Red Line light rail project, Tel Aviv

Playing a role in different track related project disciplines, from the technical advice and track design to the supply and installation of track systems. This is when we are at our best! Our ultimate goal: the delivery of sustainable track systems.

Take for example the current Red Line light rail project in Tel Aviv, Israel. Initially, edilon)(sedra Iberica advised the infrastructure consultants Ineco (Spain) and Chinese contractors CRTG-EEB Red Line Systems, L.P. with track and compliance related aspects for the tender specifications. This cooperation led to the implementation of a series of interesting project solutions.

To ensure perfect electrical insulation of the track at the Kiryat Aryeh light rail depot, the Corkelast® Embedded Rail System was selected and installed, to meet the demanding requirements of the tender specification. After this positive experience, a sustainable watertight rail joint solution to seal off the fastening of the Red Line track was provided. Also, environmental friendly Jointelast STP was provided as durable sealant of the floating slab track joints. This sealant can handle movements of up to 2 mm.

To improve the electrical isolation properties of the standard rail fastening, the rail coating solution Editack N was offered for 24 km of light rail track. All in compliance with strict requirements of the local authorities on electrical insulation. Last but not least, our high-performance Corkelast® ERS was selected as part of the rail track construction for blast protective tunnel doors. This is what we’re all about: playing a versatile role as solution providers in technically challenging rail track projects!

The Red Line will connect two cities of the Tel Aviv Metropolitan Area: Petah Tikva and Bat Yam. The line will be 24 km long and include 33 stops. The city authorities plan to extend the network with three new lines. The Red Line project was awarded in December 2006 to the Metropolitan Transportation Solution (MTS). The operational date is planned for the end of 2021.






New iconic Kazungula railway bridge nearing completion!

In near future, travelling between Zambia and Botswana will get easier, smoother and faster, when the new Kazungula road/railway bridge, currently in completion across the waters of the Zambezi, is commissioned for public use.

When completed, the bridge will be connected to the Mosetse-Kazungula Railway. The 923 m long masterpiece will link the town of Kazungula in Zambia with Botswana. At this point, four countries – Botswana, Namibia, Zambia and Zimbabwe – meet.

With the support of the AfDB African Development Bank, the Kazungula bridge project will open up economic opportunities across the region.

edilon)(sedra are proud to be part of this iconic structure, supplying 1.500 m of Corkelast® ERS Embedded Rail System to client IkusasaRail, providing a virtually maintenance free track system for years to come.

In this video the benefits of the bridge are explained:



State-of-the-art track system solution for Metro Line 2 Warsaw

Did you know that we are actively involved in one of the largest metro projects in Eastern Europe? We supplied a state-of-the-art track system solution for Line 2 of the Warsaw metro network in Poland, based on Corkelast® EBS blocks and Trackelast® mats, offering optimal noise & vibration control especially for critical areas in the city.

No less than 27 km of edilon)(sedra Corkelast® EBS track was installed, including Trackelast® noise & vibration mats, EBS bearers for turnouts, crossroads and double track connections and 520 m of Corkelast® ERS (Embedded Rail System) track. Part of this project are the three newly built stations: Szwedzka,Targówek Mieszkaniowy and Trocka. In the first week of operation of the Targówek extension, 900.000 people used Line 2 of the Warsaw Metro! Further network extensions are planned for the near future.

The metro project can be divided into three phases. For each phase you can check the related colored lines in the illustration below.

Red line: this is the central section of the metro network from Rondo Daszyńskiego to Dworzec Wileński. The line has been in operation since 2015.
Dark blue line: this marks the first east extension to Targówek which was officially opened on the 15th of September 2019.
Green line: this is the first extension to the Wola department in the west section of the metro network. Track works are finished, this extension will be opened in 2020.

Newhaven: level crossing replacement in high risk rail-road area

edilon)(sedra have been awarded the contract to supply and replace an existing level crossing with a 48 m twin track level crossing at the docks in Newhaven, UK. The location of the crossing is considered a high risk rail-road area.

The secondary line level crossing in Newhaven docks is used by DMU passenger and freight aggregate traffic. The crossing is the only access to the large bulk handling area of the town’s docks. These docks have a very high volume of bulk aggregate materials arriving by ship with the majority leaving via the level crossing. The combination of the heavy loads, poor soil, poor drainage and nonperpendicular angle of the crossing to the road causes the road profile to deform into a high risk condition for road users. Complaints to the council on safety issues are a common occurrence.

The current level crossing is based on rubber panels and the substructure below is saturated marine alluvium with no identifiable drainage. The crossing is approximately 4 years old and unable to maintain its road profile. The angle of the level crossing is non-perpendicular to the road crossing. This generates damaging oscillating forces when the multiple axle road vehicles traverse the rubber units. During discussions between track owner NWR Sussex and edilon)(sedra it was agreed that the only viable, low risk and cost effective solution was to apply the pre-cast level crossing system Corkelast® LCS-350. The system is a development variation of the existing Harmelen crossing which is already approved by NWR.

In this harsh environment, the proven advantages of Corkelast® LCS-350 were a defining factor in NWR opting for the system:

  • Poor ground conditions – Able to spread load over a large surface area decreasing the ground pressure to a minimum.
  • Fluid ground conditions – As the ballasted track has been removed and the system no longer requires tamping, the ground is, in all essence, sealed under the slabs creating a stable integrated platform which reduces the possibility of water “pumping”.
  • Damaging forces from road traffic – The use of larger heavy slabs makes the system more stable so the forces are dissipated before the effect can cause any damage.
  • Water causing corrosion – The rail is chemically bonded to the concrete and therefore protected against corrosion. No more steel fastenings are used that would suffer from accelerated corrosion due to the ever present water.
  • The rail is continually supported, which reduces the peak loading associated with a traditional sleeper track design during both train and road traffic.
  • A reduced risk to cyclists and pedestrians due to the smooth integration of the slabs with the road surface.
  • Asset life of 40 years and minimal maintenance interventions.

New series of level crossings for the Danish port of Fredericia

Durable solution for greater freight capacity, improved transport efficiency and cleaner air

After the installation of a series of edilon)(sedra Corkelast® LCS level crossings in June 2019 in the port of Fredericia, our company installed another level crossing in September 2019. This 165 m crossing, with a 150 m radius curve, is the heavy duty “CT” version of Corkelast® LCS-350.

We were responsible for the slab design, installation of the slabs, planning and application of the Corkelast® LCS. The new crossings will result in greater freight capacity, improved transport efficiency and cleaner air. Freight can be switched between road, rail and sea more easily and efficiently.

“Fredericia Havn” opted for Corkelast® LCS because of good experiences with this level crossing system in the past. During the installation process the harbour remained in operation 24/7.
