Rolling Stock · Onboard Fire Protection
Watermist fire suppression engineered for trains, trams and rolling stock, delivered in the UK by Photuris with the world leader in rail watermist.
Onboard Specialists
Passenger vehicles demand a fire suppression technology that controls fire fast, uses a fraction of the water of conventional sprinklers, and works safely around people and electronics. That's why the world's leading rolling stock operators rely on Fogtec watermist, and why Photuris delivers it across the UK fleet.
Technology Partner
Rolling Stock Watermist
Fogtec watermist systems are installed on tens of thousands of vehicles worldwide, from metro trains to intercity fleets. Photuris is Fogtec's UK rolling stock partner, bringing that technology to British trains, trams and light rail.
Watermist uses a fraction of the water of conventional sprinklers, reducing weight, damage and downtime after any activation.
Ultra-fine microdroplets absorb heat and displace oxygen in three dimensions, suppressing fires that conventional systems struggle to reach.
High-pressure operation between 50 and 200 bar delivers the optimum droplet spectrum for onboard suppression—Class I water mist per NFPA 750.
Fogtec water mist systems are designed for rail applications and support compliance with EN 45545 fire safety requirements when integrated into rolling stock systems.
Where It Goes
Fogtec delivers a complete onboard fire suppression capability, protecting every high-risk area of a modern passenger vehicle: traction packs, HVAC, driver cabs and passenger saloons. High-pressure operation above 60 bar atomises water into microdroplets that cool, smother and scrub smoke at a fraction of the water damage of any conventional system.
Compliance
BS EN 45545 sets the bar for fire safety on UK rolling stock, from material classification through detection to suppression. It's not a tick-box, it's a design philosophy, and it shapes every decision on a modern vehicle.
Our engineers work to the relevant hazard levels and operation categories from the start, whether we're fitting out new-builds, delivering mid-life refurbishment or retrofitting Fogtec to legacy fleets.
We hold the accreditations to deliver: RISQS-verified, CIRAS members, and Sentinel-sponsored engineers for trackside and depot work.
Who We Work With
New-build fit-out, mid-life refurbishment and ongoing fleet maintenance: we partner with the organisations keeping British rolling stock moving.
Our Approach
We work with rolling stock operators, lessors and refurbishment contractors at every stage, from vehicle specification to final withdrawal.
