The present invention relates to a subway station facility-connected water supply-type fire extinguishing system for a railroad vehicle, wherein the system comprises: a subway station fire extinguishing facility installed in a subway station at which a railroad vehicle stops, and supplying water as a fire extinguishing agent when a fire breaks out in the subway station; fire detectors installed in the interior of the railroad vehicle and detecting whether or not the fire breaks out; heads installed in the interior of the railroad vehicle and spraying the water, which is supplied from the subway station fire extinguishing facility, into the interior of the railroad vehicle while converting the water into droplets; electronic valves controlling the injection of the water into the heads; water supply coupling units connecting the subway station fire extinguishing facility and pipes inside the railroad vehicles so that the water supplied from the subway station fire extinguishing facility can be guided to the heads through the pipes inside the railroad vehicle; and a device control unit controlling the subway station fire extinguishing facility and electronic valves so that firewater can be injected into the heads when the fire is detected by the fire detectors. According to the present invention, water can be continuously supplied from a subway station outside a railroad vehicle without mounting a water tank and a gas tank inside the railroad vehicle so that fire extinguishing efficiency can be improved, wherein the water tank and the gas tank are fire extinguishing facilities for the railroad vehicle.
