The UST 79 S universal tamping machine is equipped with two bogies for working travel and with a three-axle road chassis and a semitrailer for transport by road.

The result counts
When it comes to tamping the ballast bed, our aim is efficiency and sustainability. Homogenous compaction is not enough. Our aim is to compact the track ballast as much as possible, thereby ensuring a stable track geometry, anticipating settlements, and maintaining the target geometry in the long term. On top of it all, we offer the Dynamic Track Stabiliser: it anticipates initial settlements in a controlled manner, with spatial compaction making the track geometry last longer.
Combined with Dynamic Overlifting, we target the “track’s memory” to prevent faults from reoccurring.
