Reducing wear on the ridges of rolling stock wheel sets is one of the most important tasks of railway transport. This task is complex and requires consideration as a single "locomotive-wagon-way" system. The wheel–rail interaction depends on the nature of the application of the longitudinal force of the locomotive, especially in curved sections of the track. For example, we can say that for the mountainous terrain of the VSZHD, on specific sections of the track, the "life of the rail" is no more than 2-3 months, followed by its replacement.

Statistics of car detachments based on wear of ridges and side rail wear indicate an increase in the number of failures related not only to wheel pairs, but also to the condition of the track. With an increase in the volume of goods transported and an increase in the speed of trains, the state of the track also changes. As a result, the intensity of operation of the rolling stock increases, and the wear of parts and components of the car increases. During the period of increasing wear intensity of the wheel ridges, the design of the freight car has not undergone fundamental changes that could cause an increase in the intensity of wear of the wheel ridges. However, it was found that the wear rate of the ridges of the wheels of freight cars is different for different types of cars of the same composition. About 30 % of cars have extreme wear, and the wear of the ridges depends on the technical characteristics of the wagon bogies, as well as on the body structure and technical condition of the car. This dependence has a great impact on the wear rate of the wheel ridges.
