Communication-Based Train Control (CBTC)
CBTC is a “moving-block”-based railway signalling system for Metro Railways that makes use of the radio communications between the train and track equipment for the traffic management, infrastructure control, and automatic route setting
Purposes :
- The accurate and exact position of a train is known more than traditional signalling systems.
- Efficient and safe way to manage the railway traffic
Interfaces :
ATP
- Brake Profile, Train Interface Unit (TIU), Tacho Generator
- Cab Signal (onboard computer or OBC), Driver Machine Interface (DMI)
- Train Detection, Train Location, and Speed
- Wayside: Antenna, Balise, Access Point
ATS
- Operations Control Center (OCC)
- Visual Display Unit (VDU) with Automatic Route Setting
ARS
- Computer-based Interlocking (CBI)
ATR
- Movement Authority (using Moving Blocks)
ATO
- Optional Platform Screen Door (PSD)
Features :

Ensures safe train movement with or without driver
