Dynamic stabilisation has become indispensable to sustainable track maintenance. This is all the more important as traffic loads increase. Now, technological refinement brings further improvements for dynamic machines.
The ballast bed must be homogeneous and stable to fulfil its function: to distribute the dynamic forces produced by rail traffic into the formation, ensuring that the track geometry is maintained for as long as possible. The objective of dynamic track stabilisation is to produce a homogenous ballast bed after the track has been maintained using a tamping machine.
