The authors determined the intensity of the increase in wear of various elements of the body. It has been established that the lower trim, the roof slope and the lower part of the side wall have the greatest wear. It is proposed to use aluminum alloys for the modernization of passenger car bodies. The advantage of such a technical solution is an increase in the corrosion resistance of the body. The reduction of tare allows to reduce the specific resistance to train movement, reduce fuel and electricity costs for train traction. To reduce operating costs using the basic provisions of the locomotive traction theory, calculations were made to determine the energy consumption for the movement of a passenger train according to the profile conditions of the real section of the regional branch of the Southern Railway by diesel and electric locomotive traction with the base variant and the variant of passenger cars with reduced tare weight) in composition of the train. It has been established that the annual savings in energy costs for the traction of passenger trains when using passenger cars with a reduced tare weight is about 1 million UAH.
