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”

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 » :

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)

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 ….
