Provided are a train control system, on-ground control device, and on-vehicle control device, whereby a wireless communication line is ensured in a more stable and continuous fashion between the on-ground control device and the on-vehicle control device. First and second wireless broadcast-capable regions associated with first and second groups of pluralities of wireless base stations have a wireless broadcasting overlap region. First and second hub devices set first and second on-track ascertainment zones in which the train position is ascertained on the basis of train positional information. An on-track ascertainment overlap zone is set for the first and second on-track ascertainment zones. In this arrangement, the first and second hub devices have an inter-hub data processor for transmitting on-track information acquired by one of the hub devices in the on-track ascertainment overlap zone to the other hub device via an inter-hub network. |
