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 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).
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
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.
The primary reason that the original RoadRailer concept was not viable was the weight penalty imposed on the trailers because of the attached railroad wheelset. This was resolved in later designs which removed the integrated wheelset by having a dedicated rail bogie assembly that stayed in the rail yard, as seen today. [citation needed] [9]
Although this is mostly a scratch-builders scale, there is an increasing supply of kits, parts and figures. Some modelers using 7 ⁄ 8 scale operate on 32 mm (1.26 in) track, used to replicate 18 in (457 mm) gauge industrial lines found in Great Britain and other countries. Live steam: 1:16: 89 mm Ridable, outdoor gauge.
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).
With the permission of the Royal Railway Administration in Frankfurt a. M., wheelsets with paper discs were manufactured in the main railway workshop in Saarbrücken and in the railway car wheels factory of the van der Zypen brothers in Deutz and then put into use. Such wheelsets with paper pulp discs were in regular service on wagons for a ...
