Abstract: The passenger connecting passageway between two rail vehicles includes a respective half-passageway at the end of each vehicle. Each half-passageway has a respective main frame. To lock the half-passageways together, a locking device including at least one locking hook and preferably a pair of hooks is arranged on the outside of one vertical support of the main frame of one half-passageway. A receiving pin on the adjacent main frame of the other half-passageway receives the hook and a device swings the hook selectively on and off the pin. A swingable pull together device on the inside of the half-passageway includes a pull strap supported at the vertical support on one half-passageway that hooks on a receiver on the vertical support on the other half-passageway and a ratchet rotates an arm that winds the strap to pull the half-passageways together.

Abstract: Upon the measurement of lateral acceleration conditions on a rail vehicle and the optimizing accordingly of the inclination of the load-bearing floor, problems result due to time delays between the measurement and the setting as well as to disturbances which are included in the measurement. They are eliminated in the manner that track data relevant to lateral inclination are stored in a track modeling memory (27) together with the actual position (I) detected, the track data relevant at that time or in the future are called up and the precise floor inclination (.alpha..sub.1) necessary at the time is calculated (29) as a function of the detected instantaneous speed (9) of the vehicle and set (11).

Abstract: The inner covering for the connecting corridors between cars of rail vehicles consists in each case of side wings, each of which consists of at least two independent frames (1, 2, 3) the spars of which are pivoted to each other at the corners, the frames being held in bottom and top telescopic guide rails (4). When the outermost vertical frame spars are fastened by hinges (8) to the car body or coupling frame, the inner covering can follow all movements which occur.
