The patent relates to a motion sensor combined with a journal bearing thermal detector which produces an output signal used to activate a train's brake system upon detection of a local wheel derailment or excessive bearing temperatures. Wheel impact with the roadbed and/or bearing temperatures exceeding a predetermined value causes the sensor to activate a percussion-initiated power source. The output signal triggers an electroexplosive brake venting mechanism, puncturing and venting the brake line for a full service brake application to stop the train.
