Ten Diverse Formal Models for a CBTC Automatic Train Supervision System [PDF]
Electronic Proceedings in Theoretical Computer Science, 2018 Communications-based Train Control (CBTC) systems are metro signalling platforms, which coordinate and protect the movements of trains within the tracks of a station, and between different stations. In CBTC platforms, a prominent role is played by the Automatic Train Supervision (ATS) system, which automatically dispatches and routes trains within the ...

Detecting Intrusions in CBTC Systems with Mixed-Mode Operations
2025 IEEE 101st Vehicular Technology Conference (VTC2025-Spring)Train control systems provide for the safe operation of railways by synchronizing the movement of trains and maintaining their separation along shared railway tracks. However, the use of wireless data transmissions in Communications-Based Train Control (CBTC) systems has rendered railways vulnerable to cyber attacks.
