Korea's high-speed train...It is KTX. Korea's high-speed train opened in April 2004 and has been operating until today. The technology was first introduced in France, but now it has been completely localized so that foreign technology cannot be seen anywhere else. Starting with the first trip to Busan, most of the major areas in Korea now have high-speed train routes and construction is still underway. The maximum speed of the train is 300k, and today I only rode the train until Daejeon. In the past, it used to take about five hours to go back and forth to and from Daejeon, but now there are people who go to work in Daejeon. I was satisfied that the train was in a pleasant state without vibration and noise while running.
