Project description:
The Mattsand total reconstruction project is located between St. Niklaus and Herbriggen over a length of 1235 m. The core element is the new construction of the crossing with additional structural measures for supplementary use. Due to signs of wear and tear, the substructure and superstructure must be renewed along the entire route. The track geometry will be optimized to maintain the clearance gauge, in particular the service route on both sides, by shifting the track a maximum of 40 cm towards the valley after the Bielzug culvert in the direction of Herbriggen. The drainage and the cable system (new signal box, NS & Telecom, safety systems) will be renewed along the entire route. Various engineering structures will be erected to realize the total reconstruction.
Requirements:
- Work during rail operations
- Work under traffic (railroad operation) with tight space conditions
- Complicated logistics as a result of restricted access routes and handling areas
- Two-shift operation (night and day work)
