Abstract

A train-position locating device includes an onboard control device incorporated in a train and a ground control device installed on a ground. The onboard control device decides a track on which a train is present based on position information and a result of a nearest track search, transmits identification information for identifying the own train and track information to the ground control device, and shifts to an onboard-oriented train control mode when receiving a response indicating 'position is located' from the ground control device. The ground control device transmits a response indicating 'tentative position is normal' to the onboard control device when another train located to be present on a track is not present on the tentative position, and transmits the response indicating “position is located” to the onboard control device when a change from a previous track to the changed track is correct.
