PROBLEM TO BE SOLVED: To provide a method of applying oil on rails and a device thereof which suppress the wear and noise of inside and outside rails and prevent derailing on curved rails. SOLUTION: The device is structured to apply an appropriate amount of oil on a rail tread surface 1012 of the inside rail 101 on the curved rail whose curve radius is not less than 200 m and not more than 600 m and not to apply the oil on another rail tread surface 1022 and a gauge corner 1023 of the outside rail 102. On sharply curved rails whose curve radius is not more than 200 m, it is made possible to apply oil to the gauge corner 1023 of the outside rail 102, too, at a differential time interval in addition to the application of oil to the rail tread surface part 1012 of the inside rail 101.
