Abstract: Interconnected train cars (ZUV) with at least two rail vehicles (WA1, WA2) coupled to each other, between which there is a passage (UEB) with at least two gangway bellows (WB1, WB2), which can be connected to each other and which each have several bellows frams (BR1, BR2, BR3, BR4), and the passage (UEB) has additional passage plates (UB1, UB2, UB3, UB4) and a support (ABS) for the passage plates (UB1, UB2, UB3, UB4), with this support being able to move on a sliding plate (GLP) arranged between the rail vehicles (WA1, WA2) above a coupling device (KUP), wherein there is at least one pile-up prevention device (AC1, AC2) at the end regions of the rail vehicles (WA1, WA2) coupled to each other, with the pile-up prevention devices (AC1, AC2) each extending essentially over the entire vehicle width, the bottom edges of the bellows frames (BR1, BR2, BR3, BR4) being arranged over the upper edges of the pile-up prevention devices (AC1, AC2), and the sliding plate (GLP) being arranged under the bottom edge of the pil

Abstract: A bowl-shaped or plate-shaped structural element, consisting of a first layer (A), an intermediate layer (C), and a second layer (B), wherein the first layer (A) and the second layer (B) are profiles (1a, 1b) having anchorage couplers (2a, 2b) projecting into the intermediate layer (C), which couplers regionally interlock with the anchorage couplers (2a, 2b) associated with the respective opposite layer (A, B), and the space between the profiles and their anchorage couplers is filled with a material that is solid and cohesive per se.

Abstract: The invention concerns a train (ZUV) with at least two intercoupled railway vehicles (WA1, WA2), between which a junction (UEB) is provided that has at least two interconnectable bellows (WB1, WB2), each comprising a number of bellows frames (BR1, BR2, BR3,BR4). Said junction (UEB) also has junction metal sheets (UB1, UB2, UB3, UB4) and a support (ABS), which is provided for these junction metal sheets (UB1, UB2, UB3, UB4) and which can be displaced on a friction plate (GLP) mounted between the railway vehicles (WA1, WA2) via a coupling device (KUP). At least one anti-climbing protective device (AC1, AC2) is provided on each of the intercoupled end areas of the railway vehicles (WA1, WA2), and the anti-climbing protective devices (AC1, AC2) each essentially span the entire width of the vehicle.
