ABSTRACT:
An apparatus for opening and closing ejecting doors on railway and tramway vehicles includes a motion transmission and ejection control assembly and a wing translation, drive and support assembly. The motion transmission and ejection control assembly functions to guide and forcibly shift the doors between their open and closed positions. Upon disablement of the motion transmission and ejection control assembly or an emergency, the wing translation, drive and support assembly permits the doors to be shifted to a partially open position wherein the doors can be manually opened.
