Train control apparatus

A train control apparatus comprising:

• a first ground device provided in a first section in a train travel path;
• and
• a second ground device provided in a second section in the train travel path, the second section continuing from the first section in a train travel direction,
• wherein the first section includes a control transition section determined using a border between the first and second sections as a terminal end, and an acceptance confirmation request section set before the control transition section in the train travel direction,
• wherein the first ground device transmits and receives information related to train control to and from a train in the first section in accordance with a first communication condition,
• wherein when the train enters the acceptance confirmation request section, the first ground device requests the second ground device to send a report signal including a second communication condition determined by the second ground device in a case of accepting the train to the first ground device,
• wherein when the train enters the control transition section after the first ground device receives the report signal from the second ground device, the first ground device instructs a first radio set mounted on the train to send a first report signal including train location information of the train to the first ground device in accordance with the first communication condition, and instructs a second radio set mounted on the train to send a second report signal including the train location information of the train to the second ground device in accordance with the second communication condition,
• wherein when the first ground device receives the report signal from the second ground device, the first ground device transmits a signal for deleting the border from stop points of the train to at least one of the first and the second radio sets to permit passage of the border, and
• when the first ground device does not receive the report signal from the second ground device, the first ground device transmits a signal to stop the train at or before the border to at least one of the first and second radio sets.
