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.
Tested and approved to the standards that matter for UK rolling stock — including BS EN 45545 fire safety requirements.
Where It Goes
Fogtec delivers a complete onboard fire suppression capability — protecting every high-risk area of a modern passenger vehicle, from traction packs and HVAC to driver cabs and passenger saloons.
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.
