Abstract
A tracked transportation system uses an automatic car door opening and closing system. The car door or one panel of a two-panel door carries a lever on which is a rear abutment member designed to roll along an outside surface at the bottom of the car. This member enters a housing when the door is closed. The door is closed by holding it as the car moves slowly along a platform, by means of a hook attached to the lever.
