摘要： A train control apparatus includes a setting reception unit that receives setting information regarding a temporary speed limit section and a speed limit. A control unit generates temporary speed limit information for the trains. A communication unit transmits the temporary speed limit information to the trains. If information regarding all temporary speed limit sections cannot be included in the temporary speed limit information, the control unit includes, in the temporary speed limit information, information regarding a specified number of temporary speed limit sections located on a traveling direction side, and changes a speed limit in one or more temporary speed limit sections included in the temporary speed limit information on the basis of a speed limit set in a temporary speed limit section that is adjacent to a temporary speed limit section included in the temporary speed limit information, and is not included in the temporary speed limit information.
