Article 19 — Capacity model

1. The infrastructure manager shall establish a capacity model that refines the capacity strategy on the basis of the outcome of the consultation with operational stakeholders referred to in Article 15 and the consultation and coordination activities referred to in Article 16, including in the form of the capacity needs announcement referred to in Article 14(4), point (c). The capacity model shall support a balanced consideration of the capacity needs of different segments of rail transport services and of infrastructure managers’ needs to maintain, renew and develop rail infrastructure, including the upgrade of existing and construction of new railway infrastructure. It shall serve as a basis for communication, consultation and coordination of strategic capacity planning between the operational stakeholders. 2. The capacity model shall contain the information listed in Section 1 of Annex I. Infrastructure managers shall prepare and publish the capacity model for each working timetable period and update the capacity model when needed in accordance with the schedule set out in Section 2 of Annex I. The obligation to update the capacity model shall not apply if the capacity supply plan for the same working timetable period has been published. 3. The infrastructure manager shall have the right, within reasonable limits, to propose a capacity model that differs from the input received in the consultation with applicants. The infrastructure manager shall set out the applicable limits in its network statement. ENIM shall develop guidelines on those limits and include them in the European framework for capacity management. 4. Where the infrastructure manager cannot prepare a capacity model within the limits referred to in paragraph 3 of this Article, it shall partition capacity on that element of railway infrastructure in accordance with Article 27. 5. Where relevant, infrastructure managers shall coordinate in accordance with Article 16 to ensure that the outcomes of capacity partitioning are consistent and to ensure seamless multi-network services. 6. Infrastructure managers shall document and, where relevant, justify any substantial divergence between the capacity model and the capacity strategy concerning the same working timetable period.
