ABSTRACT:
In a system to prevent train derailment due to axle failure resulting from ournal bearing overheating, a thermal sensor continuously monitors the temperature of the bearing and activates the brake system when the temperature exceeds a predetermined level. A thermally-responsive element located in the journal bearing housing physically deforms to activate a power source. The resulting signal initiates an electro-explosive brake line venting mechanism, which punctures and vents brake line to stop the train. Several configurations of the thermal sensor and the power source are possible.
