Rail Grinding Effect

The rails are polished before the high-speed rail is opened to traffic. This polishing strategy is called pre-polishing. Not only high-speed rails, but generally after the completion of the new line, the rails need to be polished before operation.

A design methodology for wheel and rail profiles for use .

Abstract The geometry of the interface between steel wheels and steel rails can create conditions which affect the dynamics of a vehicle, the development of rail and wheel corrugation and noise. It has come to be expected that the worn profile of the wheel is uncontrollable and must be regularly corrected. This reflects the normal experience with non-steered trucks. Dynamicists have usually ...
