Notifications
Article 3
1. Once ERTMS is put into operation on a core network corridor section, the Member State concerned shall notify the Commission of that fact within one month, through the systems established under Article 49(1) of Regulation (EU) No 1315/2013 and Article 5(1) of Commission Implementing Decision 2014/880/EU ( 8 ) . 2. Member States shall notify the Commission of any delays in putting ERTMS in operation on a given core network corridor section to be equipped. The railway infrastructure managers shall inform the Member States about those delays accordingly. 3. When notifying the delays referred in paragraph 2, the Member State concerned shall send to the Commission a file containing a technical description of the project and specifying a new date for putting ERTMS into operation. The file shall specify the causes for the delay and shall indicate the corrective measures taken by the railway infrastructure manager. 4. If the delay results from an exceptional circumstance, the Commission may accept to postpone the relevant date by a maximum of three years. If a postponement is granted, the Member State shall make the necessary amendments to its national implementation plan as referred to in point 7.4.4 of the Annex to Regulation (EU) 2016/919 within one month of granting that postponement. Exceptional circumstance referred to in the first subparagraph means a circumstance resulting from the planning phase and which is related to specific geological findings, environmental or species protection, archaeological finds, permitting procedures, implementation of an environmental impact assessment pursuant to Directive 2014/52/EU of the European Parliament and of the Council ( 9 ) ; or a circumstance resulting from the construction and authorisation phases that are out of the control of the project promoter and do not fall into the category of the usual risks that should be addressed at project management level in this type of projects. 5. If ERTMS specifications set out in Regulation (EU) 2016/919 are changed by legislative act in an incompatible way the Member States shall provide the Commission with an analysis of the impact of the application of the modified legal reference on their network and on the ERTMS planning without unreasonable delay, but at latest at the time of the formal opinion of the Committee referred to in Article 51 of Directive (EU) 2016/797. If a direct impact of the changes can be demonstrated in terms of cost or timeline for specific implementations, Annex I shall be adapted accordingly.
