METHOD OF FIGHTING A FIRE IN A RAILWAY TRAIN Russian patent published in 2015 - IPC A62C2/00 

FIELD: fire safety.

SUBSTANCE: the cavities-ducts are made in wagon walls, which are connected to the compressed air receiver connected to the compressor. In the areas of the greatest risk of fire break-out in cavities-ducts the windows are made with sealed lids. Each window with a sealed lid has a container with the fire extinguishing agent, equipped with a siphon tube and an air nozzle connected to the cavity-duct through the pulse valve. Near each window a temperature sensor is mounted, giving signals to the fire extinguishing control on fire break-out or its termination. On the temperature sensor signal using the reversing electromagnetic valve the lid of this window is opened. The pulse valve is opened, designed for creating repeated short-time pulses of pressure in the air nozzle of the window in the area of fire break-out. By knocking down flame from the burning objects and pouring with dispersed portions of the fire extinguishing agent the burning area is extinguished.

EFFECT: increased efficiency and rapidness of fire extinguishing.
