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 ...
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 ...
[3] Its first section makes it unlawful, among other things, for a railroad company engaged in interstate commerce to run any train without having a sufficient number of the cars so equipped with train brakes (such as air brakes) that the engineer on the locomotive can control the speed of the train without requiring brakemen to use a hand ...

The Kunze-Knorr brake (Kunze-Knorr-Bremse or KK-Bremse) is an automatic compressed-air brake for goods, passenger and express trains. It was the first graduated brake for goods trains in Europe . When it was introduced after the First World War , goods train brakes switched from hand operation to compressed-air in various European countries.
A pair of gladhand connectors between railroad cars A gladhand connector on a trailer. A gladhand connector or gladhand coupler is an interlocking hose coupling fitted to hoses supplying pressurized air from a tractor unit to air brakes on a semi-trailer, [1] or from a locomotive to railway air brakes on railroad cars. [2]
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.
