The Tours–Bordeaux line reported service regularity of 96% – 99% taking into account only incidents attributable to the concession company.
MESEA have developed the SEACloud platform, which harnesses artificial intelligence to automate processing of operational data and thereby optimise predictive maintenance. New features are added regularly to the platform.
On the environmental front, LISEA implemented offsetting measures, from the design phase, spanning 3,800 hectares spread over 300 sites along the line to ensure no net loss of biodiversity, and will continue to manage the programme until 2061. The conference held in March 2024 by the environmental observatory for the SEA high-speed line was an opportunity to assess and monitor actions, along with non-profit groups advocating for the protection of nature, scientific experts and government representatives. LISEA and MESEA are also active in environmental and social causes through the Fonds SEA pour la Transition des Territoires, which supported 26 eco-agriculture projects in the regions served by the line in 2024.

Martinique BRT system
Through the company Caraibus and under a 22-year partnership, VINCI Railways built and now maintains part of the infrastructure for the reserved lane public transport system in Martinique. The 14 km rapid transport (BRT) service connects Fort-de-France to Le Lamentin. The infrastructure, now firmly rooted in users’ everyday practices, helps relieve road congestion in the island’s main economic centre.
GSM-Rail network
2024 was the last full year of execution of the 15-year partnership contract between the VINCI Railways subsidiary Synerail and SNCF Réseau to deploy, operate and maintain GSM-Rail. This global system for mobile communications between drivers and signallers is crucial to rail safety in France. Synerail and SNCF teams have prepared for the transfer of the network which covers almost 16,500 km of track and 80% of rail traffic in France to the public operator on 1 April 2025.
