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.
Wheel arrangement. 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.
Steam locomotive components. Main components found on a typical steam locomotive include: enlarge. The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types.
A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks. The wheel acts as a rolling component, typically press fitted onto an axle and mounted directly on a railway carriage or locomotive , or indirectly on a bogie (in the UK), also called a truck (in North America).
A Bettendorf -style truck with axle boxes, which are not part of the side frames, at the wheels. A Swiss axlebox. Japanese archbar truck with axleboxes at the wheels. Diamond frame bogie, elliptical springs and American style journal boxes. Closeup of a shared bogie with 4 specially adapted side bearings and an articulated connector between two ...
The Mecanum wheel is a form of tireless wheel, with a series of rubberized external rollers obliquely attached to the whole circumference of its rim. These rollers typically each have an axis of rotation at 45° to the wheel plane and at 45° to the axle line. [3] Each Mecanum wheel is an independent non-steering drive wheel with its own ...
Also, the total number of blades of all of the propellers combined represents the height of Colorado's tallest fourteener, Mount Elbert, which is 14,440 ft (4.40 km) tall. Contrary to common belief, the propellers do not generate any electricity for the trains or any part of the airport, and are strictly decorative. [19]
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.
