The paper describes the methodology of approach to the procedure of performing risk assessment using the Failure Mode and Effects Analysis (FMEA), according to the latest edition of the PN-EN IEC 60812:2018 standard. The paper notes the application of the analysis for assemblies and subassemblies of rail vehicles, where it is increasingly used, according to the requirements of railway companies. An example of the application of the FMEA method is presented for the draw-and buffing gear of a coal car of normal construction. After the decomposition of the system and the determination of the functions performed by the object and the possible risks, an analysis was carried out, which showed that the values of the Risk Priority Number (RPN) for individual causes of failure do not exceed the critical value of RPN=150 according to the above-mentioned standard. As a result, taking preventive measures to reduce the risk of hazards is not necessary. Therefore, the examined system should be considered safe.
