In order to achieve effective lubrications of wheel/rail contact area, a method of detecting sharply curved tracks where wheel/rail wear may progress is desired. The present study examines the use of monitoring bogie that can collect continuous data of wheel/rail contact forces during commercial operations. Based on the idea of friction circle, a new index is proposed, which is based on the ratio of longitudinal force to lateral force acting on the leading-inside wheel of a bogie. The relationship between the new index and leading-outside wheel wear is shown using experimental data from the roller-rig tests conducted in previous studies. Multi-body dynamics simulations are carried out to investigate the relationship between the new index and wear number. Moreover, the new index is applied to data collected by the monitoring bogie during commercial operations. The roller-rig test results, the simulation results, and the data collected by the monitoring bogie suggest that the new index could be a useful index for evaluating the leading-outside wheel/rail wear.
