LISEA, subsidiary of VINCI Railways, renewed its safety accreditation to manage the South Europe Atlantic High-Speed Rail Line

April 6, 2022

Initially obtained in 2017, this accreditation was awarded after the EPSF approved the upgrade to the Safety Management System (SMS) and certifies LISEA’s ability to comply with safety regulations and control the risks involved in designing, building, maintaining, upgrading and operating the SEA HSL, the second busiest high-speed rail line in France.

This demonstration of trust, which is also represents an achievement for MESEA (the VINCI Railways subsidiary tasked with the maintenance of the SEA HSL and a VINCI Concessions Centres of Excellence for Innovation in railways), reflects the suitability of the operational organisation designed and resources allocated by VINCI Railways, which guarantee the highest safety standards in terms of rail traffic, infrastructure availability and longevity of the facilities.


This renewal also confirms the excellent operational results achieved in 2021:

  • Nearly 5.5 million kilometres travelled (26 million since the line was commissioned)
  • 100% of “high” priority operations (safety critical) were completed by MESEA within the timescales set out in regulations, in accordance with EPSF requirements
  • 0 serious accidents


Valérie Vesque-Jeancard, Chair of VINCI Railways, said, “This renewal, confirmed just a few months after MESEA obtained its Quality, Environment, Health and Safety certification, represents another accomplishment for our teams, especially the people from LISEA and MESEA, who endeavour day in, day out, to guarantee the highest safety and performance standards, in accordance with the requirements of the concession grantor, SNCF Réseau.”
