Abstract
Transition zones in railway tracks are areas with substantial variation of track properties (e.g., foundation stiffness) encountered near rigid structures such as bridges, tunnels or culverts. These zones necessitate special attention, mainly because they:
• Require frequent and expensive maintenance activities.
• Cause reduced availability of the railway track.
