# 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 4.3.3.2: Track-side Control Command Equipment

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

Track-side subsystems transmission equipment (GSM-R, Euroloop, Eurobalise) must be positioned so that reliable data communication is assured at the extremes of the track geometry capable of being traversed by the rolling stock. The movement and behaviour of the rolling stock shall be taken into account. See section 4.2.5 (ETCS and EIRENE air gap interfaces).
The positioning of Marker Boards (see section 4.2.16) and other trackside control command equipment (e.g. GSM-R antennas, Euroloops, Eurobalises, HABD, light signals, point machines,….) has to cope with the requirements (minimum infrastructure gauge) defined in the TSI Infrastructure.
This interface is relevant, in regard to data communication, to Class A system. Equivalent requirements for Class B systems are defined by the appropriate Member State (see Annex B).
TSI Infrastructure HS: Section 4.2.3
