OVERHEATED JOURNAL BEARING DERAILMENT PREVENTION SYSTEM
The patent application relates to an anti-derailment system to prevent train derailment due to axle failure resulting from journal bearing overheating. It includes a thermal sensor to continuously monitor the temperature of the bearing and to activate the brake system when the temperature exceeds a predetermined level. A thermally-responsive element located in the journal bearing adapter physically deforms to activate a power source. The resulting signal initiates an electro-explosive brake line venting mechanism, puncturing and venting the brake line to stop the train. Several configurations of the thermal sensor and the power source are possible.
