KTX-I
The KTX-I, also known as the TGV-K or Korail Class 100000, is a South Korean high speed train class based on the French TGV Réseau. The 20-car formation of the trainsets without restaurant car is optimized for high capacity. The 46 trainsets were built partly in France and partly in South Korea in the framework of a technology transfer agreement, which was the basis for further domestic high-speed train development in South Korea.

Korail uses the name of KTX as the official name of KTX-I. The name of KTX-I is derived to distinguish KTX-Sancheon, which was formerly called as KTX-II, but it is not the official name for this rolling stock.
The high-speed rail service of South Korea's national rail carrier Korail, Korea Train Express (KTX), started with the KTX-I. The operational reliability of the trains was improved over time with better maintenance and minor modifications. As of 2011, the KTX-I remains Korail's main workhorse in KTX service with a maximum scheduled speed of 305 km/h (190 mph).
