Abstract
A folding staircase for track-bound vehicles comprises a base ladder part, movably carried in the vehicle, and a swinging ladder part hingedly carried by the base ladder part. The base ladder part is movable between a stowed position and an extended position whereat it extends from the vehicle generally in the direction of travel. The swinging ladder part is rotatable between a first position, whereat it overlies the base ladder part, and a second position, whereat it extends from the distal end of the base ladder part to the track. Devices are provided for displacing the base ladder portion from the stowed position to the extended position and for displacing the swinging ladder part from the first position to the second position.
