At the start of 2019 the old booted sleeper track of Metro line 2 of Metro Valencia needed to be replaced. The booted blocks were completely worn out. Tie-bars had to be removed due to corrosion and electrical isolation problems. The track no longer functioned according to the system requirements of today’s regulations.
One of the most serious problems for Metro Valencia is the groundwater level. The water has 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 3,5 hours. Implications for the environment and stakeholders were taken into careful consideration. edilon)(sedra prepared the renewal works, in partnership with the Valencian public railway company FGV and the contractor Comsa. The new Corkelast® EBS-RF system, was installed by a small team of people and number of 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!
