Title (EN) AUTOMATIC BAIL OFF FOR LOCOMOTIVE BRAKING SYSTEM
(FR) AFFRANCHISSEMENT AUTOMATIQUE POUR SYSTÈME DE FREINAGE DE LOCOMOTIVE
Abstract:
(EN) A system for automatically performing a bail off of the locomotive brakes in response to certain train braking operations without the need for the train operator to manually bail off the locomotive brakes. The system includes a controller that is programmed to determine when an appropriate train braking operation has been requested and to issue commands to the locomotive braking system to cause the locomotive brake cylinder to be reduced to zero pressure or a predetermined minimum pressure. The controller is also programmed to determine when an automatic bail off should be inhibited and/or cancelled depending on ongoing train conditions.
(FR) L'invention concerne un système pour réaliser automatiquement un affranchissement des freins de locomotive en réponse à certaines opérations de freinage de train, sans que l'opérateur de train n'ait besoin d'affranchir manuellement les freins de locomotive. Le système comprend une unité de commande qui est programmée pour déterminer lorsqu'une opération de freinage de train appropriée a été demandée, et transmettre des instructions au système de freinage de locomotive pour amener le cylindre de frein de locomotive à être réduit à une pression nulle ou une pression minimale prédéterminée. L'unité de commande est également programmée pour déterminer lorsqu'un affranchissement automatique doit être inhibé et/ou annulé en fonction de conditions de train en cours.
