Abstract: A junction for neighboring car bodies of a track-bound vehicle has a first door guided within a first end wall of a first car body for closing a doorway of the first car body and a second door guided with an adjacent second end wall of the neighboring car body for closing a doorway in the neighboring car body. The first and the second end walls are spaced apart and delimit a space therebetween. The first and the second doors are guided at the first and the second end walls so as to be movable in opposite directions. At least one coupling element for coupling the first and the second doors extends through the first and the second end walls and the space therebetween. The first and the second doors have a substantially identical construction and substantially identical moving characteristics. The coupling element is preferably a cable and a sleeve enclosing the cable.
