Kravnr. TSI SRT 2014 TSI SRT 2019 Annex V Reason for the evolution
4.1 (a) The European Union rail system, to which Directive 2008/57/EC applies and of which the subsystems are parts, has been developed to become an integrated system for which the consistency must be verified. “European Union rail system” is replaced by “Union rail system” -
4.2.1.2 Fire resistance of tunnel structures

(b) In the cases of immersed tunnels and tunnels which can cause the collapse of important neighbouring structures, the main structure of the tunnel shall withstand the temperature of the fire for a period of time that is sufficient to allow evacuation of the endangered tunnel zones and neighbouring structures. This period of time shall be reported in the emergency plan.

Section 4.2.1.2 (b) is deleted. That type of risks is removed from the scope covered by the TSI. The TSI is covering the risks for passengers and on-board staff. Such risks are covered by national regulations and not in the scope of interoperability.

Simplification for the applicants.

4.2.1.3 Fire reaction of building material

This specification applies to all tunnels.

(a) This specification applies to construction products and building elements inside tunnels.

(b) Tunnel building material shall fulfil the requirements of classification A2 of Commission Decision 2000/147/EC. Non-structural panels and other equipment shall fulfil the requirements of classification B of Commission Decision 2000/147/EC.

(c) Materials that would not contribute significantly to a fire load shall be listed. They are allowed to not comply with the above.

a) This specification applies to construction products and building elements inside tunnels. These products shall fulfil the requirements of Commission Regulation (EU) 2016/364:

(1) Tunnel building material shall fulfil the requirements of classification A2.

(2) Non-structural panels and other equipment shall fulfil the requirements of classification B.

(3) Exposed cables shall have the characteristics of low flammability, low fire spread, low toxicity and low smoke density. These requirements are fulfilled when the cables fulfil at least the requirements of classification B2ca, s1a, a1.

If the classification is lower than B2ca, s1a, a1, the class of cables may be determined by the infrastructure manager after a risk assessment, taking into account the characteristics of the tunnel and the intended operational regime. For the avoidance of doubt, different classifications of cable may be used for different installations within the same tunnel provided that the requirements of this paragraph are met.

(b) Materials that would not contribute significantly to a fire load shall be listed. They are allowed to not comply with the above.

Requirement updated and moved to the Infrastructure section. Assessment is done by the NoBo for the subsystem Infrastructure and not Energy.

This specification applies to all tunnels of more than 1 km in length.

Technical rooms shall be equipped with detectors which alert the infrastructure manager in case of fire

Section 4.2.1.4 is replaced as follows:

4.2.1.4. Fire detection in technical rooms

This specification applies to all tunnels of more than 1 km in length.

(a) Fire in technical rooms shall be detected in order to alert the infrastructure manager.

The provision of fire detection devices may not be appropriate in all cases. For instance, fire detection equipment is susceptible to false alarm, and this could in itself create a safety risk.
4.2.1.5.2 (3) Alternative technical solutions providing a safe area with a minimum equivalent safety level are permitted. The equivalent level of safety for passengers and staff shall be demonstrated using the Common Safety Method on risk assessment. Section 4.2.1.5.2 (b3) is deleted This clause has been removed as it is covered by the possibility to cover all parameters relative to the essential requirement ‘Safety’ with a risk assessment.
4.2.1.5.4 Emergency lighting on escape routes

(3) Position of lights: — above the walkway, as low as possible

(c) Autonomy and reliability: an alternative power supply shall be available for an appropriate period of time after failure of the main power supply. The time required shall be consistent with the evacuation scenarios and reported in the Emergency Plan.

Point (c) is replaced as follows:

(c) Autonomy and reliability: an alternative electricity supply shall be available for an appropriate period of time after failure of the main supply. The time required shall be consistent with the evacuation scenarios and reported in the Emergency Plan.

The term “Escape routes” is deleted:

“As low as possible”: This unclear requirement is very difficult to assess.

4.2.1.5.5 (f) All doors leading to emergency exits or cross-passage shall be marked. The term "cross-passage" is replaced by "cross-passages. Correction of mistake
4.2.1.6 (a) (3) The height of the walkway shall be at top-of-rail level or higher. (3) The height of the walkway shall be at bottom-of-rail level or higher. The top of rail level resulted from errors in translations and did not reflect the actual situation. Keeping the “top of rail” requirement would have resulted in the creation of one or more specific cases.
4.2.1.7 (a) (1) The separation between tunnels in open air is longer than the maximum length of the train intended to be operated on the line + 100 m

(2) The open air area and track situation around the separation between tunnels allow passengers to move away from the train along a safe space. The safe space shall contain all passengers of the maximum capacity of the train intended to be operated on the line.

Section 4.2.1.7 is modified as follows:

(a) in point (a1) the terms "length of the train" are replaced by the terms "length of the passenger train

(b) in point (a2) the terms "safe space" are replaced by "open air area" and the terms "along a safe space" are deleted.

Freight trains carrying no passenger, they should not be considered for rules on evacuation.
