Division 4.2.1.3 Infrastructure interfaces

The infrastructure installation shall ensure that:

1. (a)

   the train detection system respects the requirements quoted in 4.2.1.2(B), above;

2. (b)

   the position of the antennae of the trackside subsystems is such 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 tock shall be taken into account. By definition, the communication antennae at the trackside shall not infringe the network's structure gauge. The respect of the structure gauge requirement of the European high-speed network is a matter for the infrastructure manager.
