When a train runs over a snow-deposited track at high speed, the snow-flying phenomenon occurs even if the surface of the snow is wet. The pressure fluctuation according to running of the train is thought to be the factor of the wet snow-flying phenomenon. When bogies of a vehicle run over a snow-deposited track, the large pressure fluctuation is caused. Accordingly, we studied to control the pressure fluctuation. As the result of the model experiment, we clarified that modification of the body shape around the bogie was effective in the control of the pressure fluctuation.
