When a train rushes into a tunnel at high speed, a compression wave is generated in front of the train. It propagates through the tunnel, bursting out from the exit of the tunnel to the atmosphere as a bang. The strength of this bang is proportional to the pressure gradient of the compression wave which propagates through the tunnel. This study investigates the relation of the train form and the speed to the compression wave that is formed in the tunnel. The parameters of the waveform that depend on the train form and the speed are derived from the similarity rules. The estimating method of the compression wave which can be used in the wide range of speed is suggested.
