A combination of existing computer sound recognition technology, listening devices and railway communication appliances that, when combined with the sound or vibration transmission properties of a railway's rail, will aid in the immediate detection and location of rockslides, washouts, railway rolling stock anomalies, like shelled or flatspotted wheels or derailed cars. It would also detect when rolling stock unintentionally started to move instead of the delay associated with waiting for it to pass the next rail electrical sensor or insulated joint. The railway communication system would then be used to aid in stopping a train short of any suspected hazard.
Combinaison de techniques informatiques de reconnaissance sonore, de dispositifs d'écoute et d'appareils de communication de chemins de fer utilisant les propriétés de transmission de sons ou de vibrations des rails d'un chemin de fer afin de faciliter la détection et le repérage immédiats de glissements rocheux, d'emportements par les eaux, d'anomalies du matériel roulant du chemin de fer, p. ex. avaries des roues (plat ou table écaillée) ou wagons déraillés. En outre, l'invention permettrait de détecter les cas où du matériel roulant se met en mouvement accidentellement, au lieu d'attendre le temps nécessaire pour passer le passage au prochain capteur électrique ou joint isolant des rails. Le système de communication de chemin de fer aiderait alors à stopper un train en cas de danger.
