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.

A4 KLEINANDELFINGEN – WINTERTHUR INTERSECTION ELIMINATION OF BOTTLENECKS

Regular difficulties due to traffic overloads must be expected during the morning and evening peak hours on the A4 between Winterthur and Kleinandelfingen. The capacity of the existing road, which has one lane in each direction, is no longer adequate for the volume of traffic. This is unsatisfactory in terms of road safety. Shortcomings such as the lack of a separating barrier between the directions repeatedly cause serious traffic accidents.

When the section of the A4 between Kleinandelfingen and Winterthur-North was originally built, an extension to provide four lanes was planned (General Project approved in 1973). Due to resistance from the affected residents and the objections that were submitted, only the two western lanes were built and commissioned in 1996 and 1999/2000 respectively. The enlargement of the A4 between Winterthur and Kleinandelfingen to provide a national highway that meets the standard, with two lanes and one hard shoulder in each direction, is an element of the «Programme to Eliminate Bottlenecks on the National Highways Network».

The development project comprises various major structures such as bridges, overpasses, underpasses, coverings and road runoff treatment plants, with the Weinlandbrücke bridge over the Thur which is outstanding in many respects. In parallel with the enlargement work, the existing structure is to be repaired and adapted in line with currently valid standards and guidelines. For this reason, the project design work is divided into the maintenance concept, the concept and project for the measures to be taken, the main execution project and the detailed project.

R+R is assisting the client by providing support for FEDRO’s overall project management in the areas of project management and project controlling, and with selected issues such as the assessment of alternatives and cost-benefit analyses.
