ElanRail, the Nantes-based company behind the dynamic wildlife collision prevention system deployed by SNCF Réseau

Every year, 5,000 trains are disrupted by collisions with wildlife. ElanRail has developed a dynamic wildlife collision prevention system, deployed by SNCF Réseau.

La SNCF les présente comme « ses bêtes noires » : les collisions avec la faune sauvage et plus particulièrement les sangliers. En 2024, plus de 5 000 trains ont été retardés ou supprimés en France à la suite de heurts avec des sangliers, des chevreuils et d’autres espèces. Pour répondre à cet enjeu, ElanRail a développé avec SNCF Réseau le seul dispositif d’alerte dynamique pour préserver la régularité ferroviaire. Issue de l’expertise de l’entreprise nantaise ElanCité, un des leaders mondiaux de la sécurisation des axes routiers via notamment ses radars pédagogiques, ElanRail déploie progressivement sa solution sur tout le territoire. Objectif : devenir la nouvelle norme en matière de prévention des collisions entre trains et animaux sauvages.

5,000 trains affected each year by collisions with animals

Collisions with wildlife are now a major black spot in rail transport, with serious consequences for the operation of lines. According to data published by the SNCF Group, 2,562 collisions were recorded in 2024 nationwide, an increase of +76 % between 2020 and 2024.

This continued progression of wildlife collisions directly affects the regularity of trains and the overall reliability of the network, with an average cost per collision estimated at €100,000.

From securing road to securing rail networks

ElanRail is the sister company of ElanCité. In 20 years, this Nantes-based company has established itself as one of the world leaders in road infrastructure safety thanks to intelligent devices such as radar speed signs and speed control traffic lights. Recognised for its sustainable performance, ElanCité was distinguished as a “2026 Long-Term Growth Champion” in the Les Echos – Statista barometer, which highlights high-growth independent French companies.

ElanCité has developed in-depth expertise in innovation and proven French industrial production capabilities. This operational excellence has enabled us to deploy over 50,000 products in 45 countries.

Building on its experience, ElanCité has given rise to ElanRail to reduce collisions between trains and wild animals. ElanRail has thus leveraged its expertise in detection, connectivity, and autonomous, solar-powered systems to create Blue Sentinel, the dynamic alert and prevention system for train-wildlife collisions in a railway environment.

A l’origine, une collaboration avec SNCF Réseau Pays de la Loire a permis de développer, en un temps record, cette solution innovante de sécurisation des infrastructures adaptée au secteur ferroviaire et répondant aux besoins terrain. Testée et fiabilisée pour répondre aux contraintes de SNCF Réseau, la première phase de test de Blue Sentinel a duré 18 mois de juillet 2024 à décembre 2025. Résultat : une réduction de 90 % des collisions avec la grande faune (sangliers, cerfs, chevreuils, etc.) en comparant avec la période précédente.

Blue Sentinel is currently installed in three French regions, securing six railway sites identified as being particularly exposed to animal crossings. This initial step marks the beginning of a large-scale rollout, both in France and internationally, of this unique market solution.

Blue Sentinel, innovation for railway service reliability

Blue Sentinel is based on an intelligent system of autonomous beacons installed in accident-prone zones spanning several kilometres. They detect the arrival of a train and, before it passes, trigger deterrent light and sound signals intended to alert wildlife and keep it away from the railway tracks.

Avec Blue Sentinel, ElanRail répond concrètement aux besoins du secteur, des usagers et contribue à la protection de l’environnement en offrant :

  • Increased punctuality and quality of service for rail users by reducing train delays and cancellations.
  • The promise of peaceful coexistence between wildlife and trains.
  • Cost control for railway network managers with optimised investment and a reduction in collision-related costs.

Nous sommes fiers d’avoir la solution pour limiter le retard ou la suppression d’un très grand nombre de trains en France et dans le monde. Pour relever ce défi, nous pouvons compter sur les forces d’ElanCité développées depuis 20 ans : culture de l’innovation, agilité et capacité de production industrielle. Nous sommes au début d’une belle aventure qui allie innovation utile et impact réel.
