Hi all. I need to model a train entering a tunnel with varies speed that is from low speed to high speed. But i am not sure what speed constitute a high speed train. What is the limit/range for high speed train. I am currently starting the model with a speed of 22m/s.Thanks for advice.

The german ICE or the france TGV travel with up to 300 km/h, which is 83.3 m/s.

Hello, When a train goes in a tunnel, there are some pressure fluctuations. If the pressure increase is too high, there will be some consequences on passenger confort. So your maximum speed is a function of the tunnel geometry, the train, ....
