An analysis is made of the compression wave generated when a high speed train enters a tunnel. Operations in the near future are expected to be at Mach numbers M ranging in value up to 0โข4. Non-linear steepening of the wave in a very long tunnel exacerbates the environmental damage caused by the sub

A compression wave generated when a high-speed train emerges from the exit portal of a tunnel, causes an impulsive noise called micro-pressure wave. There are various countermeasures to reduce the micro-pressure wave, the most e!ective one being the proper design of the nose shape of the train. In t
