The estimation method according to the present invention generates a first estimation equation to estimate an outside derailment coefficient Q/Pi of a monitoring bogie 3 in a reference curved section 1, generates a second estimation equation to estimate an outside derailment coefficient Q/P2 of a normal bogie 4 on the reference curved section, generates a third estimation equation to estimate an outside derailment coefficient Q/P3 of the monitoring bogie on the normal curved section 2, generates correction coefficients for the explanatory variables in the second estimation equation based on the coefficients of the explanatory variables in the first estimation equation, the coefficients of the explanatory variables in the third estimation equation, and the like, generates a fourth estimation equation to estimate an outside derailment coefficient Q/P4 of the normal bogie on the normal curved section by taking account of the correction coefficients in the coefficients of the explanatory variables in the second estimation equation, measures wheel load and lateral force of the normal bogie with the measurement equipment 11 on the reference curved section, and then estimates the outside derailment coefficient Q/P4 by inputting the fourth estimation with computed values computed from these as explanatory variables. A method capable of estimating an outside derailment coefficient of a normal bogie on a normal curved section is accordingly provided.
