One system crossing the boundariesCorkelast® ERS - Embedded Rail System for optimum integration into tunnel, station and bridge structures
How can you improve safety and accessibility in tunnels and stations? How can you accurately integrate a rail track
in a bridge design and save on installation time? These are only some of the questions that are central in the design
process of railway tracks, whether they are designed for tunnels, stations or bridges. The answers can be found in
the solutions for which edilon)(sedra received its recognition : technology for embedded rail fastening systems.
edilon)(sedra is an international manufacturer and supplier of rail fastening systems. The company cooperates in turnkey rail infra-
projects throughout Europe, Asia, Australia, North America and the Middle East. An important activity of the company is to provide
technical rail track solutions for tunnels, stations and bridges. The basis of these solutions is the edilon)(sedra ERS (Embedded
Rail System). This robust and proven ballast free system has flexible application options for both heavy and light rail.
Embedded Rail System (ERS)ERS has radically changed the concept of how rails can be supported. The use of a homogeneous continual elastic support
along the full length of the rail provides the required support, resilience and electrical insulation. Moreover it eliminates the logistical
problems and costs associated with ballast, sleepers, base plates, fasteners and their subsequent inspection and maintenance.
The system can be installed quickly and is adaptable to all rail profiles.
The main product in the ERS rail fastening system
results from enclosing and bonding the rails with
the 2-component edilon)(sedra Corkelast® in a
concrete or steel channel. This unique, long-life
material ensures that the rails have homogeneous
support throughout, with specifically determined
elasticity, in accordance with specified conditions.
Corkelast® is a polymer embedding compound
with a defined stiffness through the unique mixture
of filling material that depends on the product type.
Resilient ERS Strip controls the rail deflection for
ERS rail fastening systems, under the prevailing
loads.
These and many more features make edilon)(sedra
ERS perfectly applicable for heavy and light rail
tracks in tunnels, stations and on bridges.

Corkelast® ERS (vignole rail)
Optimal longitudinal performance ERS is fully compliant with EN 13481-5:2012 on longitudinal performance. Requirements on longitudinal rail restraint are important
criteria for safety in case of braking and acceleration of trains. The longitudinal rail restraint is much higher for edilon)(sedra ERS
than for most other mechanical rail fasting systems. The longitudinal rail restraint of ERS is tested indirectly, namely by means of
the longitudinal stiffness test. For 7 mm longitudinal rail displacement, the required force is usually 50kN per 0.6m ERS, which is 7
times more than the longitudinal rail restraint of most other mechanical rail fastenings.
ERS for tunnelsTunnel projects (new tunnels or refurbishment of old ballast tunnels) are often complex, time consuming and costly because of
the issues concerning the limited height of the tunnel, strict safety requirements, water drainage, the need to combine train/tram/
metro traffic with car traffic and the need to save installation and future maintenance costs.
edilon)(sedra ERS provides a solution for each of these issues. The system offers optimum reduction of tunnel construction height
and therefore is an ideal solution for tunnel projects that have to deal with strict installation requirements. Besides being robust
and durable, the system creates optimal accessibility for emergency vehicles. A very important consideration for contractors or
tunnel operators which have to deal with strict safety requirements!
edilon)(sedra ERS can operate in extreme climatological circumstances, from very hot to very cold or wet situations. ERS can be
installed to accommodate all kinds of gauges and rail profiles: both standard and non-standard gauges but also for example a
tunnel gauge of 1000 mm.

French Tunnel de Montets:unique dual way solutionRailway tunnel ‘Tunnel de Montets’ located in the European mountain area The Alps celebrates its first year
of exploitation. In July 2014 the tunnel opened its doors after completing a full refurbishment with edilon)
(sedra ERS Embedded Rail System. Four seasons later, including extreme cold and a winter with heavy
snow falls, 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 edilon)(sedra ERS Embedded Rail System was an important part of the modernization of the Tunnel
de Montets (line St. Gervais – Chamonix). The installed Embedded Rail System not only improved the accessibility, safety and
environment, it also offers (local) economic advantages because of the efficient use of the tunnel.

ERS for stationsExpansion and modernisation of railway stations influence the development of rail tracks.
edilon)(sedra can build on more than 40 years of experience in developing state-of-the-art rail tracks or tram, train, metro and high
speed train stations.
ERS provides optimal contribution to vibration attenuation in station buildings. An important aspect in cases of iconic buildings
and residential areas. Due to the Corkelast® material, the system has a high performance in electrical insulation. Furthermore the
flat surface of the ERS track allows easy & effective station cleaning, and very important: easy access for rescue services from
the platforms to the station tracks. The modern design of the system contributes to a perfect aesthetic integration into the station
building and railway platform. A very important aspect for architects!
Technical features of edilon)(sedra ERS for stations
• Free accessible escape routes for passengers
• Accessible for rescue and service vehicles
• Reduction of station construction height
• Optimal electrical insulation
• Short track possession times during installation
• Prefabricated solutions for a short installation time
Easy access for emergency road vehicles Prefabricated ERS slab track solution (logistics)

Renovation of tracks in Atocha HSL station, Madrid after more than 20 years in service
edilon)(sedra recently renovated part of the rail track in Platform 5 of railway station Madrid-Puerta de
Atocha in Spain. Since its construction in 1992 the ERS track (Embedded Rail System) had not required
any maintenance. The rails at the tight curved approach and straight platform tracks needed to be
renewed. The 1st phase of renovating 15 tracks started in June 2015 at Platform 5. The total track
renovation was completed in a short Sunday shift, without any nuisance for the public or timetable.
Virtually maintenance free systemThe old station ‘Estación de Atocha’ (now called ‘Estación de Madrid-Puerta de Atocha’) is one of the
most beautiful architectural complexes in Spain. The first high-speed line in Spain was built in 1992 by
edilon)(sedra and connected the cities of Seville and Madrid.
Only after more than 20 years in service did ADIF have to renew rails, which proves the extended lifetime
which Corkelast® ERS is offering to rails and its maintenance-free feature.

art rail track solution for bridges based on ERS (Embedded Rail System), with an integrated guard rail structure.
ERS designs for bridges with integrated guard rail:
• Steel channels on a steel bridge
• Steel channels on a concrete bridge (deck)
• Steel channels integrated in a steel bridge (deck), including Silent Bridge (full integration)
• Concrete channels integrated in a concrete bridge (deck)
The unique technical features of edilon)(sedra ERS bridge application starts with the accurate integration in bridge designs, the
free accessible escape routes and the short track possession times. Moreover this system has an aesthetic design without
interfering beams - an important feature in case of monumental bridges.
