PROBLEM TO BE SOLVED: To operate point switching of a railroad model having a plurality of switching points from one portion, and to dispense with wiring between a control part and the switching points. SOLUTION: This rail is provided with child devices at every switching point connected to the respective switching points by a wire and disposed near the respective switching points to apply an electric current for switching the point to the respective switching points, and one parent device disposed electrically in non-contact state to all of the child devices to transmit a data signal for switching the point to all of the child devices. In switching the point, when switching of a designated switching point is input by an input means 22 of the parent device, a data creating part 24 creates a data signal related to the switching point, and the data signal is all transmitted to all of the child devices from an output part 28. All of the child devices receive the data signal from the parent device by a receiving part 30, and in response to the received data signal, the concerned child device performs switching of the switching point to which the child device is connected according to the switching information contained in the data signal.
