At Kangnung KTX accident site where 14 people were injured due to derail yesterday (8th), restoration works at night are in full swing. Most of all, it is not easy to pick up the locomotives off the track.

Park Jae-hyun (Yes, I am on the Gangneung KTX derailment site.) How far has the restoration work progressed?

<Reporter>

KORAIL lifts the carriage that was derailed by a crane, and then moves on to the Gangneung car base every night.

All 10 of them derailed, and the locomotive with the cockpit devastated the most, has been restored and moved to the side track.

A car that was connected to the locomotive was moved to the Kangnung vehicle base.

Koleil, who has added 250 people to the restoration work, said that he will do the rest of the day and complete the restoration by 2 am tomorrow.

One of the trains supplying electricity to the trains may also take longer to complete recovery, but it seems that the work will be resilient as the locomotive parts that were completely derailed in the T shape have been restored.

So what is the cause of the derailment?

<Reporter>

Korail said yesterday the possibility of a line fault due to a sudden cold wave.

Oh Young-sik, President of KORAIL

[Oh Young-sik / President of KORAIL: Maybe there are some problems on the track due to the damping of temperature. We keep track of the cause of the accident ... ]

Unlike ordinary trains, KTX has a long section of railways, which means that a steel railway line can suddenly shrink with a cold wave coming in.

The government weighs heavily on the possibility that KTX would automatically bust the gap by recognizing that the sensor is above the line.

It is also investigated whether the signaling system worked properly. It is also possible that the line separator may have been malfunctioning in the accident area where the line is divided.

The Ministry of Land, Infrastructure and Transport is investigating the accident investigation committee.
