the following text is added at the end of section 1.1:

‘This TSI is applicable to control-command and signalling track-side Subsystems of the rail network defined in the section 1.2 (Geographical scope) of this TSI and to the control-command and signalling on-board subsystems of vehicles which are (or are intended to be) operated on it. These vehicles are of one of the following types (as defined in Annex I sections 1.2 and 2.2 to Directive 2008/57/EC):

The TSI shall apply to networks with 1 435 mm, 1 520 mm, 1 524 mm, 1 600 mm and 1 668 mm track gauges. However, it shall not apply to short border crossing lines with 1 520 mm track gauges that are connected to the network of third countries’

in the table of section 4.1, ‘4.2.1’ is added to the basic parameters related to control-command and signalling track-side subsystem, part train protection and ‘4.2.1.2’ is added to the basic parameters related to control-command and signalling on-board subsystem, part radio communication, and to control-command and signalling track-side subsystem, part radio communication;

(e)

the text of section 4.2.1.2 is replaced by the following text:

‘4.2.1.2.   Availability/Reliability

This section refers to the occurrence of failure modes not causing safety hazards but creating degraded situations, the management of which could decrease the overall safety of the system.

In the context of this parameter, “failure” means the termination of the ability of an item to perform a required function with the required performance and “failure mode” means the effect by which the failure is observed.

To ensure that the relevant infrastructure managers and railway undertakings are given all the information they need to define appropriate procedures for managing degraded situations, the technical file accompanying the EC declaration of verification for an on-board or track-side CCS subsystem shall contain the calculated availability/reliability values related to failure modes having an impact on the capability of the CCS subsystem to supervise the safe movement of one or more vehicles or to establish radio voice communication between traffic control and the train drivers.

Compliance with the following calculated values shall be ensured:

To allow the infrastructure managers and railway undertakings to monitor, during the life of the subsystems, the level of risk and the respect of the reliability/availability values used for the definition of procedures to manage degraded situations, the requirements for maintenance stated in Section 4.5 (Maintenance rules) shall be respected’

the second row of the table in section ‘4.3.2 Interface to the rolling stock subsystem’ is amended as follows:

the following text is added at the end of section 6.1.1:

‘With regard to checking if essential requirements are fulfilled through compliance with the basic parameters, and without prejudice to the obligations set out in Chapter 7 of this TSI, control-command and signalling interoperability constituents and subsystems that do not implement all functions, performance and interfaces as specified in Chapter 4 (including the specifications referred to in Annex A), can obtain EC certificates of conformity or, respectively, EC certificates of verification, under the following conditions for issuing and using the certificates:

If some essential requirements are fulfilled by national rules or if a control-command and signalling interoperability constituent or subsystem does not implement all functions, performance and interfaces specified in this TSI, the provisions of section 6.4.2 shall apply.’

(h)

the text of the third paragraph of section 6.1.2 is amended as follows: in subparagraph 2 ‘See Annex A 4.2.2c’ is deleted and in subparagraph 3 ‘unless otherwise specified in Annex A 4.2.2c’ is deleted;

the text of section 6.4 is replaced by the following:

‘6.4   Provisions in case of the partial fulfilment TSI requirements

6.4.1.   Assessment of parts of control-command and signalling subsystems

Pursuant to Article 18(5) of the Railway Interoperability Directive, the notified body may issue certificates of verification for certain parts of a subsystem, if allowed to do so under the relevant TSI.

As pointed out in section 2.2 (Scope) of this TSI, the track-side control-command and signalling subsystem contains three parts, while the on-board control-command and signalling subsystem contains two parts, specified in section 4.1 (Introduction).

A certificate of verification may be issued for each part specified in this TSI; the notified body only checks if that particular part fulfils the TSI requirements.

Regardless of which module is chosen, the notified body shall check that:

6.4.2.   Control-command and signalling subsystems' partial fulfilment of the requirements due to limited application of the TSI

If some essential requirements are fulfilled by national rules, the EC certificate of conformity for an interoperability constituent and the EC certificate of verification for a subsystem shall make precise reference to the parts of this TSI whose conformity has been assessed and the parts whose conformity has not been assessed.

If an interoperability constituent does not implement all functions, performance and interfaces specified in this TSI, an EC certificate of conformity may only be issued if the unimplemented functions, interfaces or performance are not required to integrate the interoperability constituent into a subsystem for the use indicated by the applicant, for example (*1):

The EC certificate of conformity (or accompanying documents) for the interoperability constituent shall fulfil all the following requirements:

If a control-command and signalling subsystem does not implement all functions, performance and interfaces of this TSI (e.g. because they are not implemented by an interoperability constituent integrated into it), the EC certificate of verification shall indicate which requirements have been assessed and the corresponding conditions and restrictions on the use of the subsystem and its compatibility with other subsystems.

In any event, notified bodies shall coordinate with the Agency the way in which conditions and limits of use of interoperability constituents and subsystems are managed in the relevant certificates and technical files in the working group set up under Article 21a(5) of Regulation (EC) No 881/2004 of the European Parliament and of the Council (*2).

6.4.3.   Intermediate Statement of Verification

If conformity is assessed for parts of subsystems specified by the applicant and different from the parts allowed by section 4.1 (Introduction) of this TSI, or if only certain stages of the verification procedure have been performed, only an intermediate statement of verification may be issued.

(*1)  The procedures described in this Chapter do not prejudice the possibility of grouping constituents together."

New vehicles authorised to be placed in service for the first time shall be equipped with ERTMS in line either with the set of specifications # 1 or the set of specifications # 2 listed in Table A2 of Annex A.

From 1 January 2018, new vehicles authorised to be placed in service for the first time shall be equipped with ERTMS only in line with the set of specifications # 2 listed in Table A2 of Annex A.

The requirement to be equipped with ERTMS does not apply to new mobile railway infrastructure construction and maintenance equipment, new shunting locomotives or other new vehicles not intended for high speed service, if they are intended exclusively for national service operated outside the corridors defined in section 7.3.4 and outside the lines ensuring the connections to the main European ports, marshalling yards, freight terminals and freight transport areas defined in section 7.3.5, or if they are intended for off-TEN cross-border service, i.e. service until the first station in the neighbouring country or to the first station where there are connections further in the neighbouring country.

It is mandatory to fit ERTMS/ETCS on-board existing vehicles if installing any new train protection part of a control-command and signalling on-board subsystem on existing vehicles intended for high-speed service
