  • the technical solution relates to a railway or tramway track with modular panels of a low noise barrier reducing noise and vibration and arranged outside the track.
  • noise barriers are most commonly used. These noise barriers are made of boards or panels placed along the railway or tramway track. Another option is using horizontal structural pads from noise and vibration absorbing materials, which fill the track space, or it is possible to use a combination of both types of measures.
