FIELD: machine building.
SUBSTANCE: group of inventions relates to the railway transport. Brake system is made with first emergency brake distribution valve device, kinematically connected to first brake pneumatic cylinder of first flow path emergency brake for compressed air, controlled by first distributing valve emergency device, with emergency line and with first switching valve device, pneumatic under control of which is connected to an emergency line. In emergency line in braking system operating mode there is no pressure, and in emergency mode of braking system pressure is supplied to emergency line so that in operating mode first switching valve device is retained in first position, and in emergency mode – in second position. First switching valve device is made so that in its first position to open the emergency brake flow path and close the first emergency flow path for compressed air controlled by the distribution valve device, and in second position to close emergency brake flow path and open first emergency flow track.
EFFECT: enabling improvement of system operation in emergency mode.
