Axleload

Axleload

The axleload is the weight bearing upon the track or road by a rail or road vehicle. If each axle has two wheels then the axle load is twice the load on each wheel. Since the track or road has a certain strength, axleloads should not exceed a certain tonnage lest damage be caused to that track or road.

Typical axleloads

Rail

General

For railways, the permissable axleloads is determined by weight of the rails, size and frequency of the sleepers, quantity and type of ballast, and depth of formation. On sharp curves, the frequency of sleepers often needs to be increased.

Examples

* 2008 - Fortescue Metals - 68kg/m (?) rail - 40T axleload - 80km/h

* 1888 - Sierra Leone Government Railway - 15kg/m rail - 5T axleload - 20km/h

* 1942 - Kriegslokomotive‎ - - 15T axleload - 80km/h
