Before the development of the KTCS,
South Korea did not have domestically produced train signal control system technology, so most of the core technology was imported. Afterwards, it was developed according to the national
Research and development (R&D) project, the domestic signal system standardization and domestic production plan. If the
Gyeongbu high-speed train signal control system is built in the country's version, KTCS-2, it will be possible to save about 1.2 trillion
South Korean won or more in budget compared to the existing foreign system, and it will also be possible to provide infrastructure that supports operating speeds of up to 320 km/h. In 2012, the Korea Railroad Research Institute,
Korail and
Hyundai Rotem participated as research institutes in a project led by the
Ministry of Land, Infrastructure and Transport. In 2018, the world's first
LTE-R wireless communication-based train control system, KTCS-2, was developed as a national R&D project, and KTCS-2, manufactured by Hyundai Rotem, completed R&D, performance verification, and product certification in the same year. In 2022, KTCS-2 successfully completed commercial operation on the
Jeolla Line. As of 2024, the design for introduction to the
Gyeongbu high-speed railway for
KTX (Korea Train Express) is currently underway. == Usage ==
