Work Program for ERTMS:

“The Agency shall establish its role as the system authority for the ERTMS specifications , ensuring:

the management of the process for handling, assessment and eventual incorporation of changes that might be required by technical, operational or safety reasons;

the configuration control of the reference baselines, ensuring the quality and completeness of the ERTMS specifications”

ERTMS -The role of the Agency


Directives

(EC)

TSIs

(Agency)

EN standards(CEN, CENELEC, ETSI)

National Standards

Railway Interoperability Directives are « new

approach » Directives.

Council resolution, 1985 :Legislative harmonisation limited to essential

requirements to be met if products are to benefit

from free movement within the Community

Technical specifications to enable products to

meet the essential requirements are laid down in

‘harmonised’ standards, non mandatory

Compliance with ‘harmonised’ standards gives

presumption of conformity

Interoperability Directives add a « layer » :

Technical Specifications for Interoperability

(TSIs)

Configuration and Quality Control

ERTMS specifications are not in the Official Journal

- The Agency Website offers:

•Controlled repository of ERTMS specs agreed

by the sector

•Support to economic actors’ decisions

•Support to EC and Art. 21 legislative process

•Centralised DataBase of Change Requests


ERTMS Change Control Management

CCB:

Suppliers & Users (GSM-R + ETCS)

NB Rail & NSA

Control Group:

GSM-R + ETCS

Suppliers & Users

Ad-Hoc WG’s

Experts from railway and/or supplier

Economic Evaluation:

involved at all stages

ERA Core Team:

Cooperation with the Sector

Representatives in the Control Group and subgroups:

•CER

•EIM

•(ERFA)

•UNIFE/UNISIG

•ERTMS Users Group

•GSM-R Industry Group

In the Change Control Board also representatives from:

•National Safety Authorities

•NB Rail

Fruitful coordination with UIC: GSM-R project, Braking Curves,

FRS, …

Cooperation with the sector

Effective support and common priorities:


CCM:

1) Maintenance of current baselineError Correction and clarifications (e.g. “crash plan”

for ETCS)

2) Definition and justification of future releasesEnabling technology for improving competitiveness

of railways, ensuring protection for interoperability

investments

Vote in Art.21 Committee

Target Timetable

Presented by the ERTMS Coordinator, EC and ERA:


ERTMS context

Today,

Unified technology

Standardised functions

Defined safety requirements for subsytem

… parametrized for different signalling principles

… employed in different operational contexts

… part of overall safety assessment

Options must be carefully evaluated!


Directive 2001/16:

“interoperability ... rests on all the regulatory, technical

and operational conditions which must be met in order

to satisfy the essential requirements” (art 3-b)

• safety

• reliability and availability

• health

• environmental protection

• technical compatibility

ERTMS context


National Safety Authorities

ERTMS success:

• technical and operational interoperability

• harmonised acceptance in the Member States

National Safety Authorities role (art 16.2 Directive 2004/49):

a) authorising the bringing into service of the structural

subsystems constituting the trans-European Network …

c) supervising that the interoperability constituents are in

compliance with the essential requirements ….


Survey of safety approvals for first ERTMS

projects (result intended as input for I47)

Feasibility of specification formalisation

New Commission mandate including CCS TSIs

Cooperation with corridor coordination

NB Rail cooperation in ERTMS WG

Feedback from operational exploitation

Work in progress


ERTMS - way forward

Coordination

Multiple actors, competition, different

objectives

Resources

Financial and human resources (high

skills, specialised)
