PROBLEM TO BE SOLVED: To provide a correction method for a railway vehicle overturning limit wind speed that improves accuracy of an operation regulation method based on a measurement result by an anemometer and an overturning limit wind speed.SOLUTION: A correction method for a railway vehicle overturning limit wind speed calculated in consideration of air force by the wind to the side face of a railway vehicle includes a step for calculating a correction coefficient of the overturning limit wind speed based on the maximum value of the wind speed at a predetermined position on the side face of the railway vehicle and the maximum value of a spatial average wind speed on the side face of the railway vehicle, and a step for correcting the overturning limit wind speed based on the calculated correction coefficient. By using the corrected overturning limit wind speed, safe railway transportation is achieved without imposing excessive operation regulations.SELECTED DRAWING: Figure 2
