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

A brake control unit for a railway vehicle having first and second cores. The first core is responsible for brake control functions and the second core is responsible for communications. A switch controls communication between the second core and a communication bus on the railway vehicle to safeguard the braking function of the first core. The second core only has write access to the communication bus when enabled by the first core, which first core determines whether the system is in a defined safe state to safeguard the braking function. This reduces the testing requirements for new communications software.

Braking system

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

An apparatus and method for controlling the operation of a screen door system. The apparatus includes a first transceiver adapted to be mounted on a train, a second transceiver adapted to be mounted on either a train platform or a portion of the platform screen door system. The first and second transceivers are configured to communicate with each other such that when a train is stopped at the train platform within a predetermined distance of and adjacent to a door of the platform screen door system, a signal is transmitted from the first transceiver to the second transceiver to open the door. When passenger embarkation and debarkation is complete, a signal is transmitted from the first transceiver to the second transceiver to close the door, and when the door is closed and locked, a signal is transmitted to the train to depart.
