Overview
Driverless Wireless Train Control for Safer, Higher-Capacity Urban Metros
Embedded Files
Existing track-circuit systems are being replaced by WiFi/LTE-based train control.
Urban metros must enhance safety with real-time monitoring of trains and boarding.
Operators need greater line capacity by safely shortening train separation.
Wireless train control supports driverless operation with continuous train-position tracking.
Minimized trackside equipment and simple architecture reduce maintenance workload and cost.
Core Competencies
Purpose
Wireless communication–based train control system that supports driverless operation and enhances safety and line capacity for urban metros.
Wireless Communication–Based Train Control
Wireless Communication–Based Train Control
Radio-based train control eliminates track circuits and uses WiFi/LTE-R for wayside–train communication.
High-Precision Train Localization & Moving-Block Control
High-Precision Train Localization & Moving-Block Control
Continuously tracks train positions with high precision along the line.
Applies moving-block control instead of fixed blocks to optimize safe train spacing.
Real-Time Monitoring & Automatic Train Control
Real-Time Monitoring & Automatic Train Control
Monitors train position, interlocking status, signal aspects, and other operation data in real time.
Supports automatic departure and train-control actions based on real-time operating conditions.
Integrated ATS/ATP/ATO and Electronic Interlocking
Integrated ATS/ATP/ATO and Electronic Interlocking
ATS, ATP (wayside/onboard), ATO, and electronic interlocking are integrated to perform vital safety functions.
Expected Benefits
Enhances train-operation safety via real-time monitoring of movement and passenger boarding.
Increases track capacity by safely reducing headways between consecutive trains.
Reduces maintenance costs by minimizing trackside signal equipment and simplifying the system.
Improves service reliability through quick fault response and stable driverless operation.
Certifications
Established as Korean Railway Standard KRS SG-0069 for urban driverless train control.
TRL 9
Full-scale deployment level (TRL 9).
