Abstract
Train control systems consist of supervisory controller, network, and multiple trains. Actual trains are controlled and supervised by computer based signals, which put this system in the paradigm of CPS (Cyber-Physical Systems). Recent trends in train control systems are adopting wireless communication protocols to improve operational efficiency. While efficiency is improved by overcoming legacy fixed block based operation, wireless communication channels open new surfaces for external attack and malfunction. Actual attacks on CPS indeed have been materialized in trains, and as a result, attention from academia and industry for resiliency for train control systems are increasing. This manuscript overviews the trend and latest effort to this regard and introduces status of train control software that enhances the aspect of automatic diagnosis and real-time monitoring features.
