Abstract
An improved gap filler in the form of a single plate or a plurality of plates attached to the train car exterior or emanating from below train car vestibule floor which permits transit line system operator to utilize one device to obtain any desired gap minimization at every train car door in a trainset relative to its corresponding platform edge at all stations on its transit line regardless of platform and/or track configuration while simultaneously adhering to its gap clearance standards pertaining to safe passage of any train within its fleet through any station.
Claims30
A device to mitigate the gap existent between a train car door and a train station platform, comprising:
- a plate assembly communicating with a threshold of a train car door,
- said plate assembly providing a continuous support structure for passage between a train car door and a train station platform edge,
- said plate assembly moveable between a first state wherein at least one plate of said assembly is positioned away from said train station platform edge and a second state wherein said at least one plate is positioned toward said train station platform edge to form at least a portion of said continuous support structure and mitigate said gap,
- a controller retrieving a predetermined distance from storage and controlling said plate assembly to extend said continuous support structure from said train car by the predetermined distance in said second state, the predetermined distance being based on a width of said gap so that said plate assembly accommodates different sized gaps.
