The modernization work of the Finnish railway train control system is in progress and the first commercial ETCS (European Train Control System) line is planned to be operational during the year 2027. The Digirail project – which is responsible for the transformation – has set an ambitious goal to be one of the first to implement ETCS over FRMCS (Future Railway Mobile Communication System). The FRMCS deployment is planned to mainly use commercially available mobile radio networks.

During the Spring of 2022, Digirail conducted a measurement campaign to assess the commercially available radio network coverage and performance throughout the entire Finnish railway. The length of the measured national railway network was approximately 6000 kilometres. The measurement targets were to verify the available coverage levels of the Finnish mobile networks, the reliability of the mobile networks and how the requirements of the narrow band FRMCS applications would be met.
