[Asia Economy Reporter Hyungsoo Park] Daea TIAI, a domestic railway signal control system specialist, announced on the 20th that it applied the 'Korean Train Control System' pilot project on the Jeolla Line, which was successfully ordered in May 2020, to the section connecting Iksan and Yeosu Expo.
The Korean Train Control System (KTCS-2) is the world's first to apply the 4th generation wireless communication-based railway communication network (LTE-R). It complies with the European standard ETCS, allowing compatibility with overseas signaling systems.
From December 2015 to June 2018, Daea TIAI participated in the production and installation of the Korean wireless communication-based train control system for conventional and high-speed railroads, a national R&D project by the Ministry of Land, Infrastructure and Transport.
Daea TIAI developed the Radio Block Center (RBC), which ensures safety by controlling train intervals, and completed field verification on both high-speed and conventional lines. It obtained the highest safety grade SIL 4 from the international safety evaluation agency (Germany T?V S?D). Testing was completed using test equipment and procedures from a European accredited testing laboratory.
Having secured the KTCS-2 Jeolla Line pilot project for three sections (180Km), Daea TIAI completed testing before system installation based on identical track conditions for the project section. Facility verification tests were conducted according to the Railway Safety Act to confirm train operation safety.
In the pilot project, Daea TIAI supplied the entire ground signal system, including the Radio Block Center (RBC) and Block Information Transmission Unit (BITU), which transmits key information to trackside in real time; the Key Management Center (KMC), a cryptographic key management device for securing wireless data transmission between ground and trains; and the Electronic Interlocking System (EIS), which secures train safety within station premises and sets routes.
The government plans to invest a total project cost of 2.2 trillion KRW in the KTCS-2 project by 2032. Daea TIAI, responsible for the three pilot project sections, is expected to play an important role in the KTCS-2 project.
The pilot project succeeded in complete localization of railway signaling technology, which previously depended on foreign technology. Preparations for the overseas market entry of the Korean Train Control System have also been completed.
A Daea TIAI official said, "Based on the KTCS-2 system developed purely with domestic technology, we expect to build a signaling system that can connect to Europe through North Korea, China, and the Eurasian railways."
