Article 21 — Contingency planning

1. Infrastructure managers shall put in place and implement a continuous process of contingency planning to prepare for disruptions of network operations and for other crisis situations affecting rail traffic. Contingency planning shall provide the basis for traffic management, disruption management and crisis management in accordance with Article 44, with a view to enabling a fast reaction in such situations and to minimising their impact on rail traffic. Infrastructure managers shall document the results of their contingency planning in a contingency plan. 2. Contingency planning shall involve in particular: (a) the designation of alternative routes, where such routes exist, including on other networks, allowing traffic to be rerouted in the event of non-availability of elements of railway infrastructure included in the core and extended core TEN-T network, and of any sections and nodes covered by the strategic capacity planning documents; (b) an indicative planning of the railway infrastructure capacity available on the alternative routes designated in accordance with point (a), providing transparency about railway infrastructure capacity available on such routes, which can be utilised in the event of incidents and, in particular, network disruptions in accordance with Article 48; (c) laying down the rules and procedures for traffic and crisis management, including on the sharing of information between infrastructure managers, other operational stakeholders and other stakeholders such as public authorities in charge of rail or security and emergency response, as well as criteria for the activation of these procedures; (d) the identification and listing of bodies to be informed in the event of serious incidents or serious disruptions to train movements; (e) any other preparations necessary to perform disruption management and crisis management in accordance with Article 44 and with the European framework for the coordination of cross-border traffic management, disruption management and crisis management referred to in Article 46. 3. Infrastructure managers shall ensure the consistency of contingency planning with strategic capacity planning, in particular the capacity strategy, the capacity model, the capacity supply plan and with the planning for railway infrastructure works as referred to in Article 11. 4. The results of contingency planning, in particular the designation of alternative routes in accordance with paragraph 2, point (a), and the indicative capacity planning on alternative routes in accordance with paragraph 2, point (b), shall be included in the capacity model and in the capacity supply plan. 5. The Commission shall adopt implementing acts setting out the details of the procedure and criteria to be followed for the application of paragraph 2 of this Article, in particular for situations which have a potential impact on cross-border traffic. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 76(2).
