(EN) The invention relates to a controlled-route vehicle, in particular a train, having at least one air passage (24) which is arranged in a wall (16) of the controlled-route vehicle. The air passage (24) has an inlet opening (28) for letting air into the air passage (24), wherein the inlet opening (28) is arranged in an outer side (26) of the wall (16), an outlet opening (32), through which the air can be let out into an interior of the controlled-route vehicle, wherein the outlet opening (32) is arranged in an inner side (30) of the wall (16), and a section (46) which tapers in the direction of the outlet opening (32) and is formed by an inner wall side (33) of the wall (16). As a result, improved transport of the air into the interior of the controlled-route vehicle (10) can be achieved in a structurally simple and inexpensive manner.
