Clayton Engineering

When Clayton Engineering won the contract to supply locomotives to be used on the reconstruction of the Paris sewage system, it turned to Nobel Fire Systems to provide fire safety on board its fleet of below ground locomotives.

The locomotives are designed to haul loads underground and are relatively complex vehicles working in demanding environments. A fire suppression system was needed that would fully protect the main control panels mounted in the drivers cab and the locomotives cooling system.

All of that meant Nobel’s engineers had to provide a system that could be fitted into compact spaces within the vehicles and be capable of providing effective and reliable fire suppression under their arduous operating conditions. Working in the labyrinth of sewers below the French capital had its own special safety requirements with the consequence of fire breaking out underground being enormous.

The locomotives main control panel was fitted with Nobel’s condensed aerosol technology suppressant, known as Stat-X.  This system is extremely competitive and highly effective particularly in situations where space is at a premium. It’s environmentally friendly and allowed for easy, cost-effective installations within the cab area control panel.

To protect the locomotives critical cooling system, Nobel fitted a dry chemical powder fire extinguisher system. The system protected against foreign bodies potentially setting fire to the cooling coils.

Both systems combined provide comprehensive protection to the key risk areas within the locomotives and the project is another example of the diversity of application Nobel is capable of solving.
