Abstract
An apparatus to enable the automatic release of a railway vehicle hand brake system from either side of the vehicle comprises a source of fluid pressure engageable with the vehicle. A release cylinder, operable by fluid pressure, is connected to a hand brake mechanism. A valve is connected intermediate the source of fluid pressure and the release cylinder causing the release cylinder to release the hand brake system. A first valve actuator is disposed on a first side of the vehicle and is connected intermediate the valve and the source of fluid pressure. A second valve actuator is disposed on an opposed second side of the vehicle and is connected intermediate the valve and the source of fluid pressure. Both the first and second valve actuators cause the valve to initiate communication of fluid pressure from the source of fluid pressure to the release cylinder.
