Rail Road Wheel Requirements and Manufacturing Processes

A railroad wheel has evolved over the last two centuries with increasing load and speed. A harder wheel maintains its geometry and therefore is able to negotiate the track without giving rise to high forces. This paper describes pressure poured cast wheel and forged wheel manufacturing processes. As experimentally verified on other railways, pressure poured cast wheels have been used satisfactorily in locomotive and passenger services in the Indian railways where conventionally forged wheels were used worldwide.
