Question referred

Where an inland port — which forms part of the core network — is already connected to the road and to the rail network, does Article 15 of Regulation (EU) No 1315/2013 of the European Parliament and of the Council of 11 December 2013 on Union guidelines for the development of the trans-European transport network and repealing Decision No 661/2010/EU, (1) construed in isolation or in conjunction with other provisions of that regulation, lay down an obligation to keep and to maintain both those links or an obligation to refrain from removing one of them, even merely by failing to maintain it?
