Abstract: In a power supply control system that controls supplied power to a train using a remote control apparatus provided on a substation side and a train-information managing apparatus provided in a train, the train-information managing apparatus transmits present train location information indicating a location where the train is traveling and information concerning consumed/regenerated electric power amount to the remote control apparatus. The remote control apparatus extracts, out of the input consumed/regenerated electric power amount information, based on the present train location information, consumed/regenerated electric power amount information concerning a train traveling in a power section, calculates a total value of the consumed/regenerated electric power amount information, and controls, based on the calculated total value of the consumed/regenerated electric power amount information, electric power amount supplied to the power section.
