A gangway bellow includes an outer bellow presenting corrugations forming a plurality of valleys presenting each a valley top portion facing upwardly and connected at each end to a valley top corner forming a junction between the valley top portion and a respective bellow side. The gangway bellow further includes at least one drainage channel so that liquid accumulating into at least one of the valley top portions flows through the at least one drainage channel along the respective bellow side.

A grating for a support structure includes a piece of metal including a perimeter edge and a surface bound by the perimeter edge. The piece of metal defines an array of uniform surface modifications on the surface of the piece of metal. The uniform surface modifications are arranged in a repeated pattern across the surface. The repeated pattern of uniform surface modifications is consistent across the surface but for at least a pair of spaced apart areas of inconsistency where the uniform surface modifications are not formed in the surface. Each area of inconsistency is surrounded on all sides by the array of uniform surface modifications. The pair of areas of inconsistency provides an indication of where to attach a structure to the grating.

The invention relates to a rooftop crossmember (31) structurally bridging rooftop side members (32) at an end of a rooftop (11) of a railway passenger car (2, 3) adjacent to a gangway bellow (4) and comprising a plurality of structural elements such as an upper structural element (40a) and a lower structural element (40b). The lower and upper structural elements (40a, 40b) are shaped and attached together for forming a hollow structure integrating means for performing non-mechanical functions such as a water drainage channel (34) for evacuating water accumulating on the rooftop (11) on the top part of said gangway bellow (4), and at least an electric housing (29).
