A calculation method for pressure changes of a high-speed train passing through a tunnel has been developed, which can calculate by superposing pressure waves of a train entering into a tunnel and pressure changes of a train side without solving the differential equation of one-dimensional unsteady compressible flow. This report explains this calculation method, and shows the verification by the measurement and the example of the maximum pressure change calculation for passenger's comfortable level, of which the parameter is the time of the other train entering into a tunnel.
