Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of an operation control device for an electric railway vehicle according to a first embodiment of the present invention. This first embodiment is different from the conventional example shown in FIG.
The signal line 6 for transmitting the operation command from the controller to the drive control device 7 is duplicated, and the duplicated signal lines 6a, 6
A switching device 8 for selecting either one of b is additionally provided.

In FIG. 1, the control vehicle 1 is provided with an operation command device 2, and the operation command device 2 includes a command switch 3a for outputting a train forward command or a reverse command and a command switch 3b for outputting a notch command for the train. Is provided. Operation commands from these command switches 3a and 3b are:
The signal is transmitted to the drive control device 7 of the electric vehicle 4 through one of the duplicated signal lines 6a and 6b.

The switching device 8 selects one of the signal lines 6a and 6b, and has a switching switch 9 manually operated by an operator. In FIG. 1, the signal line 6
In this state, when the changeover switch 9 is operated by the operator, the changeover relay 10 is operated, and the signal line 6a is switched to the signal line 6b by the contact.

Normally, the operation command from the operation command device 2 is
The driving is transmitted to the drive control device 7 of each electric vehicle 4 through the signal line 6a and is operated. In this state, if an operation command is not normally transmitted to each drive control device 7 due to, for example, ground fault or contact, the operator operates the changeover switch 9 of the changeover device 8. Thereby, the signal line 6 switches from the signal line 6a to the signal line 6b.

That is, when the changeover switch 9 is turned on, the changeover relay 10 is excited, and the operation command from the control vehicle 1 is switched to the signal line 6b. The contact output of the switching relay 10 is passed to each electric vehicle 4 and is also input to each drive control device 7 to excite the input switching relay 11.
