A railway air brake is a railway brake power braking system with compressed air as the operating medium. [1] Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. [ 2 ]
A railway brake is a type of brake used on the cars of railway trains to enable deceleration, control acceleration (downhill) or to keep them immobile when parked. While the basic principle is similar to that on road vehicle usage, operational features are more complex because of the need to control multiple linked carriages and to be effective ...
Also, since the brake pipe is typically used for control and supply of air to the cars, if an engineer is not careful, the air supply can be depleted. Further, since the engineer is only aware of the brake pipe pressure and flow of air into the brake pipe, it is not easy to know the state of the train brakes at any given time.
The invention of the fail-safe railway air brake provided an external means for stopping a train via a physical object opening a valve on the brake line to the atmosphere. Eventually known as train stops or trip stops , the first mechanical ATS system was installed in France in 1878 with some railroads in Russia following suit using a similar ...

Air brakes need a tap to seal the hose at the ends of the train. If these taps are incorrectly closed, a loss of brake force may occur, leading to a dangerous runaway. With vacuum brakes, the end of the hose can be plugged into a stopper which seals the hose by suction. It is much harder to block the hose pipe compared to air brakes.
