Highest mass-spring system using Sylomer® in Europe
- The track section is 420 metres long: a stretch of 288 metres is laid as slab track; 100 metres of this are in a tunnel.
- The altitude of the village of Samedan is 1700 metres above sea level
- Unusual geological conditions are also present: the tunnel and track are located in ground water
- Temperatures can fall as low as minus 30 degrees Celsius in the winter months
The Getzner solution
The Rhaetian Railway is the first to use a slab track in the form of a mass-spring system: a 288 m long "trough" that lies in ground water is the key element along the lowered length of track. It has been executed as a full-surface bedded mass-spring system.
To provide complete dewatering of the surface, lateral water channels and four pump pits were installed, two of which are heated during the winter. Getzner also installed strips of drainage matting in the corners along the entire length of the trough to catch any water entering via the joints. Together, these two measures ensure controlled and comprehensive dewatering of the mass-spring system.
