    Sammanfattning : Computing the loads for a train passing a tunnel requires to predict both the external and the internal pressure variations in time, both of which are strong and quick for a non-pressure tight train. The key achievement of this work has been the development of 3D CFD Star-CCM+ overset mesh simulations capable of simulating the single train tunnel entry and tunnel passage as well as the two trains crossing inside the tunnel.
