Unique and cost-effective level crossing solution in The Netherlands

edilon)(sedra recently installed a unique level crossing solution in Rotterdam, The Netherlands. Constructing the level crossing in this method resulted in significant savings for the contractors, because the installation no longer required the cutting and welding of rails.

The project included the extension of an existing level crossing by a 3 m LCS-L slab. Normally such a slab is placed directly on the split. In this case the slab is stabilized by means of grouting. Injection holes were mounted in the slab, as well as adjustment options in order to vertically adjust the slab by means of hydraulic jacks.

In addition, the use of stepwise displacement of the LCS-L slab, it was passed under the rails and positioned. Thereafter, edilon)(sedra Corkelast® elastomer was poured to embed the rails and give them their world famous continuous support.

In brief: a unique, quick and cost-effective application of our LCS-L system.

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.

No more costly inspections and maintenance for level crossings on main line Paris-Lille

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.

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.

14.000 units of edilon)(sedra Corkelast® EBS Embedded Blocks for Education City, Qatar

edilon)(sedra has played a pivotal role in the supply of more than 14.000 units of edilon)(sedra Corkelast® EBS Embedded Blocks for Education City people mover in Qatar. The units are installed in the summer of 2015 in the Depot, elevated track and shortly within the tunnel.

Education City people mover, is an 11.5 km catenary-free tramway which is being built to serve the Qatar Foundation for Education, Science & Community Development’s education and research campus west of Doha. Awarded in July 2012 to the Siemens Tram Consortium of Siemens AG, Siemens WLL Qatar and Habtoor Leighton Group.

Mark Fowler, Sales Manager Middle East at edilon)(sedra: “The decision to use the Corkelast® EBS units was made because of its high resistance to stray currents, an abso­lute requirement stipulated by Siemens Tram Consortium. In addition edilon)(sedra were able to mobilise their supply and delivery within record time, hence providing continuity of productivity within the track construction.”

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 separated 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 underpass 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.

Solutions in optimal track construction height for St. Gallen station, Switzerland

edilon)(sedra received its first contract from Appenzeller Bahn to install Corkelast® ERS (Embedded Rail System) for part of the tramtrain track in front of St. Gallen station, Switzerland.

The Trogener Bahn as operator of the tramtrain in the region of St. Gallen had problems with the construction height in front of the railway station, because of an existing underground car park. They took the decision to install Corkelast® ERS in this section because this system offers optimal construction height.

Another important factor why Appenzeller Bahn chose for Corkelast® ERS was the additional reduction of vibration in this historical and crowded station area.

The complete project construction company was the Swiss contractor WALO.
edilon)(sedra supported WALO with technical assistance during the installing and the pouring of edilon)(sedra Corkelast®.

HKL Helsinki choose edilon)(sedra ERS for new bridge in Helsinki

edilon)(sedra successfully installed 208 meters of  ERS-track on the new Pasila bridge in the city of Helsinki. The track installation in the Finnish capital took place in mid-July 2015 and is the first project for HKL (Helsinki City Transport) in which ERS (Embedded Rail System) is applied.

The ERS installation was done as a turnkey-job by edilon)(sedra Contracting, in good and close cooperation with HKL. The bridge is planned to be finished in September 2015.

The new bridge is built right next to the existing Pasila bridge. The two bridges will be connected, creating a new double tram track in the middle and so providing more space for the (separated) road traffic.

Important factors, why HKL have chosen for ERS, were the maximum stray current protection and the low building height. But the fact that ERS is virtually a maintenance free system, and thus providing maximum availability of the track and saving in the long term future financial outlay, which was also a key element in their decision.

HKL has planned the renewal of the old part of the bridge in 2016. And also for the new track on this part of the bridge ERS is their preferred solution.

French Tunnel de Montets: unique dual way solution

Railway tunnel ‘Tunnel de Montets’ located in the French Alps celebrates its first year of exploitation. This week, exactly one year ago the tunnel opened its doors after completing a full refurbishment with edilon)(sedra ERS (Embedded Rail System). Four seasons, including extreme cold and a winter with heavy snow falls,  later, the experiences and reactions in the local media are overwhelmingly positive.

Located in a mountain valley, the Tunnel des Montets has a double feature, unique in France and elsewhere: The tunnel  has been converted to a dual purpose railway tunnel which can also be used by cars and trucks when the mountain pass ‘Col des Montets’ is closed to traffic due to winter weather conditions.

The refurbishment with ERS was an important part of the modernisation of the Tunnel de Montets (line St. Gervais – Chamonix). The installed system not only improved the accessibility, safety and environment, it also offers (local) economic advantages because of the efficient use of the tunnel.
