Following recent developments in information and communication technology (ICT), various research and development projects are ongoing around the world to propose new train control technology for safer and more stable transportation services. In particular, 5th generation mobile communication network systems (5G) which will be partially available in 2019 are expected to be used for critical roles in various safety related systems in the future, such as for automatic driving systems for road vehicles and train control systems. This paper outlines recent trends in basic studies for utilizing various communication network techniques including content centric network techniques and 5G systems to sophisticate signalling systems and train control systems. This paper also introduces a future plan for the challenges of the developing autonomous train operation and control system to realize safer, more stable and low-cost train operation services.
