Abstract: A railway vehicle brake system includes at least two relay valves in electrical communication with one another and in fluid communication with a brake pipe, at least two friction brake units in fluid communication with each relay valve, and at least one electric brake unit in electrical communication with each relay valve. Upon a failure of one of the electric brake units, the relay valve in communication with the failed electric brake unit sends a signal to at least one other relay valve to provide pressurized fluid to the at least two friction brake units in fluid communication with the at least one other relay valve. The at least two relay valves may include integrated electric relay valves. The at least two friction brake units may include disc brake units. Each relay valve may be positioned between and in fluid communication with the brake pipe and a main reservoir pipe.

Abstract: A system for converting an ABDW-type control valve to an ABDX-type control valve for use in a braking mechanism for a railway vehicle includes an ABDW-type control valve body in communication with an air supply system of the braking mechanism for controlling an application and release of brakes in response to changes in air pressure within the braking mechanism. A breather plate is mounted on an accelerated application valve interface on the control valve body. The breather plate has an internal stability volume for compensating a function of an accelerated application valve. A modified slide valve bushing is mounted inside the control valve body for establishing fluid communication with at least one passageway within the control valve body. At least one plug mounted is to at least one air passageway within the control valve body for sealing or choking the at least one air passageway.
