The HSR-350x, also known as G7, KHST, or NG-KTX, is an experimental South Korean high-speed train.

Here are some of its key features and details:

• Development: It was developed in a joint project that started in 1996, involving government research institutes, universities, and private companies, to reduce reliance on imported high-speed rail technology.
• Purpose: The train was designed as a prototype for commercial trains that could achieve a regular service top speed of 350 km/h (217 mph).
• Technology: Its development included new components like motors, electronics, and passenger car bodies. It was based on TGV technology transferred from GEC-Alsthom.
• Speed Record: In 2004, the HSR-350x achieved a South Korean rail speed record of 352.4 km/h (219 mph).
• Testing: Test runs were carried out between 2002 and 2008.
• Legacy: The HSR-350x served as the foundation for Korail's KTX-II (KTX-Sancheon) commercial high-speed trains.
• Alternative names: G7, KHST, NG-KTX.
• Cost: The G7 program costed 210 billion won, the equivalent of about $208 million USD. The entire development, including testing, cost 256.9 billion won.
