What is so cost-efficient about dynamic track stabilisation?

Raising the sleepers during track tamping reduces the track grid’s lateral resistance in the ballast bed. The dynamic stabilizer anticipates traffic loads in a controlled way, exerting rather low stresses on the ballast bed. The controlled settlement increases the track’s resistance to lateral displacement considerably.

As a result, there is no need to impose speed restrictions after tamping. The homogenisation of the ballast bed secures the track firmly in position. It ensures that the track geometry is more durable. In addition, the action limit is reached much later and intervals between maintenance are extended. Maintenance costs are reduced.
