The standard profile consists of a horseshoe profile with a total height of 4.67 metres and has a profile size of 21.25 m2.
As part of the construction project, the tunnel section in the area of the Solis portal will be renewed using the open-cut mining method. In line with other projects on the Albula line, this includes widening the profile to the new clearance gauge. The retaining wall on the uphill side and the wing wall on the downhill side will also be demolished and rebuilt and the tracks renewed.
Construction work is expected to begin in February 2024 and last until autumn 2025.
We would like to thank the Rhaetian Railway for awarding us the contract and look forward to working with them!
