Map with all coordinates: The Eppenberg Tunnel is a railway tunnel under construction in the Canton of Solothurn , Switzerland . It is part of the Future Development of Railway Infrastructure (ZEB) expansion program and strengthens the line from Aarau to Olten in the Schönenwerd - Däniken section .
planning
A particularly delicate bottleneck in the Swiss rail infrastructure for rail traffic is in the section between Aarau and Olten, which has only two lanes at Eppenberg-Wöschnau , Schönenwerd and Gretzenbach . The route has to be shared by international long-distance traffic (with ICE and TGV Lyria ), dense national passenger traffic and freight traffic by rail. This is why the full connection between the four-lane routes that already exist near Aarau and Olten has high priority when expanding the infrastructure.
The main purpose of the tunnel is to increase capacity. With two additional lanes and a better route, train traffic can be accelerated and expanded to include additional regional trains.
As a second councilor, the Council of States adopted the so-called ZEB law with 43 votes to 0 in the spring session of 2009, which forms the basis for financing the Eppenberg tunnel. Due to the large financial requirements for the new NEAT rail link through the Alps , construction of the Eppenberg tunnel could not begin until 2015.
Construction project
The project is planned and managed by SBB Infrastructure in Olten. The Eppenberg tunnel is the core of the approximately 3.5 km long new line, which will pass south of the center of Schönenwerd and will have a much more stretched course compared to the existing line, which has a tight curve in Schönenwerd. The western tunnel portal is located in the area of the municipality of Gretzenbach. Part of the future tunnel with the underpass under the road will be built there using opencast mining. Between the tunnel portal at Gretzenbach and from Däniken station to Dulliken station , the railway line has four lanes.
The tunnel will be 3114 meters long, this length is divided into the 125 meter long opencast section at the Gretzenbach portal, the 2616 meter long tunnel section (around 600 meters with the Hydroshield method) and the 373 meter long opencast section at Wöschnau portal.
The eastern tunnel portal will be built to the west of the Wöschnau district. In the vicinity of the future underpass under Hauptstrasse 5 Lausanne – Olten – Aarau – Waldshut, a deep cut will initially be created in which the tunnel boring machine will be assembled, which will excavate the main part of the tunnel.
In front of Olten, two unbundling structures are planned as a further component of this expansion step , which will allow largely crossing-free rail operations at the Olten junction .
construction
In advance, the SBB built a new signal box in Wöschnau for traffic management during the construction period.
In autumn 2014, work began on the double construction site near Wöschnau and Gretzenbach. This included clearing, earth moving, slope protection, demolition work, road construction and other measures. The Gretzenbach received a new creek bed. The substructure for the additional track began at Däniken.
On May 2, 2015, a tunnel construction festival with the official groundbreaking took place on the construction site near Wöschnau , attended by Federal Councilor Doris Leuthard , the SBB Group Management , the Government Council of the Canton of Aargau and the Government of the Canton of Solothurn.
ARGE Marti Eppenberg received the contract for the building . The construction company Huber from Eppenberg-Wöschnau is engaged in work. The new tunnel is scheduled to go into operation in 2020.
The excavation of the tunnel will be used to fill the dismantled hazardous waste landfill Kölliken .
