Deficiencies in TSIs are textual errors, omissions, mistakes in translation or in technical content, or other inconsistencies as referred to in Article 7 of Directive 2008/57/EC.
You can find deficiencies in TSIs already adopted and published on the Official Journal of the European Union.
You cannot find deficiencies in the TSIs which are still in the process of being drafted by the ERA or in any following approval step.
Updated list of TSI deficiencies is provided regularly to RISC meetings.
NOTE: The management of deficiencies in the TSIs concerns the correction of the content of the TSIs as specified in Article 5(3) of Directive 2008/57/EC. It does not concern the evolution of the technical documents published by the Agency and referred to in the TSIs in accordance with Article 5(8) of Directive 2008/57/EC. Similarly, this document does not cover the Change Control Management for the ERTMS specifications and documents listed in the Annex A of the TSI on control-command and signalling.
