The assessment of the technical condition of the locomotive-wagon-track system is the main task of the safety of rolling stock movement, especially in curves and mountain-pass sections. During the movement of the train, loads are applied, which are distributed in accordance with the technical condition of the elements of this system. The safety of rolling stock is evaluated not only by the state of the system, but also in separate classes, which initially assess the risk of deviations in each class separately. The development of a methodology for determining the causes of convergences makes it possible to determine the share of participation of each class in the convergence of rolling stock. This methodology is based on the analysis of specific convergences in each class "locomotive", "wagon" and "track" and is based on a quantitative and qualitative analysis of the controlled parameters of each class. The data is obtained using specialized car laboratories and equipment that records deviations in this class separately. After processing the data, a comparison is made with the standard parameters and, accordingly, the degree of danger to the movement of rolling stock is determined. The most dangerous deviations are ranked by degrees and technical parameters in each class of the system. The application of this technique allows to identify dangerous factors based on their ranking and assessment of the risk of derailment of rolling stock. The risk of derailment of rolling stock is assessed both in one class and in combination with deviations of another class. Special attention is paid to mountain-pass sections, which increase the risk of derailment in case of deviations in certain classes of the locomotive-wagon-track system.
