When a high speed train enters a long tunnel, compression wave is generated in front of the train. This compression wave propagates in the tunnel at the speed of sound. When the wave arrives at the end of the tunnel, a pulsed compression wave, called 'tunnel micro-pressure wave', is radiated from the exit. This micro-pressure wave causes environmental problems especially in high-speed Shinkansen Expresses. In recent years, however, with the improvement of vehicle performance the running speed of train is increasing, and this problem of the tunnel pressure wave has also occurred by conventional limited express. This study deals with the pressure wave formation and propagation phenomena by the experiment using an apparatus with diaphragmless driver acceleration, and small train nose models of limited express in combination with a short tunnel and a station model.
