CONSTITUTION:In the state that a vehicle 6A is stopping at a station B, a switch 37 of a feeder line 23A is closed, a switch 48 of an information transfer line 30 is closed, and a switch 49 is opened. At this time a switch 54 of a feeder line 66B of substation 21B is closed, and a switch 59 of an information tranfer line lead-in line 68B is closed. When a vehicle 6A stops at the station B, a switch 37 is opened, a switch 38 is closed during the stoppage, the switch 48 is opened and the switch 49 is closed similarly. Simultaneously, the switch 39 is closed, the switch 40 is opened, the switch 50 is closed, and the switch 51 is opened. A switch 55 of a substation 21A is closed, a switch 56 is opened, a switch 60 is closed, a switch 61 is opened. Simultaneously, a switch 54 of the substation 21B is opened, the switch 59 is opened and connected to the substation 21A. In this manner, the running way to the station A is formed.</p> |
