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.
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 ...
Other operators of vacuum brakes are narrow-gauge railways in Europe, the largest of which is the Rhaetian Railway. Vacuum brakes have been entirely superseded on the National Rail system in the UK (with the British Rail Class 121 "bubble cars" being the last mainline trains to have vacuum brakes-they finished service in 2017), although they ...
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.
British Railways inherited a variety of brake vans from each of the Big Four: GWR, LNER, Southern Railway and LMS due to the nationalisation of the railways in 1948. A brake van , on a train, is a wagon at the rear of a goods train where a guard would sit with a hand 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 nearest equivalent to a brake van still in use on main-line British railways is the driving van trailer (DVT), which is used on locomotive-hauled trains to control the locomotive from the other end of the train in a push-pull configuration, removing the need for the locomotive to run around its train at termini. Although the DVT has braking ...
