Korean Train Control System

The Korean Train Control System (KTCS) is a train protection system established as a standard specification for the South Korean railway.

Originally, KTCS-1 is designed for urban transit lines, KTCS-2 for general lines, KTCS-3 for high-speed lines.

Since earlier than April 2018, the development has been renewed. Now KTCS system consists of KTCS-2 (for general and high-speed lines), KTCS-3 (next-generation system based on Moving block) and KTCS-M (formerly was KRTCS-1, for Urban rail transit).
