Transition zones in railway tracks are locations with discontinuity in the vertical support, such as the ones at bridges, culverts and tunnels. In such locations, the vertical support of structures is varying, which causes discontinuity of stiffness, different settlement paces and different velocity of wave propagation. These changes will cause geometry difference in the transition zone, and consequentially increase of the dynamic forces. This can result in damages, especially in the ballast as this is one of the most vulnerable components of track structure.
