RAIL VEHICLE WITH AIR-CONDITIONING DUCT IN THE ROOF REGION AND METHOD FOR CONSTRUCTING A ROOF REGION OF A RAIL VEHICLE

摘要

A rail vehicle has a roof region. In a longitudinal direction of the roof region, an air-conditioning duct is laid and which is bounded with respect to a passenger compartment by an inner ceiling. When the air-conditioning duct is composed in its longitudinal direction of at least two air-conditioning duct elements, the two air-conditioning duct elements are connected to one another by a sealing frame which can be pre-positioned. Furthermore, a method for constructing the roof region for such a rail vehicle is specified.
