  "text": "An interoperable infrastructure may be used for the movement of trains not compliant with the requirements of this TSI, according to Article 5(4) of Directive 96/48/EC, provided this does not create prejudice to the fulfilment of essential requirements.\nSuch trains may use a class B signalling infrastructure, if existing. ERTMS/ETCS also offers the possibility of sending information for an on-board class B apparatus via class A track-to-train communication. If this solution is applied, in any case full ERTMS/ETCS functionality shall be installed trackside and the corresponding information shall be sent to the trains, to allow movement of interoperable trains. Trains equipped with on-board class B systems modified to receive information from class A track-to-train communication may not be declared interoperable.",
