Abstract: In long freight trains, if a wagon far from the locomotive derails, detection of the derailment may be delayed, potentially allowing the train to continue running with the derailed wagon. We investigated a derailment detection method using mechanical contact sensors to enable early detection of wagon derailments. In this study, the installation position of the contact sensors was selected based on results from past derailment investigations and simulation results. Derailment detection tests were then conducted derailing a bogie equipped with contact sensors on an actual track. These tests confirmed that the contact sensors can detect derailment immediately after it occurs.
