Just-in-time level crossing solution for London Underground

edilon)(sedra started supplying a just-in-time level crossing solution for London Underground. The edilon)(sedra Corkelast® LCS-350 solution, which will be installed in the Ruislip depot, saves London Underground  money on storage and handling.

In the first week of February 2018 a Factory Acceptance Test (FAT) was carried out by London Underground, which involved a full dimensional check to ensure the level crossing slabs were identical to submitted and approved technical design documents.  The FAT was given a pass by London Underground.

The slab manufacturing plant is in Cornwall, United Kingdom, where under the guidance of edilon)(sedra Application Engineering and edilon)(sedra Contracting the slabs are manufactured.

The installation of the 53 m level crossing (18 x 3 m slabs / curve radius: 121 m) will be carried out during the weekend of 16, 17 and 18 February 2018.

Video release – Moerdijk bridge rail replacement

What does an edilon)(sedra Corkelast® ERS (Embedded Rail System) rail replacement on a large and heavy duty train bridge look like nowadays? How can a smooth workflow be accomplished on a challenging project with a constricted working environment, stringent waste management practices, and a limited working schedule? What state-of-the-art solutions are used to limit vibrations […]

Exhilarating exhibition TRAKO, Poland

TRAKO, an exhilarating exhibition for edilon)(sedra in good cooperation with its partner Fehlings Krug Polska. A conclusion  drawn at the end of the exhibition, which took place from the 26th till the 29th of September 2017 in Gdanks, Poland.

The exhibition provided us opportunities to demonstrate edilon)(sedra´s worldwide activities in the railway sector and to strengthen existing business contacts in Poland and Eastern Europe. We were pleasantly surprised with the sincere interest of visitors in our company’s latest rail track innovations.

Combi terminal New Arken, Gothenburg

In the Swedish city of Gothenburg a new combi terminal ‘New Arken’ is being realised. For track 903, main contractor NCC awarded edilon)(sedra the assignment to realise 622.5 meters of Corkelast® HSTS (Heavy rail Slab Track System), a combination of prefabricated concrete slabs, type ‘New Arken’ and the edilon)(sedra Corkelast® ERS (Embedded Rail System).

In addition edilon)(sedra will realise four 18 meter level crossings in Tracks 911a/b and Tracks 912a/b near the entrance of the terminal. These level crossings (situated in curves of R=150m and R=200m) will be of edilon)(sedra type LCS-L3. The edilon)(sedra part of the project will be realised in September 2017. The turnkey project, including slab design, implementation of the slabs and ERS application, is expected to take around 3 weeks. NCC is working for the Port of Gothenburg, the owner of the ‘New Arken kombiterminal’. When the terminal is finished it will be operated by Sandahlsbolagen.

The New Arken project is comparable with our recent container terminal project ‘TCT Venlo’ in the Netherlands. In the summer of 2015 we supplied 1.200 meters of Corkelast® edilon)(sedra HSTS for this terminal.


Replacement blocks Hemtunnel Zaandam, The Netherlands

On the 26th of April and the 15th of July edilon)(sedra started the replacement of the block based track system in the tunnel ‘Hemtunnel’ in Zaandam by the state-of-the-art Corkelast® Embedded Block System (EBS), after being almost 35 years in service.

The first 345 blocks from a total of 1.560 blocks were replaced by EBS type 54-E1 in only two short night shifts. edilon)(sedra is responsible for the engineering and production of the blocks as well as the on-site installation, including the delivery of tools and equipment.

Increasingly, EBS is being chosen as the preferred track system for replacing traditional block-based systems in tunnels. The Corkelast® based system offers an easy and flexible installation and therefore a very short out-of-service period. Furthermore EBS is applied because of its durable characteristics. The system ensures a strong reduction of dynamic loads and vibrations and excellent electrical insulation which is important in areas with moisture and/or risk for corrosion.

In the next period the remaining 1.215 blocks will be replaced, after which the Hemtunnel track will ready for many years of safe and reliable rail transport.

Sincere interest in the manual ‘ERS on Bridges’ during IAF Münster

edilon)(sedra looks back on an exciting IAF exhibition in Münster, Germany. Rail experts from all over the world were very interested in examining our company’s latest rail track innovations.

Special point of interest was the launch of our ‘Complete Manual Embedded Rail Systems’.

This 40 page handbook builds the conduit between the diversity of challenges faced when designing railway bridges and the solutions that ERS Embedded Rail System provides in practice. The manual discusses different types of bridges and bridge covers, based on the compatibility of ERS, as well as solutions for transition zones, integration of compensation welds or devices, as well as glue seals, signal and detection currents and draining. Aspects such as technical implementation, operation, finances and lifespan are also discussed in detail.

Because of the frequent interest shown in this manual, we’ve decided to offer it as free PDF download option on our website:
www.edilonsedra.com/manual (English version)
www.edilonsedra.com/handbuch (German version)








We are looking forward to your positive feedback and we hope to see you again during the next edition of IAF!

SDS – In street tracks designed for optimal durability
Railway transportation is an indispensable part of modern society, which has to meet environmental regulations for noise and vibrations. edilon)(sedra SDS (Sound Damping System) fits perfectly into these requirements. edilon)(sedra as inventors of filler block systems, developed this cost effective track form for tramway applications.

In order to increase the isolation property of the filler block systems and rail encapsulation systems, the effective joint sealant material edilon)(sedra Jointelast STP can be combined. Jointelast STP is a highly elastic polymer-based sealant that is ideal for sealing joints in the areas of road and track construction as it adheres to steel, asphalt and concrete and it can absorb dynamic and static loads. For more information about edilon)(sedra SDS, or edilon)(sedra Jointelast STP and its diverse applications like the 7.5 km Luas Cross City tram line in Dublin, Ireland and the 80 km Education City people mover in Doha, Qatar please visit our stand S/500!

EBS – Future-proof ballastless rail system for metro Bucharest
edilon)(sedra Corkelast® EBS-MS (Embedded Block System) was chosen by Metrorex (the Bucharest Metro Authority) for their new Metro Line 5 as it provides a watertight system with optimal electrical isolation and requires virtually no maintenance. The complete system design, switch bearers and guiderail blocks were performed by edilon)(sedra Application Engineering in close co-operation with the client. A thorough study on noise and vibration effects with Slab Track Mats has been performed by the German consultant company I.B.U. in Essen, specialized in the field of noise and vibration effects.

Curious about the impact? Please visit our stand S/500! We would be delighted to inform you about our Corkelast® EBS system and the Metrorex project.

SIFER 2017: Firm foothold for Corkelast® ERS in France

The exhibition SIFER 2017 offered a perfect opportunity to strengthen business contacts and to celebrate our firm foothold of the Corkelast® ERS rail fastening solution in the French market. This conclusion was drawn at the end of the exhibition, which took place from 21 to 23 March in Lille, France.                                 

One of the highlights was the official approval of SNCF for the edilon)(sedra Corkelast® ERS (Embedded Rail System) for heavy rail and high speed traffic classes which was confirmed just before the exhibition.  In presence of SNCF delegates this important achievement was celebrated on Wednesday the 22nd with a glass of champagne at the exhibition stand.

Moreover, the exhibition provided opportunities to strengthen existing business contacts in France and Magreb but also generated many new contacts, attracted by the opportunities the SNCF homologation offers and the Application Engineering service that comes with it.

We are looking forward to the next edition of SIFER.
