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 notations varying by country.
A rail vehicle wheelset, comprising two wheels mounted rigidly on an axle A wheelset is a pair of railroad vehicle wheels mounted rigidly on an axle allowing both wheels to rotate together. Wheelsets are often mounted in a bogie (" truck " in North America ) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle.
A selection of early 20th century locomotive types according to their Whyte notation and their comparative size Whyte notation from a handbook for railroad industry workers published in 1906 [1] The Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel ...
The UIC classification of locomotive axle arrangements, sometimes known as the German classification [1] or German system, [2] [3] describes the wheel arrangement of locomotives, multiple units and trams.

The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads.Essentially a simplification of the European UIC classification, it is widely used in North America to describe diesel and electric locomotives (including third-rail electric locomotives).
The small rail wheels fitted to road–rail vehicles allow them to be stowed away when the vehicle is in road-going mode. Wheels used for road–rail vehicles are normally smaller than those found on other types of rolling stock, such as locomotives or carriages, because the wheel has to be stowed clear of the ground when the vehicle is in road-going mode.
This has complicated maintenance of the system, as it requires custom wheelsets, brake systems, and track maintenance vehicles. [5] The New Orleans, Opelousas and Great Western Railroad (NOO&GW) used 1,676 mm (5 ft 6 in) broad gauge until 1872, and the Texas and New Orleans Railroad used 1,676 mm (5 ft 6 in) broad gauge ("Texas gauge") until 1876.
