Experimental Trials for the Future Railway Mobile Communication System in 5GRail Project.

5GRAIL is an EU Horizon 2020 project and part of the funding call on 5G for Connected and Automated Mobility. The project aims at designing and testing the first prototypes of the Future Railways Mobile Communication System (FRMCS) which will become the worldwide standard for railway operational communications [1]. This paper aims at describing the lab environment that has been set-up for 5GRAIL, with a focus on the activities of the French partners as part of Work Package 4 and the kind of tests they have been committed to. Then, activities of Work Package 5 in scope of field tests to be performed in France will be discussed and illustrated with details on the operations led by the railway operator SNCF.
