TSI CCS Current Legal Reference  
 
The revised TSI for the onboard and trackside CCS subsystems was adopted by Commission Regulation (EU) 2016/919 (Corrigendum) published in the Official Journal of the European Union on the 15th June 2016.
  
This revision concerns the amendment and recast of the CCS TSI as per Commission Decision 2012/88/EU. The main modifications are the following:
  • Editorial improvements and clarifications in the TSI text
  • Introduction of GSM-R Baseline 1 specifications replacing Baseline 0
  • Introduction of  ETCS Baseline 3 release 2 specifications (B3R2) as a new set of mandatory specifications that will coexist in parallel with the current Baseline 2 and Baseline 3.
  • Maintenance of ETCS Baseline 3 Maintenance release 1 (B3 MR1), on the basis of two Technical Opinions of the Agency already approved (ERA/OPI/2014-8 and  ERA/OPI/2015-6)
  • Changes in Chapter 7 to align with the revised ERTMS European Deployment Plan to be adopted under a separate legal basis.
The list of train protection Class B systems is in an Agency technical document. The TSI is supported by a specific part of the TSI application guide, which also contains the references to informative specifications.
 
The ERTMS specifications are managed according to the Agency Change Control Management (CCM).
 
In order to facilitate transparency and interoperability between the different sets of specifications laid down in the TSI Control-Command and Signalling, a double exercise for assessing the compatibility of the ETCS B3 MR1 and ETCS B3 R2 have been carried out. These two documents are referenced in the TSI application guide.
 
Furthermore, the Article 10 of the TSI CCS (Commission Regulation (EU) 2016/919) requests to the Agency to identify all errors that potentially could not allow the system to provide a normal service and to publish as early as possible the respective solutions to correct them as well as the evaluation of their impact in the compatibility and stability of the existing ERTMS deployment. This work has been undertaken by the Agency in cooperation with the sector and has resulted in an Agency’s technical opinion (ERA/OPI/2017-2) and the related compatibility assessment, identified solutions and proposed mitigation measures.
The Agency has also issued an Opinion (ERA/OPI/2017-5) recommending the update of the set of specifications #2 (ETCS B3 MR1) and #3 (ETCS B3 R2) of the TSI CCS (Commission Regulation (EU) 2016/919) concerning the on-board test specifications.
The TSI CCS (Commission Regulation (EU) 2016/919) is complemented by the Commission Regulation (EU) 2017/6 of 5 January 2017 on the European Rail Traffic Management System European deployment plan, which lays down the timetable for the trackside deployment of the ERTMS on core network corridors (CNC).
