Abstract

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.
