The invention provides a cross-regional train position tracking method, device and equipment and a storage medium, and the method comprises the steps: obtaining a train vibration signal based on a grating array sensing optical cable, the train vibration signal comprising a plurality of train vibration sub-signals corresponding to a plurality of demodulators; demodulating the plurality of train vibration sub-signals based on a plurality of demodulators, and determining a plurality of train vibration characteristics; determining a plurality of real-time local positions of the train based on the plurality of train vibration characteristics; and determining overlapped train vibration characteristics corresponding to the overlapped measurement areas in the plurality of train vibration characteristics, determining whether the plurality of real-time local positions are combined or not based on the overlapped train vibration characteristics, and performing cross-area tracking on the train. According to the method, the multiple real-time local positions are accurately combined based on the overlapped train vibration characteristics of the overlapped measurement area, and the accuracy and precision of train position tracking are improved.
