When a high-speed railway train enters a tunnel, it generates a compression wave ahead of it. Then the wave is propagated through the tunnel, and causes a pressure pulse which is called a micro．pressure wave when it arrives at the tunnel exit. In the past, compression waves generated by Shinkansen trains entering various tunnels were measured by West Japan Railway Company. The present paper shows the results of prime parameters such as pressure rise and waveform of the compression waves measured at a few points in some Shinkansen train-tunnel systems. Using these results, the attenuation and distortion of propagating compression waves in the tunnels are discussed.
