The NRLA Gotthard Axis consists, in addition to the Gotthard Base Tunnel, of the 15 km long Ceneri Base Tunnel, the two single-track bores of which are to be augmented by bifurcation structures which will permit additional traffic links. Construction is well advanced; lining installation is already proceeding in parallel to tunnel-heading work, in order that, despite the difficult geological conditions, the still ambitious time-schedule can be met.
The DB Projekt Stuttgart-Ulm GmbH is forging ahead with the construction of the Boßler Tunnel as planned. It is the longest tunnel on the new Wendlingen–Ulm rail route with a length of 8806 m. The tunnel boring machine bearing the name Kätchchen reached the 1000 m mark late in the evening on June 18, 2015 in the eastern bore, which subsequently will house the Ulm–Stuttgart track.
The legal dispute concerning the award of the railway systems for the Ceneri Base Tunnel has consequences. An intensive review by the constructor, AlpTransit Gotthard Ltd (ATG), has concluded in mid-June 2015 that operational opening of the Ceneri Base Tunnel should now be planned for 2020 instead of 2019.

The TBM named “Kätchchen” used to drive the Boßler Tunnel began its work in mid-April, 2015. The machine built by Herrenknecht first tackled the eastern bore, which will one day accommodate the track running from Ulm to Stuttgart. It advanced from the start-up section at the Aichelberg portal up the Alb towards the access tunnel already produced at Umpfental near Gruibingen.
The second Metro Line (Metro Line B) in the French city of Rennes with 15 stations will be 13 km long. 8.1 km of this total will be driven mechanically and 2.4 km by cut-and-cover. The remaining parts...
Currently the Klaus chain of tunnels between the Klaus and St. Pankraz/Hinterstoder junctions, the Bosruck and the Gleinalm tunnels, which represent undeveloped gaps on the A9 Pyhrn Motorway, are...
The Granitztal Valley chain of tunnels represents part of the 130 km long Koralmbahn Railway between Graz and Klagenfurt. It is located in the 7.8 km long section between St. Andrä and Aich. The ÖBB-Infrastruktur AG has commissioned the Implenia (general management) and Hochtief Infrastruktur JV to execute construction. In early February 2015 the ÖBB-Infrastruktur AG also commissioned the production of the St. Kanzian chain of tunnels between Schreckendorf and Peratschitzen. The main elements are the 620 m long tunnel at Srejach and the 665 m long tunnel in Untersammelsdorf.
