Abstract: A system for maintaining brake cylinder pressure includes a brake cylinder passage configured to be in fluid communication with a brake cylinder, a brake pipe passage configured to be in fluid communication with a brake pipe and a brake cylinder, a first valve member moveable between a first position and a second position, and a second valve member in fluid communication with a reference pressure. The second valve member is configured to move the first valve member from the first position to the second position based on a differential between a pressure within the brake cylinder passage and the reference pressure, where the brake pipe passage is configured to only supply air from a brake pipe to a brake cylinder when the first valve member is in the second position.

Abstract: A system for maintaining brake cylinder pressure comprises a maintaining valve, a brake pipe, an emergency reservoir, and a brake cylinder configured to be in fluid communication with the brake pipe and the emergency reservoir. The brake pipe is configured to sustain a predetermined pressure within the brake cylinder during a brake application based on a differential between a pressure of the emergency reservoir and a pressure of the brake 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.
