State-of-the-art track system solution, based on EBS blocks and Trackelast® mats, offering optimal noise & vibration control especially for the critical city areas.
In 2022, the newly built western section of MetroLine2 in Warsaw has been taken into operation, including two new stations Bemowo and Ulrychów. Mid-2022 the official opening took place at the Bemowo station, by Mayor of Warsaw Rafał Trzaskowski and by EU Commissioner Elisa Ferreira.
edilon)(sedra are proud to have contributed to this project, supporting the contractor Gülermak. edilon)(sedra supplied a state-of-the-art track system solution, based on EBS blocks and Trackelast® mats, offering optimal noise & vibration control especially for the critical city areas.
For project Line 2, more than 30 km of edilon)(sedra EBS track has been installed, including EBS crossroads and double track connections and 520 m of Corkelast® ERS (Embedded Rail System) track. The Polish Railways PKP have implemented EBS for their turnout bearers too. Based on the detailed switch design edilon)(sedra Application & Engineering designed the most optimum bearer configuration to provide the right support for the high impact loads in these locations.
The chosen EBS system is well known for its excellent reduction of dynamic loads, low vibrations emissions and its optimal electrical insulation. A very important aspect in tunnels which are often damp and wet.

An achievement to be proud of! Recently, our RetroFit system solution EBS-RF was installed for Metro Valencia (FGV) at Plaça d’Espanya during a replacement operation, where old booted bi-block sleepers were renewed in a few short overnight possessions.
Traffic congestion, combined with wet and humid tunnel conditions often lead to damaged and worn out booted (bi-)block systems. Increased rail wear, track geometry problems, broken and corroded tie-bars, concrete damage, track instability, electrical isolation and signalling problems are often found in these track locations.
Tracks often suffer from emergency service interruptions and nightly visual inspection. Taking tracks out of operation is virtually impossible as this involves huge costs. A lot of issues to deal with!
The solution lies in a new system of the edilon)(sedra EBS family: EBS-RF. The basis of this innovative RetroFit track system consists of a durable block with integrated elastic tray, both prefabricated under controlled conditions. The system can be adapted to any size to fit the existing pocket after removal of the old booted blocks. EBS-RF is supplied as complete unit, ready for immediate application and quick installation: a replacement period of just a few hours is extremely critical to ensure the continuation of operational traffic the next day.
In Valencia, Spain, the Valencian public railway company FGV required the old booted block tracks of Metro Valencia to be replaced in a short period of time.
One of the most serious problems for Metro Valencia was the groundwater level. The water had caused severe corrosion on the rails, on the fastening systems and on other elements of the track.
edilon)(sedra Application Engineering was consulted at the initial stage of the replacement project for technical advice and to analyse the existing track and concrete structure. Rail, track conditions and dimensions were carefully checked.
A renewal plan was created fitting the demands on quality, noise, vibration and possession times. To keep the trains running smoothly during the day, track maintenance on this metro line was implemented in a few short night shifts of only 4 hours. Implications for the environment and stakeholders were taken in to careful consideration.
edilon)(sedra prepared the renewal works, in partnership with FGV and the contractor Comsa. The new EBS-RF system, was installed by a small team of people and tools, under close supervision.
The completed installation was carefully inspected, resulting in a watertight, electrically insulated and low vibration metro track, ready for transportation of tens of thousands of passengers a day!
