The train wind is caused by the movement of the trains in the subway system. For the purpose of the reduction of the train wind influence, it has been proposed to build some devices such as the air shaft and the cross vent etc.. In this study, the effect of using these devices has been investigated by observing the two-dimensional flow on the water table ; features of the air flow in the subway system can be observed as the water flow in this experiment. The case of double tunnel with a single track is tested by moving model trains in the water table. The results show that : 1) The air shaft is an effective device to reduce the train wind influence at the station for any cases of the arrival of the train. 2) The cross vent is not as effective as the air shaft. When the train passes by, the change in the direction of the air flow occurs in the cross vent. The air flow comes and goes in the cross vent while the train moves toward and away from the cross vent.
