Technical specifications for interoperability  
 
Technical specifications for interoperability (TSIs) mean the specifications by which each subsystem or part of subsystem is covered in order to meet the essential requirements and to ensure the interoperability of the European Community's high speed and conventional rail systems. The development of TSIs is one of the basic tasks of the Agency.The Agency performs the revision of existing TSIs, keeps them up to date, and supports the sector in their application by issuing application guides and by dissemination and training actions. When necessary, ERA may also draft new TSIs, based on a mandate from the Commission.Links to all TSIs including their accompanying documents and previous versions are to be found on the right hand side of this page. An overview of the chronology of all TSIs (including the repealed ones) with respective links is given in the chronology table.For drafting and revising TSIs, the Agency establishes working parties with experts from the European Representative Bodies of the Railway sector (RBs) and the National Safety Authorities (NSAs). In certain cases the organisations of social partners, freight customers and passengers are consulted before the ERA recommendations is submitted to the Commission. The full TSI drafting procedure is presented on the image below.
