Continuous action
  • Variable maintenance of plain line tracks and turnouts
  • Maximum flexibility in the turnout thanks to variable use of 16 tamping tines, 3-rail lifting, and 4-rail tamping technology
  • The world's leading tamping technology - tested under various operating conditions on every continent
  • High track geometry durability and resistance to track buckling thanks to dynamic track stabilisation
  • Reduces speed restrictions: optimised availability of the infrastructure following maintenance and dynamic track stabilisation
  • The frame is designed to maintain the heaviest types of superstructure (heavy haul lines)
  • High availability thanks to a top speed of 100 km/h during running mode under own power
  • Approved for line category C2 (axle loads ≤20 t)

4-rail tamping

This mode uses four tamping unit segments. The outer segments can be slewed out far enough that the long bearers of the diverging rail in the turnout can also be tamped. This is an ideal supplement to automated synchronous 3-rail lifting. Positioned on transverse guide columns, the inner tamping units can be displaced laterally. This enables them to be operated in the area inside and outside the respective rails. All four tamping units can be turned and thus adapted to the slanting position of the sleepers.
