A variant, the automatic vacuum brake system, became almost universal in British train equipment and in those countries influenced by British practice. Overview of Vacuum brake : Overview of Vacuum brake It was an alternative to the air brake, known as the vacuum brake. Like the air brake, the vacuum brake system is controlled through a brake pipe connecting a brake valve in the driver's cab with braking equipment on every vehicle. Parts of the Vacuum Brake System : Parts of the Vacuum Brake System This diagram shows the principal parts of the vacuum brake system Parts of the Vacuum Brake System : Parts of the Vacuum Brake System Driver's Brake Valve- The means by which the driver controls the brake. Exhauster- A two-speed rotary machine fitted to a train to evacuate the atmospheric pressure Brake Pipe- The vacuum-carrying pipe running the length of the train Dummy Coupling- At the ends of each vehicle Coupled Hoses- The brake pipe is carried between adjacent vehicles through flexible hoses Parts of the Vacuum Brake System : Parts of the Vacuum Brake System Brake Cylinder - The movement of the piston contained inside the cylinder operates the brakes through links called "rigging“ Vacuum Reservoir -difference in pressure between one side of the brake cylinder piston and the other. Brake Block - made of cast iron or some composition material Brake Rigging - the movement of the brake cylinder piston transmits pressure to the brake blocks on each wheel Ball Valve -needed to ensure that the vacuum in the vacuum reservoir is maintained at the required level How the automatic vacuum brake works : How the automatic vacuum brake works Vacuum brake cylinder in running position: the vacuum is the same above and below the piston How the automatic vacuum brake works : How the automatic vacuum brake works Air at atmospheric pressure from the train pipe is admitted below the piston, which is forced up Present-day use of vacuum brakes : Present-day use of vacuum brakes Today's largest operators of trains equipped with vacuum brakes are the Railways of India and Spoornet (South Africa), however there are also trains with air brakes and dual brakes in use.
