To support on technical matters the implementation of the European Community legislation on Railways in the field of interoperability.

The main tasks of the Interoperability Unit are:

  • Managing the issues related to infrastructure, energy, rolling stock, telematic applications, and traffic operation and management subsystems, including drafting recommendations to the European Commission for update and revision of the Technical Specifications for Interoperability (TSIs) and publication of applicable national rules.
  • Collaboration with international organisations (OTIF, OSJD).
  • Coordination of TSI-related activities with the European Standardisation Bodies (CEN/CENELEC, ETSI), the Notified Bodies (NB-Rail) and National Safety Authorities (NSA).
  • Setting up and maintenance of infrastructure- and vehicle-related registers which support railway interoperability through transparency .
  • Activities related to vocational competences on common uniform criteria and the assessment of staff involved in the operation and the maintenance.

Sector involvement
In order to fulfil these tasks the Interoperability Unit establishes working parties with experts from European Representative Bodies of the Railway sector (RBs), the Intergovernmental Organisation for International Carriage by Rail (OTIF) and National Safety Authorities (NSAs). In certain cases the organisations of social partners, freight customers and passengers are consulted before the Agency deliverables are submitted to the Commission. The full procedure is presented on the image below.

The Interoperability unit is devided into four sectors:

  • Rolling Stock Sector, which is responsible for all the issues related to the vehicles, including drafting and revising technical specifications for interoperability.
  • Fixed Installations Sector, which is responsible for all the issues related to the energy and infrastructure subsystems, including drafting and revising technical specifications for interoperability.
  • Operational Sector, which is responsible for drafting and revising the TSIs on telematics applications and on operation and traffic management.
  • Conformity Assessment, Registers and Standards Sector, which is responsible for the conformity assessment, setting up and maintaining interoperability registers, collaboration with European standarisation organisations and OTIF and for monitoring railway interoperability.
