2. Railway air brake - Wikipedia

   en.wikipedia.org/wiki/Railway_air_brake

   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] The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's ...

   The GCOR is supplemented by System Special Instructions, Timetables, Hazardous Materials Instructions, Air Brake and Train Handling Instructions, and General Orders. These documents are issued by each individual railroad. System Special instructions, Timetables, and General Order can modify or amend the General Code of Operating Rules. GCOR 1.3 ...

4. Air brake (road vehicle) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(road_vehicle)

   Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.

   Air brake (aeronautics), a type of flight control system used on aircraft to reduce speed; On ground vehicles, (more formally, specified as) compressed-air-actuated braking systems: Air brake (road vehicle), friction-mediated type of brake used on large road vehicles in place of hydraulic brakes; Railway air brake (used on both locomotives, and ...

6. Driver's brake valve - Wikipedia

   en.wikipedia.org/wiki/Driver's_brake_valve

   The driver's brake valve is a complicated valve system for controlling the compressed air brake of a railway vehicle. [1] Depending on its setting, it controls whether the brake pipes of a compressed air brake are evacuated and thus whether braking is applied or maintained; or if the brake pipes are connected to a compressed air reservoir, it ...

7. Railway brake - Wikipedia

   en.wikipedia.org/wiki/Railway_brake

   An air brake compressor is usually capable of generating a pressure of 90 psi (620 kPa; 6.2 bar) vs only 15 psi (100 kPa; 1.0 bar) for vacuum. With a vacuum system, the maximum pressure differential is atmospheric pressure (14.7 psi or 101 kPa or 1.01 bar at sea level, less at altitude). Therefore, an air brake system can use a much smaller ...

8. New York Air Brake - Wikipedia

   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 ...

9. Westinghouse Air Brake Company - Wikipedia

   en.wikipedia.org/wiki/Westinghouse_Air_Brake_Company

   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 ...
