Abstract
To improve railroad safety, many researches about derailment have been tried from several aspects. The researches on derailment are mainly classified into three fields. The first is on derailment mechanism. The second is investigations on safety assessment of derailment. The last is derailment detection. To realize derailment detection systems, measurement systems and detectable algorithms have been developed. Previously, the concept of a flange-climb derailment detection system was explained and its effectiveness was examined by a 1/10-scaled vehicle and an actual bogie experiment. However, the current system has insufficient time to prevent derailment. In this paper, improved derailment detection system with prediction is proposed and its effectiveness is shown.
