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.

N1, Extension of the Zurich Northern Bypass

On September 22nd, 2020, the third tube of the Gubrist motorway tunnel was broken through after 1,000 days of construction work and an excavation length of about 3,000m. Thus, an important milestone of the N1 Zurich Northern Bypass extension project was finally reached.

However, the work continues. Within the next two years, the construction of the roadway, the interior fittings and the installation of operating and safety equipment will follow. After completion of the third tube, three lanes will be provided for Bern-bound traffic. Commissioning and opening for regular traffic are expected to take place at the end of 2022.

MOTORWAY MAINTENANCE PROJECT A1 EFFRETIKON – OHRINGEN

A 12 km stretch of the A1 motorway between the exits Effretikon and Winterthur Ohringen is to be refurbished. Moreover, by introducing up-do-date signalling technology, an optimisation of the traffic flow on the section Winterthur Töss – Winterthur Nord junction is to be achieved.

Stretching an approximate 12 kilometers in length, the A1 motorway section between Effretikon exit and Winterthur Ohringen exit ranks among the most congested motorway sections in the Swiss motorway network. The number of vehicles using it amounts to 100‘000 per day. The section in question has been in continuous service since 1974 and no significant restorative measures have been undertaken since then. In the context of the maintenance project «A1 Effretikon – Ohringen», the section is thus going to be refurbished in the coming years. In particular, there will be a renewal of parts of the roadway and the operation and security installations, in order to comply with current regulatory standards. Additionally, several adjacent structures require corrective maintenance measures to be carried out to warrant full operability of the constructions until the end of their expected life spans.

The FEDRO aims to effectuate a smoothing out of the traffic flow in the Winterthur area by installing up-to-date signalling technology. The project at hand will see to the implementation of according measures between the Winterthur Töss exit and the Winterthur Nord junction. Work on preliminary maintenance measures is set to begin in mid-May 2019. The principal part of the corrective maintenance will be carried out from 2020 to 2022. As part of a set of precursory measures, the Töss Bridge, the overpasses Zürcherstrasse Süd and Grafstal, three structures at the Effretikon exit, the retaining wall Pfahlwand Rossberg and the traffic light system Salomon- Hirzel-Strasse were refurbished between 2015 and 2017. Total project costs amount to 228 Mio. Swiss francs.

Holding mandates as project-owner support unit and construction supervisor, R+R supports and advises the general project management team of the Federal Roads Office in project management, controlling and the assessment of selected issues for the entire duration of the project.
