Multi-level folding step for track-bound vehicles

A folding staircase for track-bound vehicles, comprising:

• a base ladder part movably carried in the vehicle for movement between a stowed position and an extended position whereat it extends from the vehicle generally in the direction of travel;
• first displacing means for displacing said base ladder portion from said stowed position to said extended position;
• a swinging ladder part hingedly carried by said base ladder part for rotation, about a line generally transverse to the travel direction, between a first position, whereat it overlies said base ladder part, and a second position, whereat it extends from the distal end of said base ladder part to the track;
• said swinging ladder part having a first stair-like surface, exposed when said swinging ladder part is in said first position and a second stair-like surface, exposed when said swinging ladder is in said second position;
• and
• second displacing means, operatively connecting said base ladder part and said swinging ladder part, for displacing the latter from said first position to said second position.
