The invention relates to a vehicle, in particular a rail vehicle, in particular a rail vehicle, for a bidirectional operation at a nominal travelling speed above 160 km/h, in particular above 200 km/h, in a respective direction of travel comprising at least one vehicle module with a wagon body being supported on a running gear configured to run on a track defining a track level, the vehicle module defining a longitudinal direction, a transverse direction and a height direction. The wagon body has an outer skin defining a generally prismatic body section and a non-prismatic head section located at one of its ends, the vehicle module, at a transition between the body section, and the head section, having a maximum vehicle height dimension above the track level in the height direction. The wagon body, in the head section, has a flow separation section comprising a flow separation device, in particular a flow separation edge, the flow separation device, in particular, the flow separation edge, in a transversally central area of the wagon body and at least in an activated state, being located at a flow separation height in the vehicle height direction. The flow separation device provides a persistent separation of an airflow from the outer skin of the wagon body when the vehicle module runs at the travelling speed with the head section forming a trailing end of the vehicle module. The flow separation device, at least in the activated state, defines a generally concave flow separation section of the outer skin, the flow separation height ranging up to 50% to 65% of the vehicle height dimension, preferably from 25% to 50% of the vehicle height dimension, more preferably from 30% to 46% of the vehicle height dimension, even more preferably from 33% to 39% of the vehicle height dimension.
