Abstract
A handicapped-entrance gate for retrofitting a train-station comprises a door panel that forces itself normally closed, but can be pushed open from either side. A closing mechanism is fully contained within a cap rail along to top edge of the door and operates in either direction to close the gate slowly after it has been opened. Fixed axles enter the gate panel from above and below on the pivoting side. The closing mechanism is geared to at least one of these fixed axles to allow the gate to be opened easily and to self-close over a period of time. Springs are used in opposition to hydraulic dampers such that the springs close the gate and the dampers delay the closing.
