Abstract:
1. A derailment control system for a railway vehicle having an inertia sensor to detect derailment, which in the event of a sharp blow caused by a derailment acts on an automatic brake pipe triggering the application of a train's emergency brake, the system comprising: means for emptying a brake cylinder pipe on the vehicle when derailed to-release the brake and, thus, enabling wheels of the derailed vehicle to roll; and a device situated at the exhaust outlet through which the automatic brake pipe is vented when a derailment is detected, which provides an additional simultaneous braking on the entire train or a warning signal to a driver's cab, wherein the device comprises a device piston moved by the action of air released from the automatic brake pipe through the exhaust, which in the course of said device piston travel causes the closing or opening of a microswitch responsible for opening and closing a safety circuit.
