The invention relates to a vehicle, in particular a rail vehicle, for a bidirectional operation at a travelling speed above 120 km/h, in particular above 160 km/h, in a respective direction of travel comprising at least one vehicle module (102) with a wagon body (103) being supported on a running gear (104) adapted to run on a track (105) defining a track level. The vehicle module (102) defines a longitudinal direction, a transverse direction and a height direction, the vehicle module (102) having a vehicle height dimension above said track level in the height direction. The wagon body (103) has an outer skin (103.4) and comprises a head section (103.2) located at one of its ends. The wagon body (103), in a roof section of the wagon body (103), has a flow separation section (103.6) comprising a flow separation device (103.7), in particular a flow of separation edge (103.9). The flow separation device (103.7) has a height extension in the vehicle height direction and provides a persistent separation of an airflow from the outer skin (103.4) of the wagon body (103) when the vehicle module (102) runs at said travelling speed with said head section (103.2) forming a trailing end of the vehicle module (102). The height extension of the flow separation device (103.7) ranges up to 30% of the vehicle height dimension, preferably from 2% to 30% of the vehicle height dimension, more preferably 5% to 25% of the vehicle height dimension, even more preferably from 5% to 20% of the vehicle height dimension, of the vehicle module (102) in the flow separation section (103.6).
