ABSTRACT:
The invention concerns an electrically assisted pneumatic train braking system. In a normal emergency/service pneumatic braking system a pneumatic pressure change must propagate along the train braking system from car to car. The present system includes two valves which are connected to each end of the brake pipe of each car, the first is responsive to a pressure change in the brake pipe to produce an electrical signal and the second being responsive to the electrical signal to produce a pressure change in the brake pipe. Thus, the propagation time for the whole braking system is reduced to little more than that for the total length of the couplings between cars.
