The revised
CCS TSI for HS and CR transeuropean rail has been adopted by a Commission Decision 2012/88/EU on the 25
th January 2012. It has been published in the Official Journal of the European Union on the 23
rd February 2012.
This TSI merges the former TSI for HS and CR introducing improvements mainly:
- separate on-board and track-side subsystems according to the amended annexe 2 of the interoperability directive,
- improved description of the certification process in chapter 6,
- closing of a first set of important open points on compatibility of train detection systems in the Interfaces between CCS track-side and other subsystems referenced in annex A,
- migration criteria for train detection systems.
This TSI does not introduce modifications to the EU ERTMS deployment plan.
The ETCS Baseline 2 specifications originally adopted by the Decision 2008/386/EC are today the basis of the interoperable deployment of the system in Europe.
They were integrated with the ETCS test specifications in 2010 by commission decision 2010/79/EC. The Annex A of the revised TSI in 2012 also introduces better interface definition for the management of the cryptographic keys, improved colors and reflectivity definition for the track-side maker board, more consistent definition of the ETCS variables used in project parametrization.
This TSI is supported by a specific part of the
TSI application guide, which also contains the references to informative specifications.
