The invention discloses a multi-sensor train positioning method and system. The method comprises the following steps: acquiring respective measurement data of an inertial measurement unit, a wheel speed sensor and a satellite data processing unit on a train; the inertial measurement unit is used as a reference system, the wheel speed sensor and the satellite data processing unit are used as calibration systems, and the measurement data are fused to obtain the current position of the train; and determining the current section of the train according to the current position and the electronic map of the train track. According to the embodiment of the invention, the train can be accurately positioned without a ground transponder.
