In both the cases the train operates on a straight track with 200 km/h speed of motion, which is the maximum operational speed of the locomotive. The main results of the problem solution represent time-variations of pressure and velocity recorded in defined locations in track vicinity and a report of the aerodynamic force affecting the reference cylinder in a horizontal plane within the train passage.
