H. in the track with the rail.
  • transition areas on all railway lines ie, for example, transitions from bridges to tunnels, bridges to Planum, planum to tunnel or bridge section to bridge section with pillars in between.
  • the rail fastening system must ensure that the push-through resistance in the rail longitudinal direction is reduced so that thermal and operational longitudinal movement of the rail does not affect the bridge structure or any other substructure.
