ABSTRACT:
Access to a rail vehicle is effected by a board that is movable between a retracted position in which it is housed beneath the top face of the floor of the vehicle and an extended position in which it constitutes an access ramp between a platform and an entrance doorsill of the vehicle. The device includes an actuator for driving the board and a stop terminating translation of the board in its extended position. The actuator is disposed in the plane of the board. The device also tilts the board after stopping the board's movement in translation so that the outside end of the board rests on the platform and so that the board co-operates with the entrance doorsill to provide a continuous surface without any offset. The entrance doorsill remains stationary.
