Following the derailment of the Tohoku-Hokkaido Shinkansen due to an earthquake that observed a seismic intensity of 6 upper, a countermeasures council was held on the 31st in which the national government and JR companies participated. We confirmed the need to analyze the accidents and verify which method is effective.
On the Tohoku-Hokkaido Line, the earthquake on the 16th of this month derailed a train running in Miyagi Prefecture and injured five passengers.
At the countermeasures council held on the 31st, the Ministry of Land, Infrastructure, Transport and Tourism and the officers in charge of safety management of JR5, which operates the Shinkansen, attended.
Most of the meetings were held privately, but from JR East, most of the cars were derailed in this accident, and some of the wheels were not within the expected range, and they were significantly off the rails. That was reported.
In JR East, the emphasis is not on preventing derailment itself, but on minimizing damage when derailing, such as installing a device called a "deviation prevention guide" to prevent the wheels from derailing significantly from the rail.
The government and JR are going to analyze whether it can be said that the measures based on this way of thinking worked with this derailment.
In addition, it is necessary for the council to verify which method is effective based on the current situation that each company has different methods, such as taking measures focusing on preventing derailment itself by JR Central and JR Kyushu. I confirmed the sex.Keywords:
