Abstract
Development of new management approaches on the railway, based on risk
management, with the adoption of standards EN 50126-1 and EN 50126-2 provide safety management processes for railway applications. Risk factors can be determined using different risk assessment methods like FMEA, FMECA, FTA etc. or their combination. The permissible risk values based on accepted values and defined preventive measures are designed on the current maintenance plan for freight wagons. Preventive measures are established for revision maintenance which is carried out every 4-6 years. Risk analysis of coupling system failure can be different depending on the time of analysis (regulations, exploitation conditions) and the applied maintenance practice. FMEC analysis applied to train coupling systems based on regulation shows different permissible risk values that don't match exploitation data
