Railway freight wagon with a sealing arrangement for a sliding cover

The invention relates to a sealing arrangement for the edges of a sliding cover (10) in a railway freight wagon, comprising an edge sealing (2) of elastic material, which is substantially C-shaped in cross-section and has the ends of its legs (4, 5) provided with engagement bosses (3). The vicinities of cover edges (1a, 1b, 1c, 1d) include two broached-bottom mating grooves (6) at a distance (W1) from each other for receiving the engagement bosses (3) of an edge sealing, whereby the edge sealing is in contact with the cover. The edge sealing has a central portion (7) of its C-profile compress against a wagon frame (9) while the cover is in a closed position (S). As the shape of a wagon frame changes during running, for example, the central portion rolls along the surface of a mating structure, thus reducing wear and tear.
