A1, Extension of the Zurich Northern Bypass

The main construction work for the Weiningen motorway exit and the covered road section will start on August 16, 2021. The Weiningen exit will be relocated and moved around 200m closer to the Limmattalerkreuz junction. In addition, all three Gubrist tunnel tubes will be extended by a new 100m covered motorway section. This will reduce the noise and pollution levels of the adjacent residential areas. From mid-August, the top pavement layer of the roadway in the new third Gubrist tunnel tube will be installed over a period of approximately 3 weeks. Thus, most of the construction work will have been completed. In autumn 2021, installation of the traffic control and safety systems for the third Gubrist tunnel tube will start.

R+R has moved

Since June 1, 2021, the R+R offices have been moved into new premises on the 6th floor of the Duplex building in Baden at Brown Boveri Strasse 12. As before, we are still at a very central location within the city of Baden. As you notice, we also took the opportunity to update our website. We hope you enjoy the new content, and we look forward to welcoming you in our new offices at the next opportunity.

Oslo T-bane: CBTC project reaches important milestone

Oslo has an extensive metro network, the oldest in Scandinavia. Five lines serve 101 stations, and, in the central section, trains run every minute. Today, three different interlocking technologies are in use, some of which are already quite old. Over the next few years, operations will be converted to the communication-based train control system CBTC. At the beginning of February, four suppliers submitted initial offers for the system’s introduction and operation in the following twenty-five years. R+R supports the customer Sporveien with the evaluation of offers and the upcoming negotiations.

ETCS introduction in Finland

As part of the Europe-wide introduction of the interoperable train control system ETCS, Finland is examining the right strategy for the country. Fintraffic Rail develops pioneering digital solutions under the “Digirail” label. By the beginning of 2020, a wide range of variants had been presented, for which R + R provided rough estimates of the life cycle costs. In the meantime, Fintraffic Rail has derived an ideal solution and has examined it in depth. At the beginning of 2021, R + R developed a refined cost estimate and compared it with the costs of a fallback solution. In addition, R + R supports the assessment of cost uncertainty and the cost consequences of risks.

EXPEDIENCY ASSESSMENT 2. TRAMWAY AXIS BERNE CITY CENTRE

Today, the entire tram traffic in the historic center of the city of Berne is concentrated on the Marktgasse and Spitalgasse route. This section connects the eastern and western parts of the tramway network. A second tram route is expected to reduce the strain on the central network segments and to increase the operational reliability.

Berne’s historically grown tramway network is focusing on the central railway station. All feeder lines in the station area are using a single corridor, passing through Marktgasse and Spitalgasse in the upper part of the old town and thus through a central area of the UNESCO World Heritage perimeter. As this main axis is at the same time the most important shopping street in Berne’s historical center, conflicts with pedestrian traffic and supply logistics are inevitable.

With the planned construction of a new tramway line to Ostermundigen, the unsatisfactory situation will become even worse. After completion, this network section will have to accommodate 46 trams and 12 busses in each direction during peak hours. To alleviate the strain on the main axes and to establish a network less prone to operational limitations, plans for a second tramway axis between the central railway station and the “Zytglogge” clock tower are prepared.

R+R developed proposals for the alignment of the second axis as part of an expediency assessment, offered technical support and evaluated the layout options. The optimal solution suggests an alignment through Speichergasse and Nägeligasse. This would result in a substantial reduction of strain on the existing axis and, in the event of an incident, would allow for the rerouting of all tram lines onto the new route. In addition, R+R examined alternative options to infrastructure extension and developed possible measures to optimise the existing network and improve operational efficiency.
