The Tohoku-Hokkaido Shinkansen was damaged in about 940 places, including damage to utility poles and overhead wire fittings, and rail misalignment, due to the earthquake that observed violent shaking with a seismic intensity of over 6 in Fukushima and Miyagi prefectures on the 13th of this month. I understand.
On the 26th, JR East revealed the detailed situation and damage of the Tohoku Shinkansen at the time of the earthquake.
According to this, there are 11 Shinkansen trains that were running at the time of the earthquake, and the original early earthquake detection system, which has the same principle as the Earthquake Early Warning system, brakes and decelerates from 17 seconds or more before strong shaking arrives. There was no damage such as derailment.
On the other hand, regarding the facility, 20 utility poles of the overhead wire that supplies electricity to the Shinkansen were broken, the utility poles were cracked and tilted about 40, the overhead wire was broken at 6 places, and the metal fittings of the overhead wire were damaged. Found in 550 locations.
Furthermore, the rails were displaced in about 220 places, and damage such as viaducts was found in about 70 places, and the number of damages reached 940.
The Tohoku-Hokkaido Line resumed operation on all lines on the 24th of this month, but due to the restoration by emergency measures, the number of trains has been reduced to 80% and the speed has been reduced.
JR East, will not rush the correspondence to return the service number and the time required in the usual way to prospect the next month.
