CHARACTERISATION OF THE SUBSYSTEM4.1. Introduction(a) The European Union rail system, to which Directive 2008/57/EC applies and of which the subsystemsare parts, is developed to become an integrated system for which the consistency must be verified.14
(b) This consistency has been checked in relation to the development of the specifications within thisTSI, its interfaces with respect to the systems in which it is integrated and also the operating rules forthe railway.(c) Taking account of all the applicable essential requirements, the basic parameters related to safety inrailway tunnels are set out for the subsystems infrastructure, energy and rolling stock in section 4.2 ofthis TSI. The operational requirements and responsibilities are set out in the OPE TSI and in section 4.4of this TSI.4.2. Functional and technical specifications of the subsystems(a) In the light of the essential requirements in Chapter 3, the functional and technical specifications ofthose aspects specific to tunnel safety in the above-mentioned subsystems are as follows:4.2.1. Subsystem Infrastructure4.2.1.1. Prevent unauthorised access to emergency exits and technical roomsThis specification applies to all tunnels.(a) Unauthorised access to technical rooms shall be prevented.(b) Where emergency exits are locked for security purposes, it shall always be possible to open themfrom inside.4.2.1.2. Fire resistance of tunnel structuresThis specification applies to all tunnels.(a) In the event of fire, the integrity of the tunnel lining shall be maintained for a period of timesufficiently long to permit self-rescue, evacuation of passengers and staff and intervention of emergencyresponse services. That period of time shall be in accordance with the evacuation scenario and reportedin the Emergency Plan.(b) In the cases of immersed tunnels and tunnels which can cause the collapse of importantneighbouring structures, the tunnel main structure shall withstand the temperature of the fire for aperiod of time allowing evacuation of the endangered tunnel zones and neighbouring structures. Thisperiod of time shall be reported in the emergency plan.4.2.1.3. Fire reaction of building materialThis specification applies to all tunnels.(a) This specification applies to construction products and building elements inside tunnels.15
