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 ]
Westinghouse Air Brake Company's Rotair Valve [18] The first form of the air brake consisted of an air pump, a main reservoir (pressure vessel), and an engineer's valve on the locomotive, and of a train pipe and brake cylinder on each car. One problem with this first form of the air brake was that braking was applied to the first cars in a ...
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 ...
New York Air Brake gauges to control a Rotair Valve Westinghouse Air brake [1] Westinghouse and New York Air Brake began development of a replacement for the venerable "K Brake" in 1929. The Great Depression slowed, but did not stop, development of the new brake and, in April 1932, New York Air Brake began construction of a 200-car test track ...
When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders.
Air pump / Air compressor Westinghouse pump (US+) Powered by steam, it compresses air for operating the train air brake system. [3]: 2 The Westinghouse air brake system is used world-wide; [3]: 93 in Europe two systems that use the same principle are the Kunze-Knorr and Oerlikon systems. It can be a single-stage or, when larger capacity is ...
In March 2010, Wabtec announced that it had purchased Xorail, a railway signaling design and construction company for $40 million. [22] [23] In July 2010, Wabtec announced the plan to purchase two manufacturers of rail equipment, G&B Specialties and Bach-Simpson Corp. [24] The companies produce track products and locomotive components respectively.
[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 ...
