自動列車制御装置
In addition to Automatic Train Control (ATC) for high-speed lines and traditional Automatic train stop (ATS) for conventional lines, the trains were among the first to be equipped with the new domestically developed ATP automatic train protection system. The ERTMS-compatible system is meant as an improvement over ATS on conventional lines, and makes shorter braking distances possible by allowing braking from full speed to stop in one step.
