Metro Train Control System
The wireless system provides the control and monitoring link between the fixed basestation and the various trains moving in each section. Where the trains move in tunnels the system uses a lossy-line ("leaky-feeder") along the center of the track that creates a controlled electromagnetic field to establish a reliable link with redundant radios on the trains. With our custom firmware the trackside basestations can poll over 50 trains in a track every second. According to Bombardier's website :
"CITYFLO 650" is a system for driverless (DTO) or unattended (UTO) train operations designed for moving block advanced metro operations and airport people movers (APM). The track to train communication is achieved via a state-of-the-art wireless technology to provide bi-directional communication. The system is used for automatic running of trains on segregated tracks."
