ANNEX
Procedure for demonstrating the level of compliance of existing railway lines with the basic parameters of the
technical specifications for interoperability
1. Introduction
1.1. Technical Scope
This procedure concerns the following subsystems of the Union rail system:
(a) the infrastructure structural subsystem; and
(b) the energy structural subsystem.
These subsystems are included in the list of subsystems in Annex II (1) to Directive 2008/57/EC.
1.2. Geographical Scope
The geographical scope of this procedure is the Union rail system as determined by Directive 2008/57/EC.
1.3. Definitions
For the purpose of this procedure:
(a) ‘EI’ means existing infrastructure (fixed installations) placed in service before the entry into force of Directive
2008/57/EC or lines placed in service after the entry into force of Directive 2008/57/EC without being subject to
the EC verification procedure;
(b) ‘EI demonstration of compliance’ means the verification whether basic parameters of a subsystem or/and an
element of existing lines comply with requirements of the relevant TSIs;
(c) ‘EI certificate of demonstration’ means the document issued by an independent assessor as a result of the EI
demonstration of compliance;
(d) ‘EI declaration of demonstration’ means the document issued by an applicant after receiving EI certificate of
demonstration.

lines
2.1. Purpose
According to Decision 2011/275/EU concerning a technical specification for interoperability relating to the ‘infra
structure’ subsystem of the trans-European conventional rail system, existing lines that are not subject to a renewal
or upgrading project may allow the circulation of TSI-conform vehicles whilst meeting the essential requirements of
Directive 2008/57/EC.
Therefore, the following procedure may be applied for demonstrating compliance of existing fixed installations with
the relevant TSIs without being subject to a new authorisation for putting into service.
It is not mandatory, but may be used on a voluntary basis.
2.2. Procedure for demonstration of the level of compliance with the basic parameters of the TSI
1. Procedure for demonstration of the level of compliance with the basic parameters of the TSI is the EI demon
stration of compliance procedure whereby the applicant fulfils the obligations laid down in points 2,3,5.2 and
5.4, and ensures and declares on his sole responsibility that the subsystem concerned, which has been subject to
the provisions of point 4, satisfies the requirements of the relevant TSI(s).

2. The
applicant
lodges
an
application
for
the
EI
demonstration
of
compliance
of
the
subsystem
with
an
inde
pendent assessor of his choice.
The application includes:
(a) name and address of the applicant and, if the application is lodged by the authorised representative, his
name and address as well;
(b) the technical documentation.
3. Technical
documentation
3.1. The applicant establishes the technical documentation and makes it available to the independent assessor
referred to in point 4. The documentation should make it possible to demonstrate the level of compliance
of the existing subsystem's with the basic parameters of the relevant TSI(s).
3.2. The technical documentation contains, wherever applicable, the following elements:
(a) general description of the existing subsystem;
(b) the documents necessary for the compilation of the technical file;
(c) a list of the harmonised standards and/or other relevant technical specifications the references of which have
been published in the Official Journal of the European Union and/or national technical specifications which are
notified under Article 17(3) of Directive 2008/57/EC, applied in full or in part, and descriptions of the
solutions adopted to meet the requirements of the relevant TSI(s) where those harmonised or national
standards have not been applied. In the event of partly applied harmonised or national standards, the
technical documentation specifies the parts which have been applied;
(d) conditions for use of the subsystem (restrictions of running time or distance, wear limits, etc.);
(e) descriptions and explanations necessary for the understanding of the operation and maintenance of the
subsystem;
(f) conditions for maintenance and technical documentation regarding the maintenance of the subsystem;
(g) any technical requirement specified in the relevant TSI(s) that have to be taken into account during main
tenance or operation of the subsystem;
(h) other appropriate technical evidences, which demonstrate that previous checking or tests have been
successfully performed, under comparable conditions, by competent bodies.
3.3. The applicant keeps the technical documentation at the disposal of the relevant national authorities throughout
the service life of the subsystem.
4. Procedure for demonstration of the level of compliance with the basic parameters of the TSI.
4.1. The independent assessor chosen by the applicant takes into account evidence of examinations, checks or tests
that have been performed by other bodies or by the applicant.
4.2. The evidences gathered by the independent assessor should be suitable and sufficient to demonstrate the level of
compliance with the requirement of the relevant TSI(s) and that all required and appropriate checks and tests
have been carried out.
4.3. Where the existing subsystem meets the requirements of the relevant TSI(s), the independent assessor issues an
EI certificate of demonstration.
5. EI
declaration
of
demonstration
5.1. The applicant draws up a written EI declaration of demonstration for the subsystem and keeps it throughout
the service life of the subsystem. The EI declaration of demonstration identifies the subsystem for which it has
been drawn up.

5.2. The EI declaration of demonstration and the accompanying documents is written in accordance with
Chapter 2.5.
5.3. A copy of the EI declaration of demonstration is made available to the relevant authorities upon request.
6. Technical
file
6.1. The independent assessor is responsible for compiling the technical file that accompanies the EI declaration of
demonstration.
6.2. The technical file accompanying the EI declaration of demonstration is lodged with the applicant.
6.3. The applicant keeps a copy of the technical file throughout the service life of the subsystem; it is sent to any
other Member State which so requests.
