Safety and performance

Safety is the top priority for AGIFI members. Maintenance teams work 24/7 to guarantee the safety of the railway infrastructure.

Almost 1,000 employees work every day to improve the safety, reliability, and consistency of the networks. Innovation also plays an important role, with smart infrastructure monitoring systems and new approaches to predictive maintenance that improve passenger safety and operational performance.

The companies that maintain these lines have developed continuous monitoring tools that are specific to the line they oversee and do not exist on the rest of the network. Each maintenance company has its own supervision centre.

Each maintenance company has its own supervision centre. 
OPERE, which maintains the BPL HSL, uses the “Centre Opérationnel BPL” (COBPL) while MESEA set up “Hypervision MESEA” for the SEA Tours-Bordeaux HSL. These centres serve as veritable control towers for the lines. They monitor all the systems required to operate the high-speed trains, which does not occur on the rest of the network.

As part of their agreements, AGIFI members are committed to offering particularly high levels of performance. To do so, they have developed specific expertise and tools.

In particular, they are committed to monitoring their infrastructure to provide effective corrective maintenance and expand the use of predictive maintenance, which allows them to intervene as soon as a problem is detected to significantly reduce the impact on traffic.

AGIFI members have developed a strategy based in large part on predictive maintenance to guarantee the operational performance of their infrastructure and the long-term economic efficiency of the projects.

To that end, maintenance is conducted as early as possible and future problems are anticipated. 

Innovation to improve maintenance

Rail-road vehicles

OPERE and MESEA use these innovative modular vehicles on both railways and roads to maintain the tracks and overhead lines. They replace draisines and can get on and off the rails near the worksite, thereby limiting congestion on the line.

AGIFI members’ innovations go beyond technological features. They sometimes lead to changes in the railway industry’s methods and habits. For example, the optimisation of daily safety checks on the SEA HSL: every morning, instead of using a TGV (high-speed train) to open the line and detect possible problems on the track (as with the rest of the network), MESA-designed locomotives packed with sensors check the condition of the tracks. This approach is more economical and probably just as effective.

AGIFI members are constantly working to improve our performance with a single objective: reduce the number of incidents to provide our customers with the best traffic conditions to ensure a high degree of regularity, reliability, availability, and comfort on the lines.

Vincent Rambeaud, Performance Manager in LISEA’s Operations Department

Hervé Le Caignec graduated from École Spéciale des Travaux Publics (TP86) and started his career building and maintaining road infrastructure.

He then oversaw the development and operation of major infrastructure through Public-Private Partnerships (PPP) both in France and abroad. He spent 14 years at the VINCI Group, 4 years at SNCF, and 10 years at the Caisse des Dépôts Group. In March 2017, he was named Chairman of LISEA, the concession holder for the Tours-Bordeaux high-speed line.

A graduate of École Nationale des Ponts et Chaussées, Gilles managed the Île-de-France regional branch for Egis Aménagement (transport and mobility engineering, urban development, etc.). He then served as Managing Director of the European Economic Interest Grouping that manages and operates the Mont Blanc Tunnel for ATMB and the Italian Mont Blanc Tunnel Company (SITMB).

He became the new Managing Director of Oc’Via on 1 May 2019.
