The goal of the work is substantiation of using the proposed method of sliding high-current contact wear prediction by comparing the forecasting results with the experimental ones. In conditions of ensuring high quality services transportation of passengers and cargo, the issue of ensuring reliable operation of the high-current contact 'contact wire-pantograph contact element' becomes especially relevant. The reliability of the traction system as a whole depends of the high-current contact reliability. The feasibility of using the proposed method for predicting wear of sliding high-current contact is substantiated. This method differs from the existing ones due to possibility of taking into account the set of factors, which influence on current collection process, by comparison the predicted wear values of the sliding highcurrent contact with the data obtained experimentally. The results show a possibility of reducing the wear of the contact wire up to 11% in its interaction with graphite contact elements and increasing the efficiency of the use of contact elements up to 25%.
