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.

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.

The port of Fredericia project is comparable to our recent container terminal projects “TCT Venlo” in the Netherlands and “New Arken Kombiterminal” in Gothenburg, Sweden.
