PURPOSE:To switch a substation by an operator without any intention when an electric railcar runs from a block section having an electric railcar to next block section. CONSTITUTION:When an electric railcar 6A receives power through a switch 34p and a trolley wire 23 from a substation 1A to run and receives a stop signal from a ground element 37 before a station (l), the railcar stops at the prescribed position on the element 35m in the station (l) according to a deceleration pattern. When the railcar 6A stops, a car controller 12 transmits a substation power switch request signal from a car transmitter 13 under the conditions that the output of a tachometer generator 15 is 0 and a stop signal from the element 35m is input. A substation controller 32m opens a switch 34p, closes 34q, opens a switch 34s and closes 34r when the preceding car does not exist in the next block section to supply power from the substation 1m. Then, a stop presence release signal is transmitted from the element 35m. |
