The KTX section of the accident is where the track separates.

The train derailed at the point where the track split into two, and it stopped 500 meters after the emergency.

President Koryei mentioned the possibility of an abnormal track due to a sudden cold wave.

[Oh Yeong-sik / President of KORAIL: I think that there may be some problems on the track due to the drought of Gion. .]

Unlike ordinary railway lines, KTX railways have a long section, which means that a steel railway line can suddenly contract with a cold wave, creating a gap between lines.

The government is weighing the possibility that the KTX locomotive may have automatically rushed to the station as the control system recognized this gap as more than a track.

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.

[Kook-in / KORAIL Kangwon Headquarters Safety Environment Director: It is judged that a signal failure occurred in the middle. If the signal is abnormal, the locomotive must stop ... .]

However, the accident trains agency said in the survey of the railway authorities that "it was normal to be signaled at the time of the accident."

The engineer did not identify the problem and was in a hurry.

It is estimated that it will take about two days for the Ministry of Land, Infrastructure and Transport to investigate the cause of the interim investigation,
