This compartment of a railway vehicle defines an interior volume and comprises: a cover movable between an open position, in which the cover is offset from the interior volume, and a closed position, in which the cover covers the interior volume and at least partially delimits that interior volume, a bar, a central region of the bar extending out of the interior volume, and a hinge defining the path of the cover between open and closed positions. The cover is rotatable about an axis of the bar between its open and closed positions, the bar forming a pin of the hinge.
