Hemu stands for high-speed electric multiple unit, but it is also a word in Korean which means sea fog, and is believed by Koreans to be a portent of something good. Hemu430X is the country's third high-speed train. KTX, a 300km/h train based on TGV-R and designed by Alstom, was introduced in April 2004. This was followed by KTX-Sancheon, Korea's first domestically-designed high-speed train. KTX-Sancheon has an output of 8.8MW, double-skinned aluminium body shells and articulated bogies.
