To provide a method that enables a contact position of a wheel of a railroad vehicle with a rail to be measured on a track side, and to provide a method that enables a lateral pressure of the railroad vehicle to be highly accurately measured on the track side, using the method allowing for the measurement of the contact position thereof.SOLUTION: A method is configured to measure a contact position of a wheel of a railroad vehicle with a rail R along which the railroad vehicle travels. The method includes: a wheel weight/lateral pressure measurement step of measuring, on a track side, a wheel weight/lateral pressure: an amount-of-inclination measurement step of measuring, on the track side, an amount of inclination of the rail inclining laterally between tracks because of action of a lateral pressure more than a prescribed lateral pressure on the rail; and a contact position calculation step of calculating a contact position on the basis of the wheel weight/lateral pressure measured in the wheel weight/lateral pressure measurement step, and the amount of inclination of the rail measured in the amount-of-inclination measurement step. Further, the method includes a horizontal load calculation step of calculating a horizontal load acting on between the wheel and the rail on the basis of the wheel weight/lateral pressure measured in the wheel weight/lateral pressure measurement step, and the contact position calculated in the contact position calculation step.SELECTED DRAWING: Figure 1
