edilon)(sedra successfully installed 4 maintenance-free level crossings on the main line Paris-Lille, in Breteuil, France.

The old level crossings required weekly inspection, frequent maintenance and had to be renewed every 3 years.

In a short weekend shift the 4 new level crossings were installed, applying edilon)(sedra Corkelast® LCS (Level Crossing System). Prefabricated slabs were mounted on a solid layer of subsoil and geo-textile. Thereafter a bottom-up rail installation commenced with shims for alignment. The edilon)(sedra Corkelast® elastomer was poured to embed the rails and give them their world famous continuous support.

Since the renewal there is no requirement for frequent and costly inspection visits. The train speed has been increased to 160 km/h in the first stage, and the accessibility and safety are significantly improved.

Corkelast® ERS for reduction of rail wear in curved tracks

edilon)(sedra has recently been asked for a rail replacement job in the historical city centre of Gent in Belgium. The old and rigid filler block system caused heavy rail wear in the curved part of the track.

Therefore the old track is replaced by the elastic and durable rail system edilon)(sedra Corkelast® ERS (Embedded Rail System). This homogeneous and robust rail fastening over the full length of the curved track, minimizes future rail wear and contributes to a favourable LCC-balance. The system offers track gauge stability especially in curved track without the use of gauge bars. Furthermore it offers optimal reduction of noise & vibration, which is an important aspect for this historical and densely populated part of the city.

Poster vibration attenuationWe recently released this poster, which gives you further in-sights in resonance frequencies and insertion loss values of our core rail fastening systems and products. More information? Or do you want to receive the poster? Please contact us.

edilon)(sedra investigates sustainable biobased polymers for railway systems edilon)(sedra, in cooperation with Wageningen UR and Croda, is working on the development of next generation polymers for elastic rail fastening systems. The goal of the project is to develop environmentally-friendly biobased polymers which cure into an elastic rubber-like compound within a limited time.These biobased polymers can be applied as elastic sound and vibration-reducing materials. The project team is studying various chemical research routes. The final material should have an optimal worksite processability. In addition it should meet specific mechanical and adhesion requirements.

BPM programmeThe project is part of the large-scale research programme Biobased Performance Materials (BPM). The goal of the BPM programme is to develop high-quality materials based on biomass; materials that are increasingly applied in practice. The research focuses on two types of polymer materials: polymers produced by plants and polymers from biobased building blocks produced via biotechnology or chemical catalysis. The BPM programme is partly financed by the Top Sector Chemistry and is led by Wageningen UR Food & Biobased Research.

State-of-the-art Ankara High Speed Station constructed with Corkelast® ERS We are pleased to inform you that TCDD Turkish State Railway Authorities have decided to take advantage of edilon)(sedra Corkelast® ERS (Embedded Rail System) for their new iconic railway station in Ankara, Turkey. The high speed track construction will be completed by end of May 2016.

TCDD’s main technical reason for selecting ERS is the fact of being 100% in conformity with the CEN 13481-5. Respective ERS-documentation such as reference letters from various railway authorities, complete CEN-test reports, etc. had been provided confirming the outstanding track record and unrestricted applicability.

As the station building also has a shopping mall, 5 star hotel, conference center, etc. a noise & vibration study had been conducted in collaboration with Prof. Mehmet Çalışkan / METU, Ankara in order to verify the behavior of our ERS with Trackelast® STM/RPU in accordance to the technical requirements.

Innovative strategy for extension railway line Toyama, Japan Ten years after edilon)(sedra installed 1.163 meter of Corkelast® USTS (Urban Slab Track System) in Toyama Japan, the city has a very innovative strategy to further extend this successful tram system.

In the past the city centre of Toyama was practically divided in half by a railway line, and new tram operations started up in the part which still had no tram. To bring people living in the suburbs into the city, a disused railway line was refurbished for tram operation and laid into the city centre (to the railway station). This new tram line (Seaport Line) for which the slab track system was installed by edilon)(sedra, is operated by Toyama Light Rail Co. Ltd., opened in 2006.Nowadays there are two standalone systems which are only sepa-rated by the railway lines. With the extension of the railway line in Toyama for the Shinkansen and Toyama railway station, the idea emerged of connecting the two tram systems with a new under-pass which has yet to be built. It is planned to connect the existing

terminus of each system at the railway station in 2020. The vision would then become reality, and Toyama would have one continuous high-performance tram system.In the Seaport Line project we were joined by Hanning & Kahl as partner from the European Transportation Technology Group (TTG). Together, we demonstrated that European technology offers ideal solutions for safe, modern, long-lasting and thus economically- efficient tram systems.

edilon)(sedra participated in the 2016 MiddleEastRail exhibition for the third year running. We were happy to recognise that the exhibition has developed in to a truly international event.

The exhibition ran for two full days, most of the time the stand was very busy. There were clients, technical advisors, principles and decision makers, all who were keenly interested in our embedded rail technology, especially the edilon)(sedra Corkelast® Embedded Block System (EBS).

EBS was identified as a compliant system to track works that were exposed to the torrential rainfall. It was identified that rainfall in the Middle East region, though very infrequent, often exceeds more than 250mm in a day. When this occurs, other traditional track forms are often not suitably designed to accommodate the rainfall.

Enquires for the edilon)(sedra track systems came from the whole Middle East. edilon)(sedra participation in the 2016 Middle East Rail exhibition was a success, and we look forward to meeting our old friends as well as our new ones during this promising 2016.
