Main news related to the CCS TSI 2023 (2023/1695)

An English 🇬🇧 translation of a presentation to the speech I gave about the main changes brought by CCS TSI 2023 at the biggest Czech conference on Communications and signalling systems on Railways, which was held in Clarion Hotel Olomouc from 7th to 9th November 2023 (konferenceszt.cz). Attended by around 500 participants and 200 on-line followers.

The original Czech 🇨🇿 version of the presentation can be found here: https://www.slideshare.net/slideshow/hlavni-novinky-souvisejici-s-ccs-tsi-2023-2023-1695/269688092 .

▪new approaches (1/2)
‒single set of specifications
‒advantage: maintained(by error corrections, note: B2 and B3MR1
are not maintained today, maintained is B3R2only)
‒reduced envelopesof ETCS functions (system versions)
‒advantage: quicker availability of products with the selected new functions
on the market (note: full SV 3.0, by removing functions SV 2.3, 2.2, or 2.1)

▪new approaches (2/2)
‒transition regime relates to the CCS TSI changes
‒2 regimes: default (7 years) vs. specific
‒taken from RST TSI, reason: harmonisation of approaches for vehicle as a whole
‒error correctionsin Appendix A CCS TSI
‒newlydefined process for their correction, incl. roles definition and tasks

Conclusions –benefits of new ERTMS-specs
Main news related to the CCS TSI 2023 revision(2023/1695)
▪CCS TSI 2023, EC has published upon ERA‘s recommendation
‒contains error corrections and a lot of functional enhancements (ATO, SM, opti-
misedbraking curves, BMM, reaction on inaccurate ODO, FRMCS readiness…)
‒allows:
‒increasing operational rail capacity –optimised ETCS braking curves & ATO introduction
‒increasing radio transmission capacity –FRMCS readiness
‒saving energy, increasing punctuality and efficiency of rail traffic mngment–ATO GoA1/2
‒reducing number of infra elements –SM, integrity and confirmed train length reporting
‒increasing cyber security –removal of HP data, higher protection of ETCS L2 runs
‒harmonises translationsof texts/messages on DMIfor the first time (Appendix E)
