A method of controlling operation of a train (T) for passage of the train through a tunnel. The train has a plurality of locomotives (L1-Ln) pulling the train. The position of the lead locomotive relative to the tunnel entrance is determined, as is the amount of time before the train enters the tunnel. Each locomotive is separately configured for passage through the tunnel as a function of performance characteristics of the locomotive and the locomotive's current operating status, as the train approaches the tunnel. Once the train enters the tunnel, the performance characteristics of each locomotive are continually monitored. The performance requirements for one or more of the locomotives are then dynamically changed as a function of conditions within the tunnel and the current performance characteristics of each locomotive. This is done to maintain a sufficient combined performance capability from the locomotives to move the train through the tunnel. Upon exiting the tunnel, the locomotives' full operating capabilities are quickly restored by enhancing their thermal recoveries.
L'invention concerne un procédé de contrôle de circulation de train (T) sous tunnel, comportant plusieurs locomotives (L1-Ln) de traction. La locomotive de tête par rapport à l'entrée du tunnel est déterminée, comme l'est la durée précédant l'entrée sous tunnel. Chaque locomotive a une configuration distincte de passage dans le tunnel, selon les caractéristiques de performance de la locomotive et l'état de fonctionnement momentané, à mesure que le train s'approche du tunnel. Une fois sous tunnel, chaque locomotive voit ses caractéristiques de performance surveillées en continu. Ensuite, on modifie de façon dynamique les besoins de performance pour une ou plusieurs locomotives, selon les conditions propres au tunnel et les caractéristiques de performance de chaque locomotive. Il s'agit de maintenir une capacité de performance combinée suffisante pour l'ensemble des locomotives, permettant le déplacement du train dans le tunnel. A la sortie du tunnel, on rétablit rapidement le potentiel de fonctionnement complet des locomotives en renforçant la récupération thermique propre à chaque locomotive.
