Trackside Signaling Device

The trackside signaling device is installed along the railway to ensure the safe and efficient operation of trains.
It primarily detects train speed, position, and direction to control train movements and maintain safe intervals between trains.

Trackside Signaling Device
  • IP-based Station Information Transmission Device

    • The IP-based station information transmission device is a system installed in the machine room of field stations on both conventional and high-speed lines.
    • It receives display information from the interlocking device (or FEPOL) and transmits it to the control center to monitor train operation status.
    • After receiving control commands from the control center, it performs the function of transmitting the corresponding commands to the interlocking device (or FEPOL).
