The Project Evolution of Railway Radio  
The Agency, in its task as System Authority for the European Railway Traffic Management System (ERTMS), leads the essential activities to enable the timely introduction of new radio system(s) to mitigate the risk of GSM-R obsolescence. Following the principles stated in the 2012 MoU on ERTMS, this will be done by introducing the necessary provisions in the CCS TSI enabling migration of technologies that can be used by the trackside and on-board from GSM-R to a next generation system.
The European Commission is expecting the identification of the necessary changes to the current legal framework around 2018 and a replacing system to be available for deployment around 2022. The Project on evolution of railway radio is included in the Agency's multi-annual workplan.
The Project scope is directly related to the functionalities included in the CCS TSI.  This means that the main applications of the current radio system, as defined in the CCS TSI, are considered as reference and co-existence with these applications is mandatory. However, the system shall be capable to support future changes and extensions of the applications covered by the CCS TSI and other TSI’s, as well as railway related applications outside TSI’s. The provisioning of mobile communication services that are usually offered by public networks to passengers (e.g. internet access) is out of scope.
The Project plan covers all activities to be performed by the Agency that are essential to update the CCS TSI to allow other system(s) in coexistence of GSM-R.  The Project consists of the following steps:
  • Performing studies on relevant subjects and define options.
  • Select the relevant option(s) and provide justification (including impact assessment)
  • Conclude on Requirements and Specifications, to be included in the CCS TSI
The current Project plan focuses on the period until end of 2018, in which the requirements and essential documents have to be delivered.
In a later stage, the plan will be updated with the activities for the period 2019 – 2022, focusing on the finalisation of specifications and their validation.
