Blue Sentinel:
low-profile,
high-impact
A self-powered alert system that keeps traffic flowing, protects wildlife and cuts disruption costs
Designed and manufactured in France, built for European networks
Blue Sentinel is simple to install and requires no specialist civil-engineering work. It consists of two main units:
- A detection beacon, which can either be installed directly on the ground via its concrete base or ground-mounted on the catenary support.
- An alert beacon, planted in the ground.
Every Blue Sentinel unit is designed and manufactured in France, with ISO 9001-certified suppliers and end-to-end quality controls, so every installation performs to the same high standard.
Four key benefits
Four strengths that make Blue Sentinel a key ally for securing the rail network
while preserving the surrounding ecosystem.
Robust
- Safe, proven train-detection technology.
- Low-visibility alert-beacon casings.
- Materials built for harsh environments and designed to deter theft.
- Responsive, readily available technical support.
Reliable service
- Smoother, more regular and uninterrupted traffic
- Cost-effective from year one.
- No disruption for train drivers.
- An ecological and economical alternative to conventional solutions.
Respectful of wildlife
- Guaranteed ecological continuity: an ethical, biodiversity-friendly approach.
- No disturbance to local wildlife corridors, the system activates only as a train passes, with low-intensity deterrence.
- Sound-alert levels configurable independently for each beacon.
- A range of stimuli that keep wildlife responsive and prevent habituation.
Simple to deploy
- A connected, energy-autonomous beacon network: up to 200 train passages/day as standard, on solar power.
- Simple installation: no civil works, no cabling, whatever the terrain: zero impact on rail infrastructure.
- Adaptable to all environments: forest, mountain, wetlands, open fields.
- Easy, intuitive supervision via a dedicated web interface and mobile app.
Blue Sentinel, the future of railway safety
"As wildlife populations grow and rail networks expand, the need for effective, non-invasive protection has never been greater. Blue Sentinel is built for that challenge."

Comment Blue Sentinel préserve-t-il le bien-être de la faune sauvage ?
Blue Sentinel alerte les animaux, il ne les effraie pas. Les signaux visuels et sonores sont précisément calibrés pour inciter les animaux à s'écarter des voies à l'approche d'un train, pas pour les perturber. Le niveau sonore est volontairement faible (sans commune mesure avec les effaroucheurs utilisés en milieu agricole). En dehors des passages de trains, le dispositif est inactif : la faune traverse librement, où et quand elle le souhaite. Les corridors naturels sont ainsi préservés.
Comment Blue Sentinel s'intègre-t-il dans son environnement, y compris à proximité des riverains ?
Blue Sentinel only activates when a train passes. The sound level is comparable to that of a conversation between adults and it can be adjusted beacon by beacon, depending on the specific characteristics of each installation zone.
Quels sont les avantages de Blue Sentinel par rapport au grillage des voies ?
Sur les corridors écologiques, Blue Sentinel constitue une alternative particulièrement pertinente en préservant la continuité naturelle des déplacements de la faune, là où un grillage crée une barrière physique. Il présente également des avantages économiques sur le coût global : autonome en énergie, il ne nécessite pas d'entretien particulier, contrairement au grillage qui implique une maintenance régulière de la végétation..
Comment est née la solution Blue Sentinel ?
Blue Sentinel is an innovation designed and developed by ElanRail in partnership with SNCF Réseau Pays de la Loire. This collaboration made it possible to combine field expertise and technological know-how to create a solution with no impact on railway infrastructure. Following an 18-month pilot phase conducted jointly with SNCF Réseau, ElanRail now handles the deployment, installation, and operation of the solution across several sites in France, with ambitions to expand at a European scale.
Quels sont les atouts économiques de Blue Sentinel ?
Blue Sentinel targets collision hotspots where risks are highest, over just a few kilometres, in order to optimise investment. Solar-powered, requiring no significant maintenance, and installed lineside with no civil works required, the system offers a controlled operating cost. Its remote configuration and monitoring via a secure web platform also streamlines maintenance operations.
