On Saturday, April 15, 2023, more than 20,000 visitors took the opportunity to participate in the «tunnel festival» and inspected the new third tube of the Gubrist motorway tunnel Bicycles were available for transiting the whole length of the tunnel and were in constant use from 10 a.m. to 10 p.m. in both directions. Many guests also enjoyed the tunnel atmosphere by taking a ride on the rubber-wheeled sightseeing train. In addition, the program included a show presented by the emergency services, tours of the huge control centers and a wide range of catering options.
Early on Thursday morning, April 20, 2023, the third tube of the Gubrist tunnel was commissioned. Westbound traffic has been flowing through the new tunnel tube since shortly before 4 a.m. As part of the drainage, surfacing and foundation work has not yet been completed, some construction space is still required in Weiningen. Therefore, for the time being, only two lanes are available for traffic in the new tube. The official opening with the release of the third lane will take place on July 3, 2023 in the presence of Federal Councillor A. Rösti.

The new third tube of the Gubrist tunnel will start operating after a "silent opening" during the night of April 22, 2023. A major public festival will take place one week earlier on April 15, 2023. The formal opening event with Federal Councillor A. Rösti is envisaged for July 4, 2023, when all three westbound lanes will be available to road users.

The commissioning of the third tube of the Gubrist tunnel has been postponed until spring 2023 due to the current global economic situation (Covid).
During the night of April 22/23, 2023, there will be a "silent opening" of the third tube to regular traffic. A public festival and the authorities’ event are expected to take place in mid-April 2023.
In early May 2023, the renovation work of the existing second Gubrist tube will start. Westbound traffic (direction Bern) will be accomodated on two lanes in the new third tube, while eastbound traffic (direction St. Gallen) will occupy two lanes in the first tube.
Maintenance project Hagnau – Augst
The GS-DETEC (General secretary of the Federal Department of the Environment, Transport, Energy and Communication) has approved the "Operations Center South East" project. No complaints were received against this decision. Thus, details concerning the construction process of the new operations center next to the east portal of the Schweizerhalle tunnel are now being planned. Procurement of services is expected to take place in 2023.

ERTMS UK Cost Analysis Digital Railways – Reducing Costs
Network Rail, Britain’s railway infrastructure operator, pursues a strategy of digitalising the national railway signalling systems by replacing the current interlocking technology, improving traffi cmanagement and introducing the European Train Control System ETCS. R+R validated the programme cost estimates and compared them to similar programmes in other European countries.
The validation of the British programme cost estimates pointed at potentials for reducing costs particularly in the sector of central signalling installations. Accordingly, the focus of the international cost benchmarking was set on ETCS level 2 projects and programmes, as well as on the replacement of central interlocking systems.
In a team with Morten Søndergaard, the director of the Danish signalling programme, Emch + Berger and Oskar Stalder, R+R investigated with the benchmarking partners on how to achieve an economically favourable programme through precursory measures, suitable specifi cations, contract strategies and appropriate project organisation. Our findings are based on the experience gained in comparable projects in the United Kingdom, Denmark, Norway, Sweden, the Netherlands, Germany, France, Italy and Switzerland.
