Abstract: As the railway industry strives to improve customer experience, quality, reliability, safety and security of railway systems, we observe ever increasing information flows between all stakeholders. This trend is accentuated by the latest development of autonomous and connected trains that will need high-performance communications technologies such as 5G and beyond. Some challenges for 5G for railways include extreme mobility, robustness, reliability, high capacity everywhere, spectral efficiency, radio resource scarcity, low latency, low energy consumption and resilience to interference. Safety and security are among the top requirements for railways, including cybersecurity.

Evaluating the performance of 5G-based systems in the context of railway operation requires radio channel models for numerous environments and frequencies (900 MHz and 1900 MHz). Dedicated antennas need to be developed with adequate performance and placement. Innovative solutions at the network level are also needed: complex handover, scheduling aspects, as well as the incorporation of Software-Defined Networking (SDN) and/or Network Function Virtualization (NFV). 5G and beyond architecture promises to deliver significant benefits, including but not limited to, improved service availability, increased reliability and higher throughput. The Internet of Things is also a hot topic for railway in the context of diagnosis and predictive maintenance of both track and rolling stock. At the same time, a lot of developments are currently ongoing to support the development and deployment of the Future Railway Mobile Communication System (FRMCS). This workshop will enable researchers to present the latest results addressing the aforementioned challenges in the context of 5G for railways within the FRMCS landscape.
