Fire fighting system, rail vehicle with fire fighting system and method for operating a fire fighting system

Fire fighting system comprising:

• a first feed platform arranged for feeding an extinguishing fluid to a piping system having extinguishing nozzles, including:
• a first sub-system with
• a first extinguishing fluid reservoir,
• at least two first propellant gas reservoirs, and
• a first control circuit,
• wherein one first propellant gas reservoir of the at least two first propellant gas reservoirs being pneumatically coupled to a valve of the first extinguishing fluid reservoir and the one first propellant gas reservoir of the at least two first propellant gas reservoirs can be pneumatically activated via an outlet of a second propellant gas reservoir of the at least two first propellant gas reservoirs;
• a second sub-system with
• a second extinguishing fluid reservoir,
• at least two second propellant gas reservoirs, and
• a second control circuit,
• wherein one second propellant gas reservoir of the at least two second propellant gas reservoirs is pneumatically coupled to a valve of the second extinguishing fluid reservoir and the one second propellant gas reservoir of the at least two second propellant gas reservoirs can be pneumatically activated via an outlet of a first propellant gas reservoir of the at least two second propellant gas reservoirs;
• wherein
• the first control circuit is operatively connected to the one first propellant gas reservoir of the at least two first propellant gas reservoirs of the first sub-system and to the one second propellant gas reservoir of the at least two second propellant gas reservoirs of the second sub-system, and
• the second control circuit is operatively connected to the second propellant gas reservoir of the at least two first propellant gas reservoirs of the first sub-system and the first propellant gas reservoir of the at least two second propellant gas reservoirs of the second sub-system.
