Standard

Wheel Flange Angle for Passenger Equipment

Abstract

This standard defines the minimum flange angle and the minimum length of the surface on the flange, over which the angle must be maintained. These wheel flange parameters are important in reducing the risk of low-speed wheel climb derailments. The standard also provides drawings of wheel profiles that are compliant with the requirements of this standard.
