Articulated vehicle, e.g. articulated bus or rail vehicle

The vehicle has two articulated vehicle parts connected with each other with an outer corrugated bellow by a passage (10). The bellow includes a connecting platform (30) provided at side walls (11a) and/or a ceiling (11b) on an inner side. The connecting platform reinforces the side walls and/or the ceiling in a direction transverse to a longitudinal axis of the vehicle. The connecting platform is formed as bellow sets (60) that extend parallel to the longitudinal axis. The bellow and an inner corrugated bellow (15) are arranged at a distance to each other between the vehicle parts.
