EFFECT ON TRACK OF HEAVY AXLE LOADS

The author recalls and makes reference to numerous studies on the problems of damage to rails caused by heavy axle loads. He quotes recommendations developed by AREA with regard to permissible axle loads in relation to wheel diameter and vehicle speed, and the ultimate tensile strength of rail steels. He mentions the experience of Australian Railways operating meneral lines with block- trains made up of very heavy wagons. He then gives formulae and tables in which the track maintenace cost, as per traffic unit, is expressed in relation to various variables and parameters: speed, axle weight on rail, age of ballast, linear weight of rail, curve radius, etc.
