Wheeler".
The Manila Railroad 200 class were 2-10-2 Santa Fe steam locomotives operated by the Manila Railroad Company (MRR), predecessor of the Philippine National Railways. They were built alongside the 4-8-2 Mountain-type 170 class by the American Locomotive Company at its Brooks facility between 1921 and 1922. During its service at the MRR, it carried heavy freight trains on the South Main Line between Manila and the Bicol Region.
