KTX-Sancheon power transmission
The train body is designed in the shape of masu salmon (sancheoneo in Korean) to reduce air resistance.
KTX-Sancheon trains were made as high-speed trains using the test car HSR-350X technology developed for a national R&D project. The first mass production train was released in November 2008. Its official name, KTX-Sancheon, was selected through the naming contest held in February 2010.
Increased the transportation capacity by driving 20 cars at the same time as double-deck operation was made possible for 10-car trains.
