A brake system for a railway vehicle comprises a service brake with control valves and an emergency brake with a emergency brake valve adapted to permit or prevent emergency brake pressure from reaching the service brake control valves. The emergency brake is actuatable by a signal on an emergency brake wire. The brake system further comprises an isolating circuit adapted to permit or prevent control of the service brake control valves.

Emergency braking

In a brake system for a railway vehicle, actuation of the respective inlet, (), exhaust () and a link valve () is controlled by an electronic control unit (). The electronic control unit () has a counter for counting the number of valve operations performed by each respective inlet () and exhaust () valve, wherein the electronic control unit (), in use, determines which of the respective inlet () and exhaust () valves are to be actuated to brake the railway vehicle. The determination is made at least in part in dependence on the number of valve operations performed by the respective inlet () and exhaust () valves.

Railway vehicle brake control system

Apparatus for controlling a pneumatic brake system that includes an electronic control device to limit the maximum brake effort even when an external electrical power supply to the braking system is not present.
