PURPOSE: A fluid sprayer for reducing noise in a railway is provided to reduce abrasion and noise occurred when a railway vehicle is operated. CONSTITUTION: A fluid sprayer for reducing noise in a railway comprises a sensor(100), a nozzle(200), a protection cap(300), a bubble generator, a main tank(500), a high pressure pump(600), an auxiliary tank(700), a quantitative pump(710), a stirrer(510), and a control box(800). The sensor senses a railway vehicle. The nozzle is installed around a rail(10). The protection cap coupled to the front end of the nozzle. The bubble generator is installed inside the nozzle. The main tank stores fluid for reducing noise. The high pressure pump sprays the fluid with high pressure. The auxiliary tank is connected to the main tank and stores a lubricant with extreme pressure. The quantitative pump supplies the water-soluble lubricant to the main tank. The stirrer forcefully mixes the lubricant with water.
