KTX and KTX - Sancheon Trains

South Korea boasts a well-developed high-speed railway system, offering comfortable and highly efficient means of travel between the country's capital and other major destinations in short periods.

There are two types of KTX trains, called KTX and KTX-Sancheon which both are operated by Korail. The first KTX was launched in 2004, with high-speed rail lines from Seoul to Busan. KTX-Sancheon began operation on 2010. Now KTX high-speed trains operate along 5 train lines.

It used to take more than 4 hours to reach Busan from Seoul. With advanced KTX trains, this time was reduced to 2 hours and 15 minutes.

The trains are pressure-sealed, which reduces passenger discomfort, especially during tunnel passages. Trains are made of quality materials and triple-glazed glass. The trains are not only fast, but also safe and environmentally friendly. ​
