Where electrified Monorail track runs through doorways, this track permits automatic or manual closing of doors with provision for return of track section when door is re-opened. Operation is extremely simple since, when the door strikes the lever arm releasing latch pin, the 6-inch swinging section turns on a hinge permitting door to close. When door is re-opened, the spring pulls the open section back into position where it is again latched to connecting track.
