Abstract
A pair of transmission linesare provided in the train in such a manner that, at each of the two ends of each of the carriage groups, one of the train end detection switchesis connected to one of the pair of transmission lines. A resistoris inserted in at least one of the pair of transmission lines, and a voltage detector measures a voltage V, Vbetween the pair of transmission lines at each of both ends of the resistor. A controlling unit controls a first and a second switchesin such a manner that there is only one location within the train where a power supplyis inserted between the pair of transmission lines, and the controlling unit recognizes the configuration of the train based on the voltages that have been measured by the voltage detectors.
