A door system for a railway car which provides for both high and low level access. The door system comprises a sliding door, a platform displaceable between raised and lowered positions for respectively clearing and covering the stairwell of the railway car, and a threshold extending laterally outwardly of the sliding door to provide a continuation of the platform when displaced to its lowered position. The threshold is releasably connected to the sliding door for co-linear movement with the sliding door when the platform is raised, while remaining stationary in a functional position when the platform is lowered for enabling high level boarding.

Un système de porte qui fournit à la fois un accès à l'étage inférieur et à l'étage supérieur. Le système comprend une porte coulissante, une plateforme déplaçable entre une position élevée et une position abaissée pour respectivement dégager ou couvrir le puits d'escalier du wagon, et un seuil pouvant s'étendre latéralement vers l'extérieur de la porte coulissante afin de prolonger la plateforme quand celle-ci est déplacée en position abaissée. Le seuil est connecté à la porte coulissante et se libère pour se mouvoir colinéairement avec celle-ci quand la plateforme est élevée, tandis qu'il reste en position stationnaire et fonctionnelle quand la plateforme est abaissée pour permettre un embarquement à l'étage supérieur.
