Intercommunication between two connected vehicle, e.g. rail vehicles, comprising a bellow and a bridge

The transition bridge (10) has a bellows (20) provided with a finger (17) adjusted in height of the transition bridge. A truss bridge is provided on lower side of the transition bridge. The truss bridge runs over a part of the transition bridge at a distance from base of the transition bridge. The finger lies on the truss bridge for supporting the bellows.
