  2. Computer Based Interlocking (CBI)
  3. Zone Controller (ZC)
  4. Wayside Equipment
  • Lineside Electric Unit (LEU)
  • Secondary Train -Detection System (E.g.: Axle Counter)
  • Signal & Point Machine
  • Onboard System
  1. Vehicle Onboard Controller (VOBC)
  2. Wireless Communication Unit (WCU)
  3. Balise Transponder Module (BTM)
  • Data Communication System (DCS)
  1. Wayside Radio
  2. Wireless Access Point
