An engineer who drove a KTX in a cab with a broken air conditioner collapsed during operation. I called the cabin staff and rubbed my body, and when I was over 360 passengers, I was exposed to a safety accident.

KTX engineer Lee Mo, who left Pohang last night for Seoul, suffered paralysis in his face and hands and feet within an hour of departure.

The cause was a long period of time in a high temperature operating environment near 40 degrees.

In fact, the air conditioner had already broken down in the morning, but the engineer arrived at Daejeon station and could not stand it anymore.

[Lee / KTX Engineer: It's high speed, so it's open. The train captain came and shivered together, so . You can't stop in a tunnel and you have to drive, so even if I die.]

As you are responsible for speed control and braking, the comfortable driving environment is often ignored.

[KTX Engineer: (Passenger side) Fix it first, and the cab needs to be fixed, but if you run out of time, you can let go. It doesn't matter. I sold tickets.]

There are not enough people to cope with the emergency.

In the event of a driver's problem, the only person who can help is the train team leader and the crew.

[Park Heung-soo / Railroad Research Fellow, Social Research Institute: (train team leader) The person responsible for the passenger safety (like this accident) had an abnormality in the engineer and took action, so that there was a gap in passenger safety. ]

KORAIL said that repairs were not made on time due to lack of maintenance vehicle bases.
