On the 23rd, operation of the Tohoku, Hokuriku, and Joetsu Shinkansen trains was canceled for the entire day in some sections due to problems with overhead wires.
According to JR East, restoration work is underway and, with some exceptions, they plan to operate normally from the first train.
According to JR East, a power outage occurred on the Tohoku, Hokuriku, and Joetsu Shinkansen trains around 10 a.m. on the 23rd, and when staff investigated, they found overhead wires hanging down on the uphill section between Ueno and Omiya, and about 1 km away. It was confirmed that the pantograph of the up-bound Hokuriku Shinkansen ``Kagayaki'' vehicle that had stopped at the station was damaged and the window glass was cracked.
The details of the situation are still being confirmed, but it is believed that the Kagayaki train came into contact with the overhead wire, which had fallen down for some reason.
As a result of this, service continued to be suspended in wide areas, with service being suspended for the entire day on the Tohoku Shinkansen between Tokyo and Sendai, and on the Hokuriku Shinkansen and Joetsu Shinkansen between Tokyo and Takasaki.
According to JR East, a total of 283 trains were suspended, affecting approximately 120,000 people.
Restoration work is currently underway, and with some exceptions, it is planned to operate normally from the first train.
In this incident, two workers who were preparing for recovery work near the site suffered electric shock and were rushed to the hospital, and JR East said it would investigate the cause of the trouble with the overhead wires and the worker's accident. is.
