# Commission Decision of 7 November 2006 concerning a technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European high speed rail system and modifying Annex A to Decision 2006/679/EC concerning the technical specification for interoperability relating to the control-command and signalling subsystem of the trans-European conventional rail system (notified under document number C(2006) 5211) (Text with EEA relevance) (2006/860/EC), Division 7.2.6: Interfaces with class B systems

Extent: E+W+S+N.I.

In every case, to support continued interoperability, Member States shall ensure that the functionality of legacy systems for radio and train protection (referred to in Annex B of the TSI), and their interfaces remain as currently specified. This requirement excludes those modifications that might be necessary to mitigate safety-related defects of these systems.
Member States shall make available the information that is required to support development and safety-certification of apparatus, to allow interoperability of Class A equipment with their legacy Class B radio and train protection facilities.
