Whether or not slip-or-skid of a wheel on any one of a plurality of axles of a train to which pulse generators (PGs) are provided has occurred is determined on the basis of speed pulses output from the PGs. When occurrence of slip-or-skid is detected, a train occupancy range is calculated with a front end portion of the train determined on the basis of a forward-side one of train positions obtained on the basis of the speed pulses output by the PGs, and with a rear end portion of the train determined on the basis of a backward-side one of the train positions. Whether or not any of the PGs is abnormal is determined on the basis of the speed pulses or a speed and acceleration/deceleration calculated from the speed pulses.
