HEMU-430X (standing for High-Speed Electric Multiple Unit 430 km/h eXperimental) is a South Korean experimental high-speed train designed to achieve a maximum speed of . On 31 March 2013, it achieved a record of during a test run, making South Korea the world's fourth country after France, Japan and China to develop a high-speed train that operates above . The notable feature of this train compared to older South Korean high-speed trains is distributed traction. The commercial versions of these trains, known as KTX-Eum and KTX-Cheongryong, were delivered to Korail from 2020 onwards.

==History== The original 1991 plan for the Korea Train Express (KTX) high-speed rail system foresaw an operating speed of , allowing for a travel time of under two hours between Seoul in the northwest and Busan in the southeast of South Korea, the termini of the first line. Later, the planned top speed was reduced to , the maximum of existing high-speed trains on the market. Korail then ordered high-speed trains based on Alstom's TGV Réseau, the KTX-I, which started KTX service on 1 April 2004, and operates at a top speed increased slightly to in November 2007.
