Abnormal wera of tread is a commonly seen problem in the operation of metro systems. It was found that abnormal wear of tread widely exists on vehicles in a line of Beijing metro. The two main types of abnormal wear are “w” shape wear and narrow grooves on tread. It was found that hardness of the tread is strongly correlated with abnormal wear. Monitoring was conducted to watch the growth of abnormal wear on tread surface. Monitoring results show that abnormal wear of tread disappeared after changing brake shoes. Analysis showed that hardness of brake shoes have a great effect on tread wear. The competition between the wear of wheel tread caused by brake shoes and rail head was discussed to explain the reason of commonly seen abnormal wear of tread in metro systems.
