European Interoperability Standards
Published directives (“European law”)– 91/440: split infrastructure - operation– 95/18: operator’s licence– 95/19: slot allocation– 96/48: high-speed interoperability– 2001/16: conventional rail interoperability
Undertakings for operating trains– 2003: freight– 2008: international passenger

Standardization Process
European Directive: essential requirements
Joint representative body: AEIF– writes the Technical Specifications for Interoperability– TSIs contain assessable parameters– TSIs may call for European standards (methods…)
Notified Bodies– assess conformance based on TSIs + standards
TSIs
TSIs– per sub-system / essential requirements– parameters needed and enough to fulfil requirements– define constituents that may be assessed independently– method of assessment
• EU standard or mutual recognition of national standards• methods validated by Notified Bodies
– implementation process After approval, TSI integrates the European Directive
WG B14 : New CENELEC Standard
CENELEC (TC9X/SC9XB) anticipates needs of TSI– interoperability includes data transfer– freight needs include communication with fixed
installation
Issues for technology-based standards– TCN standards remain incomplete after more than 10
years (conformance test still on standardization phase)– Control-command (ERTMS) experience– Obsolescence management
WG B14: Guidelines
A survey group has been set to propose guidelines– Non-technology-based standard will be proposed
WG B14 first tasks– set data dictionary (attached to TSI reference model)– set rules for functional standardization
After agreement of SC9XB– functions in freight traffic– functions in passenger traffic– train-to-ground communications
Conclusions
WG B14 shall define non-technology-based EN (set of) standard(s) for conventional rail interoperability“(RA) Rolling Stock – Intercommunication between
vehicles and train/wayside.”
