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
  • KD2000

    • The KD2000 system consists of a digital transmitter and receiver used in the AF track circuit of high-speed railways. It continuously analyzes signals from the track circuit to monitor train detection, overcurrent, and operational status.

  • Key Functions and Features

    • 01
      The digital transmitter generates a carrier wave and outputs it to the track circuit.
    • 02
      The digital receiver analyzes the continuous signal received from the track circuit to detect track occupancy.
    • 03
      If the track is not occupied, it outputs the relay operating voltage; if the train occupies the track, it immediately cuts off the relay operating voltage.
    • 04
      The digital transmitter/receiver indicates the operating status with an LED.
