Abstract: A connecting platform for use with the end of a railroad car, the platform cooperating with a connecting platform of another car articulated to the railroad car, both railroad cars having the usual spring-biased buffers. The connecting platform includes a platform part supported on the end of the railroad car and slidable with respect to the car in the longitudinal direction of the car, the end face of the platform part remote from the car and the end face of the buffer remote from the car being in substantially the same vertical plane perpendicular to the longitudinal direction of the car. A linkage arrangement responds to movement of the buffer toward and away from the car for moving the platform part toward and away from the end of the car so as to maintain the end faces of the buffer and platform part in substantially the same vertical plane.

Abstract: An articulated bridge as a component of a detachable gangway floor plate between two articulated interconnected railroad cars, the bridge being provided with several elongated bridge elements arranged in succession laterally, and running transverse to the direction of the bridge. The articulated extremities of the bridge are defined by the side walls of a frame approximately following the contours of the bridge. One end section of the bridge is designed for attachment to one of the two interconnected railroad cars and the other end section of the bridge is designed for attachment to the corresponding end section of an articulated bridge of the other of the two interconnected railroad cars, both end sections running in the transverse direction of the bridge.

Abstract: The object of the invention is a diaphragm for passsenger railway cars, which consists of a platform (5) and a diaphragm (36, 2, 3) disposed in tunnel fashion over the platform. The system is so constructed that it provides good protection for the interior against external influences even when the differences in pressure between the outside and inside are extreme. The tunnel-like diaphragm consists of an inner end frame (36) for fastening to one of two railroad passenger cars coupled together, an outer end frame (3) for cooperation with the outer end frame of the connecting platform of the second of two coupled railroad passenger cars, and a resilient member, especially a bellows (2) between the two end frames (36) and (3). The outer end frames (3) is suspended by springs (4a) directly on one of the two passenger cars, and the springs exert an outwardly directed force on the outer end frame (3).

Abstract: A gangway is provided between two railway cars or units of railway cars that are pivoted to one another, and that forms a continuous, stepless passage for all travel motions. The entire gangway is designed as a unit that is held in the central position to each of the ends of the cars facing one another with the ability to shift lengthwise, by a centering device, and is supported and guided on bridge bearings, and is mounted to be able to pivot around its vertical axis and also to be able to tip out of the horizontal plane. The bridge area of the gangway consists of a number of rigid rails placed parallel to one another at prescribed distances and able to move lengthwise, which are enclosed and guided at both ends in supporting profiles that are mounted and guided on the bridge bearings associated with them.
