Pressure waves are generated when high speed train runs through the tunnels. These pressure waves not only affect passenger"s health, but also can cause fatigue failures on the vehicle structure. The current high speed train should run on the conventional lines. In this study, pressure fluctuations by the high speed trains such as G7 Korea High Speed Train and Korea Train eXpress are measured in the cabin and the carbody surface when they pass through the tunnels. The measured results are analyzed and the related parameters are investigated.
