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.

Aviation with Microlight Aircraft

Switzerland is currently one of the few countries in the world that categorically prohibit the operation of microlight aircraft. The FOCA is considering a relaxation of this ban in response to a request from pilots. R+R was commissioned to investigate the interest in microlight aviation in Switzerland.

“Ecolight” aircraft, as they are known, have been permitted in Switzerland since 2005. This category only includes aerodynamically controlled light aircraft. Other microlight aircraft, such as weight-shift control (WSC) trikes, microlight helicopters or gyrocopters are still not permitted. Microlight aircraft with wing loading of less than 20 kg/m2 are totally prohibited according to the Aviation Ordinance. The Swiss Hanggliding & Paragliding Association (SHPA) has submitted a request to the FOCA for the authorisation of electrically-powered hang gliders. In connection with this request, the FOCA is examining the possibilities for authorising additional categories of microlight aircraft and for lifting the prohibition mentioned above. R+R was commissioned by the FOCA to examine the development of microlight aviation in selected neighbouring countries and to compile a study on the interest in microlight aviation in Switzerland.
Authorisation for microlight aircraft in Switzerland would in any case be linked to specific provisos. Due to Swiss conditions, for example, the mandatory use of airfields for aircraft that cannot be foot-launched, as well as some sort of pilot’s licence, are almost indispensable requirements. In the first instance, therefore, it was advisable to clarify the interest in motor-powered microlight aviation among existing pilots. R+R defined possible categories for these microlight aircraft as the basis for conducting a survey among pilots of motorised aircraft, gliders and hang gliders as well as flying schools and clubs. Over 1,600 pilots and 57 flying schools and clubs took part in the survey, which made it clear that there is a certain degree of interest in microlights.
