Braking System

The air brake system uses compressed air to apply the brake block (or pad) to the wheel and to control the operation of the brake along the train. The compressed air is supplied by a motor driven compressor on the locomotive or train.

The brake control is actuated from a "driver's brake valve". This valve is used to feed air to the brake pipe or to allow air to escape from the brake pipe. A fall in brake pipe air pressure causes a brake application on each vehicle whilst a restoration of pressure causes the brake to release.

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. The operation of the brake equipment on each vehicle depends on the condition of a vacuum created in the pipe by an ejector or exhauster. The ejector, using steam on a steam locomotive, or an exhauster, using electric power on other types of train, removes atmospheric pressure from the brake pipe to create the vacuum. With a full vacuum, the brake is released.
