There are several indexes to evaluate running safety of railway bogie. Some of then are derailment coefficient and wheel-load decreasing rate, which must be measured by special wheelset named PQ wheelset. However preparing this PQ wheelset and measuring these indexes by using PQ wheelset are very expensive and difficult, so simplified methods to measure and evaluate these indexes must be desired without using PQ wheelset. In this study. several methods to evaluate these safety indexes by measuring equipped sensors on the bogie frame are discussed, and especially methods of measuring vertical force between wheel and rail are reported.
