Characteristics of a water sprinkler which sprays rectangularly distributed water on railway tracks on which high-speed trains run, and keeps the snow in wet condition in order to protect the running gear and underfloor equipment of vehicles from the snow damage are discussed. Field tests show excellent results of more than 70% in the equality coefficient and more than 60% in the sprinkling efficiency. The new sprinkler covers the entire track area instead of a limited circle covered by the conventional sprinkler so that it will be possible to operate the Tokaido Shinkansen trains in winter at a faster speed than at present.
