<p>The rail vehicle has a roof, which comprises beads (1), on which the rails (2) are arranged for fastening devices, such as air conditioners or power converters. The rails have a C-shaped cross section. The rails are welded to the beads, where the beads run parallel to each other and parallel or orthogonal to a longitudinal axis of the rail vehicle. The beads are curved outwards. The beads are formed from a metal sheet (3) by a forming process. An independent claim is included for a method for manufacturing a roof of a rail vehicle.</p> |
