Norske tog have entered into an agreement with Siemens on the delivery of new cab radio systems. The current cab radio have been discontinued, and a new type of cab radio is therefore needed.
About the project
GSM-R (the R stands for Railway) is a closed mobile network in the form of a digital radio communications system designed for use on European railways. All locomotives and train sets must therefore be equipped with approved cab radio systems in order to operate on the railways.
Production of the cab radio system (Mesa 25) that has been used to date has been discontinued. New trains delivered to Norske Tog in recent years have therefore had Mesa 25 systems retrofitted from old vehicles that have been phased out. We have now reached the point where the number of new procurements is greater than the number of vehicles being phased out, which is why there is a need to produce new cab radio systems.
The need to produce new cab radios coincides with a technological overhaul which is planned to take place in Norway during the period 2025-2030. This will see the communications standard gradually change from GSM-R to the Future Railway Mobile Communications System (FRMCS) standard. 5G is used as the technological cornerstone of FRMCS.
Therefore, it must be possible to upgrade new cab radio systems as this shift takes place and they must be ready for the migration from GSM-R to FRMCS.
The new cab radio system will be fitted to all new trains. Additionally, Norske Tog will replace current cab radios in a number of older vehicle classes.
In July 2020, Norske Tog signed a framework agreement with Siemens Mobility Limited and Siemens Mobility AS for the delivery of cab radio systems.
In Norway, the overall responsibility for the GSM-R system, as well as ensuring that the network and cab radio systems are able to maintain communications, lies with Bane NOR. Bane NOR is also obliged to approve the train companies’ cab radios and telephones, including the software.
The train operators are responsible for ensuring that they have approved radios and telephones fitted, as well as making sure that their staff have received training in the use of such equipment.
