Track irregularity fault commonly leads to the abnormal vibration of train which is the main cause of poor ride and even derailment. Based on Evidence Reasoning (ER) rule, this paper presents a fault identification method for determining the dynamic management levels of track irregularity using sample data measured from the accelerometers mounted in the axle-box and car-body of in-service train.
