Article 1 
This Decision sets out the specific objectives according to which new technical specifications for interoperability (‘TSIs’) shall be developed or existing TSIs shall be amended.
Article 2 
In drafting TSIs and amendments thereto upon the Commission requests pursuant to Article 5(2) of Directive (EU) 2016/797, the Agency shall follow the specific objectives laid down in Articles 3 to 14 of this Decision.
The Agency shall make recommendations to the Commission after taking into account the estimated costs and benefits of the specific objectives referred to in the first subparagraph.
Article 3 

1. The TSIs shall cover the whole Union railway system in a way which avoids duplication, provides a more direct correspondence between subsystems, essential requirements and TSIs, and allows for a coherent definition of the strategies for the application of the TSIs.For that purpose, different possible scenarios and corresponding impact assessments shall be developed.
2. The geographical and technical scope of each TSI shall be reviewed to take into account the requirements set out in Article 1(3) to (5) of Directive (EU) 2016/797.
3. TSIs shall be reviewed where appropriate to ensure the right balance between rule-based and risk-based approaches.
4. The correspondence between the basic parameters and the applicable essential requirements shall be reviewed for each TSI as well as the interfaces with the other subsystems.
5. The TSIs shall, where appropriate, include provisions which:
(a) take into account possible impact on and interfaces with other TSIs and existing relevant strategies, policies and Union legislation, and ensure coherence between them. The TSIs shall, whenever possible, preserve the provisions in force aimed at removing technical barriers to interoperability;
(b) take into account the developments of the Union railway system and related research and innovation activities, and integrate them when they reach the appropriate level of maturity;
(c) close the remaining open points;
(d) take into account the evolution of technical requirements applicable in the 1 520 mm track gauge networks of third countries;
(e) harmonise definitions, in addition to the ones listed in Directive (EU) 2016/797, between TSIs;
(f) integrate references to standards and to other technical documents evolving regularly in a way which allows their updating in a timely manner;
(g) review the number of interoperability constituents and, where appropriate, increase it;
(h) indicate whether the conformity assessment bodies which were already notified on the basis of a previous version of the TSI, need to be re-notified, and whether a simplified notification process shall be applied. In all cases, the related conditions applicable shall be specified;
(i) take into account the sector's best practice and review the choice of modules prescribed in the procedures for conformity assessment of interoperability constituents and subsystems;
(j) reduce the risk of derailment as well as the safety impact on people and the environment in case of derailment;
(k) in considering possible solutions to safety-related issues, take into account all possible causes of those issues including, to the extent possible, those linked to security incidents, without compromising safety or interoperability;
(l) improve energy efficiency of the relevant subsystems.
6. TSIs related to information and communication systems shall take into account open source and open data architecture requirements.
7. The application of the modules for conformity assessment of interoperability constituents and subsystems, including possible revisions of the content of the relevant chapters of the TSIs as well as the need for new or revised ad-hoc modules or the migration towards the standard modules set out in Annex II to Decision No 768/2008/EC of the European Parliament and of the Council shall be clarified. To that purpose a study shall be carried out which shall set out:
((i)) the roles and responsibilities of the stakeholders involved in the conformity assessment procedures;
((ii)) an extended scope to include also the conformity assessment procedures related to notified national technical rules;
((iii)) the elements of the procedures referred to in point (ii), including the content of the technical file, and the sequencing of the assessment stages;
((iv)) the templates of certificates of verification and their period of validity in the case of certification according to the relevant TSI or to the national rules;
((v)) the conditions under which interoperability constituents may be certified according to repealed TSIs;
((vi)) the elements of the surveillance and the renewal audits where assessment based on quality management system(s) apply, including the conditions under which unexpected visits of the premises of the applicant shall be carried out.
