  • Patent number: 6550831
    Abstract: A lock and emergency release system for a door normally power operated by a door operator. The system comprises a lock displaceable between an idle position to a functional position in which opening of the door by the door operator is prevented. An emergency release handle is manually operable for simultaneously displacing the lock to its idle position and releasing the door from the door operator, thereby allowing the door to be manually opened.

  • Patent number: 6443072
    Abstract: 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.
