Study on safety assessment of flange climb derailment at low speed based on the relationship between the derailment quotient and wheel rise

In railways, on-track running tests are implemented to assess running safety against flange climb derailment.Results of tests depend on the frequency component of measured data.In this paper, the relationship between the measured data of the derailment quotient, which is the assessment quantity of derailment, and wheel rise are investigated.The dat
