ANNEX II

SUBSYSTEMS 1. For the purposes of this Directive, the system constituting the trans-European high-speed rail system may be broken down into subsystems, as follows: 1.1. basically structural areas: infrastructures energy control and command and signalling rolling stock; 1.2. basically operational areas: maintenance environment operation users. 2. For each subsystem, the list of aspects relating to interoperability is indicated in the order given to the representative joint body for drawing up draft TSIs. Under the provisions of Article 6 (1), this order shall be established in accordance with the procedure laid down in Article 21 (2). Where necessary, the list of aspects relating to interoperability indicated in the order is specified by the representative joint body in accordance with the provisions of Article 5 (3) (e). 3. Within the meaning of Article 5 (3) (b), the following are regarded as basic parameters for achieving interoperability: BASIC PARAMETERS Minimum infrastructure gauges Minimum radius of curvature Track gauge Maximum track stressing Minimum platform length Platform height Power-supply voltage Catenary geometry ERTMS characteristics (1*) Axle loading Maximum train length Gauge of rolling stock Minimum braking characteristics Boundary electrical characteristics of rolling stock Boundary mechanical characteristics of rolling stock Operating characteristics linked to train safety Boundary characteristics linked to outside noise Boundary characteristics linked to outside vibrations Boundary characteristics linked to outside electromagnetic interference Boundary characteristics linked to inside noise Boundary characteristics linked to air conditioning Characteristics linked to the carriage of disabled persons. (1*) European Rail Traffic Management System.
