ABSTRACT:
What follows is a description of a three track mechanism assembly for a vehicle door, and in particular for a light rail vehicle door. Each track mechanism includes a guide rail for guiding the door in its opening and closing movement relative to the vehicle body. Two of the track mechanisms include actuators for producing the opening and closing movement of the door. One of these actuators produces the desired longitudinal displacement of the door relative to the vehicle body, while the other actuator produces the desired transverse displacement of the door relative to the vehicle body. In addition, an extraction device can be included with the track mechanism having the actuator producing the desired longitudinal displacement for assisting the other actuator in producing the desired transverse displacement of the door relative to the vehicle body. The same two track mechanisms which include the noted actuators also serve to transfer the door weight to the vehicle body, each transferring a part of the door weight.
