A railroad train includes an integrity monitoring system with a three-axis inertial measurement unit. Incremental rotation values are measured along three reference axes during a plurality of measurement periods using the three-axis inertial measurement unit. A quaternion including first, second and third numerical values representative, respectively, of the measured incremental rotation values along the three reference axes is calculated for each measurement period. An anomalous variation of at least one of the first, second or third numerical values of the calculated quaternion is detected, said anomalous variation being representative of a train break-up condition.
