In a subway station, train winds, which are generated by a train that acts as a piston against the tunnel air, adversely affect passengers or air-conditioning of the station. For reducing the winds, in this study, the air volumes of the blowers at Hikarigaoka Station, which are used for longitudinal ventilation in the tunnels, are dynamically controlled in three ways - increasing, decreasing or increasing-decreasing ventilation tuned to the train transit. The unsteady air velocities are measured in the tunnels and at the staircases, and then the air volumes are estimated. Results show that (i) the time histories of the unsteady air velocities are in good agreement with the existing theory, and (ii) the ratio of the reduced train-wind air volume at the staircases to the air controlled volume by the blowers are about 50% at arrival or 70% at departure.
