Abstract
Derailment control system for railway vehicles that, in addition to detecting and issuing a warning of said derailment, provides control over the brake of the derailed vehicle or vehicles and provides additional emergency braking and/or a warning to the driver's cab, said system having a main unit (1) to which are joined: an inertia sensor or detector (8) designed to detect derailments, an indicator (9) or device responsible for indicating that the derailment control system has been triggered and for keeping the system activated, a stopcock (10) that deactivates the derailment control, and a bottom connection point (11) for testing that makes it possible to simulate a triggering of the system via a threaded eyebolt, facilitating verification of proper operation both during bench testing and when the system is installed on the vehicle (7), and a device (39) situated at the exhaust outlet through which the automatic brake pipe (ABP)(5) is vented when said derailment is detected.
