Study on the Specification Development of the Safety-critical Korean High-speed Rail Interlocking Equipment

In this paper we present the specification development for the localization of interlockings which control routes within a HSR station yard. For the electronic interlockings in Korea introduced from France in the 1990s, it has a complicated hardware configuration and communication protocols in order to secure safety. Now 30 years later, in case of the application of the up-to-date IT technology, it is expected to achieve equal or greater safety and save maintenance costs. Additionally, we develop the specification so as to utilize the stable domestic electronic interlocking technology for general railways, beyond the simple maintenance for the performance maintenance of foreign devices, to high-speed railways. Therefore, we perform a study for the localization of the HSR electronic interlockings by comparing and analyzing interlocking logic units between conventional HSR and general railways.
