Analysis of Wheel/Rail Contact Characteristics on a Turnout

The characteristics of geometric contact between the wheel and rail on the turnout must be precisely investigated to limit the speed of trains at a turnout. The characteristics of the contact have an effect on the derailment of trains at a turnout and maintenance of a turnout. In this paper, an analysis program for characterization of the contact on a turnout is first developed. With the developed program, the characteristics of geometric contact, including the contact during steady state running, were analyzed and discussed for improving the safety of trains.
