A train location measurement system includes a ground device that generates a signal that contains location measuring data, a base stations that each transmit the signal to the train, an onboard station that measures a first received signal strength of a first signal received from a first base station located in a travel direction of the train, and generates, using the location measuring data, first error information indicating an error occurrence status upon reception of the first signal, an onboard station that measures a second received signal strength of a second signal received from a second base station located in a direction opposite the travel direction of the train, and generates, using the location measuring data, second error information indicating an error occurrence status upon reception of the second signal, and an onboard device that measures the location of the train.
