Locomotives of different types (Whyte and UIC wheel notation) In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. [1] Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted ...
Whyte notation. The Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, [2] and came into use in the early twentieth century following a December 1900 editorial in American Engineer and Railroad Journal.
4-2-0. Under the Whyte notation for the classification of steam locomotives, 4-2-0 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle and no trailing wheels. This type of locomotive is often called a Jervis type, the name of the original designer.
The second 4-8-0 locomotive to appear in France was the famous 240P class of the Société Nationale des Chemins de Fer Français , with "240" in this instance referring to the French classification of wheel arrangement according to the number and arrangement of axles rather than wheels. Technically, these locomotives were developments of some ...
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.
Small firebox. 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 ...
Union Pacific 844, the only steam locomotive never retired by a North American Class I railroad. The 4-8-4 wheel arrangement was a progression from the 4-8-2 Mountain type and, like the 2-8-4 Berkshire and 4-6-4 Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which ...
Between 1931 and 1936 they were rebuilt with a 4-6-2T wheel layout and re-classified as A8. [4] The H Class locomotives built for the Metropolitan Railway in the 1920s are an example of both these factors leading to a rare use of the 4-4-4 arrangement. 242.001 at the Hungarian Railway Museum
