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 ...
Railway brake. A traditional clasp brake: the cast iron brake shoe (brown) is pushed against the running surface (tyre) of the wheel (red), and is operated by the levers (grey) on the left. A band brake fitted to an 1873 steam locomotive of the Rigi Railways. A railway brake is a type of brake used on the cars of railway trains to enable ...
Traditional train braking systems use pneumatic valves to control and generate brake applications on the cars along the length of the train. In general, this conventional system consists of a brake pipe that runs the length of the train which supplies air to reservoirs mounted on each of the cars. When the brake pipe and car components are ...
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed "rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and "regenerative" if the power is returned to the supply line.
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s. A variant, the automatic vacuum brake system, became almost universal in British train equipment and in countries influenced by British practice. Vacuum brakes also enjoyed a brief period of adoption in the United States, primarily on narrow-gauge railroads ...
The electro-pneumatic brake system on British mainline railway trains was introduced in 1950 and remains the primary braking system for multiple units in service today, although London Transport underground trains had been fitted with EP brakes since the 1920s. The Southern Region of British Railways operated a self-contained fleet of electric ...
A linear eddy current brake in a German ICE 3 high-speed train in action. An eddy current brake, also known as an induction brake, Faraday brake, electric brake or electric retarder, is a device used to slow or stop a moving object by generating eddy currents and thus dissipating its kinetic energy as heat.
Driver's brake handle in a class 317 electric multiple unit. On trains, the expression emergency brake has several meanings: . The maximum brake force available to the engine driver from the conventional braking system, usually operated by taking the brake handle to its furthest position, through a gate mechanism, or by pushing a separate plunger in the cab.
