Due to the trouble that occurred at the substation on the 9th, the Tokyo Metropolitan Transportation Bureau planned to operate the Toei Subway Oedo Line on Saturdays and holidays until the last train on the 10th. We decided to increase the number of trains during the evening rush hour on the 10th.
According to the Tokyo Metropolitan Transportation Bureau, after 11:00 am on the 9th, at a substation that supplies power to the Toei Oedo Line, a broken cable touched the ground and a current flowed outside, a phenomenon called a "ground fault". Occurred.
As a result, the operation of the substation stopped, and the operation of the Oedo Line was temporarily suspended.
Regarding the operation on the 10th, the metropolitan transportation bureau said, ``There is a possibility that the power required for the operation of the weekday schedule will not be covered.'' We had planned to operate according to the timetable, but we decided to increase the number of trains during the rush hour on the evening of the 10th, as restoration work had been completed after replacing the broken line.
From the 11th, it means that it will operate on a regular schedule.
