FIELD: transportation.

SUBSTANCE: invention relates to railway transport, particularly, to high-speed freight and passenger cars. Braking system comprises independently operating electropneumatic air distributor and pneumatic air distributor of cargo type, connected by air ducts via disconnecting valve with brake main line, with spare reservoir and switching valve connected with brake cylinders through automatic mode. Electro-pneumatic air distributor via supply air duct, made in separate bracket, is connected through maximum pressure valve with spare reservoir according to first version and through outlet air duct made in separate bracket is connected to opposite supplying branch of switching valve. In the second version of braking system there is additionally installed a separate spare tank connected to brake line through check valve and disconnecting valve to increase reserve of compressed air and increase of brains inexhaustibility.

EFFECT: higher efficiency and reliability of braking system operation due to simplification of its design and provision of electrically-pneumatic braking.
