In this article is dealt with the ways of improving the diagnostic accuracy of braking systems of passenger cars, taking into account the operational factors. A diagnostic system that monitors the pneumatic processes and transmits the data in real time has been implemented. The method proposed has provided an increase of reliability from 83.1% to 87.6%.

Keywords: railway transport, air distributor, automatic brakes, railcar, diagnostics, monitoring, traffic safety
