In the device for pivotally connecting neighboring car bodies of a rail vehicle, especially for commuter traffic, each car body (1,2) is supported by a ball-and-socket joint (6) on a common swiveling railway truck (4). The swiveling railway truck (4) carries a central portal (3) between the car bodies and the central portal (3) is coupled kinematically by means of a swiveling linkage mechanism with them in the vicinity of a roof of the car bodies. The swiveling linkage mechanism includes car body arms (7) pivotally connected to the car bodies (1,2) and central portal arms (8) pivotally connected with the central portal (3) and with the car body arms (7). Both car bodies (1,2) and the central portal (3) form lower legs of two kite-shaped quadrilateral linkages and the car body arms (7) and the central portal arms (8) form the upper legs of the quadrilateral linkages. Both central portal arms (8) are guided with the help of a control device (10,11) mounted on the central portal so that they take identical angles (.alpha.) in relation to the vertical axis of the central portal (3).
