RAIL PROFILE OPTIMIZATION

Profile Optimization in the Urban Rail Context (continued)

Overall experience has shown the benefits of obtaining consistent wear over the full width of the wheel and the rail. Controlled wear reduces re-profiling requirements and reduces hollowing of the wheel tread. The elimination of hollow wheels has been shown to extend the life cycle of switches and crossings and reduce plastic flow on the rail head.
