The KRRI developed Korean Advanced Tilting Train, a national key project of the Ministry of Land, Transportation and Maritime Affairs, had a successful test run at a maximum speed of 200km/h. The test took place on the Gyeongbu high-speed line between Daejeon and Osong.

The test run for the Korean Advanced Tilting Train began in April 2007 in Osong on the Chung Cheong line. Testing continued for about two years and four months on the five of domestic lines, which include the Chung Ang, Chungbuuk, Honam, Gyeongbu and Taeback lines. The test run verified the safety and reliability of the Tilting Train, while confirming its ability to achieve superior speeds   on straight and curved section of existing rail. 230 test runs were completed without any interruptions, covering a total distance of 100,000 km. 
The Korean Advanced Tilting Train can maintain speeds of up to 180km/h, even  on the winding tracks of mountainous  terrain. The train is able to maintain high speeds by tilting the car body up to eight degrees when navigating curves.

Saemaeul trains, which are currently the second fastest in Korea after High Speed Trains, have a maximum speed of 140km/h. However, they must significantly reduce their speed to 60km/h on curved tracks in order to avoid derailment. The Korean Advanced Tilting Train, however, is equipped with a device that enables the car body to tilt when navigating curves. This reduces the centrifugal force, while improving the comfort level of passengers and reducing the risk of derailment. 

The Korean Advanced Tilting Train will begin commercial service in 2013 starting with the Chungang line, and later followed by the Taeback and Yeongdong lines. If Tilting Trains replace Mugungwha trains on the Chungang line (Cheongryangri, Seoul to Yeongju, Gyeongbuk), the travel time will be shortened from three hours and thirty five minutes to two hours and fifty five minutes.. Travel time is expected to be further reduced to one hour and fifty five minutes when the installation of double tracks is completed in 2012.
