Article 6 Cost modelling

By derogation to Article 3(1) and the first sentence of Article 5(1), the infrastructure manager may calculate direct unit costs by means of robustly evidenced econometric or engineering cost modelling, provided it can demonstrate to the F1Office of Rail and Road that the direct unit costs include only direct costs incurred by the operation of the train service and, in particular, do not include any of the costs referred to in Article 4. The Office of Rail and Road may request the infrastructure manager to calculate for comparison direct unit costs in accordance with Article 3(1) and Article 5(1) or by means of cost modelling in accordance with the first sentence.
