Light at the end of the tunnel – breakthrough of Eppenberg Tunnel
moreAfter an advance period of approximately one year, the Eppenberg Tunnel was broken through on February 2, 2018.
The Eppenberg Tunnel is part of the Swiss Federal Railway Line between Aarau and Olten which is being widened to four tracks. The tunnel was advanced with a mixed shield tunnel boring machine over a length of 2.6 km and will have a total length of 3.2 km long upon completion of the construction works. The Eppenberg Tunnel is scheduled to be put into operation by the end of 2020. It will provide a significant increase in capacity of the main artery from Zurich to Bern.
Together with partners, ILF Consulting Engineers was awarded a contract for the project works (basic design to construction design) and the site supervision works as part of an overall planning mandate for the 4-tracking of the Aarau–Olten railway line. In addition, the mandate comprises the railway technology works after completion of the civil works.
