The railway freight car brake control utilizes sequential pressurization of the brake cylinder from a first auxiliary reservoir and a second auxiliary reservoir during emergency. Embodiments utilize a first supply reservoir larger in volume than a second supply reservoir. The first supply reservoir is used during a service braking mode. The larger first supply reservoir provides improved braking in a service mode, while the sequential utilization of both reservoirs provides an improved level of emergency braking available during a loaded freight car condition.
Commande de frein de wagon à marchandises utilisant la pressurisation séquentielle du cylindre de frein à partir d'un premier réservoir auxiliaire et d'un deuxième réservoir auxiliaire lors d'une urgence. Des versions de la présente invention utilisent un premier réservoir d'appoint d'un volume supérieur à celui du deuxième réservoir d'appoint. Le premier réservoir d'appoint sert pendant le mode de serrage normal des freins. Le premier réservoir plus grand rend possible un freinage amélioré lors du serrage normal des freins, alors que l'utilisation séquentielle des deux réservoirs offre un niveau amélioré du freinage d'urgence disponible lorsque le wagon à marchandises est chargé.
