Principle and effect of dynamic track stabilisation

Using an imbalance, the DGS stabilising unit produces horizontal vibrations crosswise to the track axis. The dynamic track stabilizer travels in continuous action on the track while the stabilising unit transmits controlled minor vibrations to the track grid via pressing rollers. At the right vibration frequency (32 to 35 Hz) the ballast stones begin to move and re-­arrange in a denser and homogeneous structure. At the same time, the unit applies a vertical load to the track. It increases the consolidation effect and allows for modifying the longitudinal level of the track.

The main parameters are:

  • Vibration frequency
  • Impact force
  • Vertical load
  • Working speed
