The SBB (Swiss Federal Railways) awarded the main contract section for the four-track upgrading of the Olten–Aarau route in November 2014. The contract worth some 274 million Swiss francs was awarded to the Marti Eppenberg JV. It involves the roughwork for the Eppenberg Tunnel as well as its accesses in the Wöschnau and in Gretzenbach. The SBB embarked on the preliminary work for the tunnel and its access sections in early September 2014. The main operations are scheduled to start in spring 2015 and will last until late 2020. The upgrade to create a four-track route is being accomplished within the scope of the ZEB major rail infrastructure project.
In November 2014 the Deutsche Bahn commenced work on the Imberg Tunnel on the 60 km long new Wendlingen–Ulm rail route on the Alb Plateau. First of all construction pits were produced at both ends for the subsequent production of tunnel sections created by cut-and-cover. The tunnel will then be built by using the shotcrete method as from April 2015 onwards between the two cuttings produced by cut-and-cover.
The 27.3 km long New Semmering Base Tunnel (SBTn) is a major element of the new Austrian southern rail route. In spite of a four month long hold-up in construction lasting until June 2014 on account of objections by local residents and environmental organizations, the Austrian Federal Railways (ÖBB) still intend completing the project as scheduled in 2025. The “Gloggnitz Tunnel” section is being produced from the portal construction site at Gloggnitz and an intermediate point of attack in Göstritz (municipality of Schottwien) by mining means using shotcrete. As the ongoing preliminary operations were concluded on October 10, 2014, the tunnel drive will probably start from Gloggnitz in spring 2015 providing that all required permits are available.
