Abstract
A portal system for a railway or other vehicle having steps from the interior flooring downwards to the ground has a bridge platform to be deployed for use when the vehicle is stopped at a railway station platform. A threshold member closes at least part of the gap that typically lies between the bridge platform and the railway station platform. A carrier mechanism supports the threshold member on the outer side of the door and deploys the threshold member adjacent to the bridge platform when the bridge platform is also deployed and the door is open, and not otherwise. The carrier mechanism comprises a rail mounted on the threshold mechanism, and at least two slides mounted on the outer side of the do or and that slide with respect to the rail as the door slides between open and shut positions.
