Earthquake "Very big impact" near the derailment site of the Tohoku Shinkansen

Due to the derailment of the Tohoku Shinkansen running in Miyagi prefecture due to the earthquake on the 16th, there was a very big impact near the site, about 80% to 90% of the Great East Japan Earthquake, based on the values ​​of the measuring instruments installed along the line. That was found in a JR survey.

In addition, we are considering whether it is possible to shorten the section that is out of service, with a policy of proceeding with restoration, such as starting work to return the vehicle to the rail within a few days in parallel with the damage investigation.

Judging future operation policy at the beginning of the week

In the accident where the Tohoku Shinkansen derailed in Shiroishi City, Miyagi Prefecture due to the earthquake on the 16th, JR East conducted investigations along the railway line, and as a result, the rails were distorted in 10 places and the overhead lines were cut in 2 places by the 18th. , 20 damage to structures such as high bridges and 24 damage to utility poles were confirmed.

However, the investigation and inspection, which was expected to be completed by the 18th, will take several more days, and the full extent of the damage is still unknown.

On the other hand, as a result of analyzing the measuring instruments installed along the railway line, the value indicating how much the structure moved due to the earthquake was about 80% to 90% of the Great East Japan Earthquake near the site of the derailment accident, which was a very big impact. It turns out that it was there.

With the policy of proceeding with recovery in parallel with the damage investigation, we will start work to return the derailed vehicle to the rail within a few days.

It is envisioned that a jack can be used to lift and shift the vehicle, or a crane can be used to lift the vehicle and place it on the rails.

In addition, the Tohoku-Hokkaido Shinkansen is currently out of service between Nasushiobara Station and Morioka Station, but JR East said that it may be possible to shorten the out-of-service section based on the damage investigation results, and at the beginning of the week. Will also decide the future operation policy.
