RAILWAY VEHICLE BODY TILTING SYSTEM

A railway vehicle body tilting system has a height control valve (71) for supplying and discharging compressed air to and from an air spring by the action of an actuator, an auxiliary control valve (72) for supplying compressed air to the air spring and thereby causing a car body to tilt, a backup valve (73) for switching the connection between the air spring (53) and either the height control valve (71) or the auxiliary control valve (72), and a controller (11, 21) installed in each of a plurality of vehicles (1, 2) linked together as a train. During normal operation, the controller (11, 21) provided in each of the cars controls the height control valve (71) of the respective car and monitors for faulty operation in other associated controllers (11, 21). If a fault arises in an associated controller, control over the malfunctioning controller is terminated, and another properly functioning controller controls a backup valve in the car provided with the malfunctioning control device.
