Abstract

This invention relates to a control system for controlling rotation or roll about a longitudinal axis of a variable trim railway vehicle body, so as to compensate for lateral acceleration as the vehicle moves over a curved track. A gyroscope records tilt of an axle about a longitudinal axis of the vehicle and the gyroscope signal, after integration, is passed through a threshold device to a gate or switch to open the latter at a predetermined threshold level and thereby cause a rate signal, derived from a tachometer on the vehicle, to be transmitted to a servomechanism for rotating the vehicle body.
