Performance evaluation of operating freight cars with improved technical characteristics for JSC “Russian Railways” on the testing basis

Abstract

The article describes the mechanism for evaluating the efficiency of operating freight cars with improved technical characteristics on the infrastructure of railways on the basis of complex tests. It allows determining the impact of the operation of such cars on the costs of JSC “Russian Railways”, including the costs of fuel and energy resources for traction of trains, the maintenance of the railway track, the maintenance and operation of freight locomotives and the maintenance of freight cars along the route. An important feature of the assessment is that it is based on data obtained as a result of testing in real-world conditions. Technical and economic assessment of the change in costs of JSC “Russian Railways” in the case of the operation of innovative freight cars should be used in the development of budgets in conjunction with the plans to purchase new cars, to prepare proposals for the development of tariff mechanisms that stimulate the purchase of cars with improved technical characteristics that provide additional economic benefits, associated with a decrease in the costs of the owner of the infrastructure. The purpose of such mechanisms is, on the one hand, to stimulate the renewal of rolling stock through innovative carriages, on the other hand, to improve the efficiency of rail transport. Based on JSC “VNIIZhT” assessment of the effect for JSC “Russian Railways”, the expert commission of the Federal Antimonopoly Service of the Russian Federation approved the application of the tariff scheme 25 (4) with a reduced fee for the empty run of cars for 12-2143 gondola cars produced by JSC “AltaiZavod”. According to the current price list for freight transportation, the effect of operating a number of models of innovative cars on the infrastructure of JSC “Russian Railways” is fully included in tariff preferences. However, to increase the interest of Russian Railways in the operation of innovative cars, it seems advisable to leave the owner of the infrastructure between 30 and 50% of the economic effect.
