Reduced wear of rails and wheels of rolling stock is a very important task of railway transport. The flange profile studies were conducted to determine the machining sizes for the flange of railcar wheel pairs. The studies made it possible to determine that the rejection criterion characterizing dangerous form of the flange wear is a horizontal projection forming the worn-out surface of the flange between the points located at about 2 mm below its top and 13 mm above the average taping line. There are calculations made on the wear of the wheel pairs of gondola cars of the EC70 model manufactured in China after three years of operation.
