This revision concerns the amendment and recast of
the CCS TSI as per Commission Decision 2012/88/EU. The main modifications are
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 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 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
