Switzerland, Canton Aargau - ch/93


SBB awarded Implenia of Wallisellen the EUR137 million contract (CHF145 million) to build the new twin-track Boezberg railway tunnel, replacing the existing Boezberg tunnel in Canton Aargau and allowing containers with a corner height of 4 m to be transported along the route.

The northern portal of the new tunnel is located near Effingen, while the southern one is by Schinznach-Dorf. Installation sites are being set up at both locations. The main work will carried out by a TBM starting at the Schinznach-Dorf site.

Construction is scheduled to start in spring, 2016, and the tunnel is due to become operational in 2020.

As well as building the new track, the contract includes installation of some of the electrical equipment (rail technology). It also includes the conversion of the existing twin-track tunnel, which is not big enough for 4 metre containers, into a service and rescue tunnel, as well as all of the implementation planning. Five cross-passages will provide emergency access from the new to the old tunnel. The conversion work will take until 2022.
