TSIs development  
 

The first set of technical specifications for interoperability (TSI) related to infrastructure, energy, rolling stock, control-command and signalling, maintenance and operation, prepared by the European Association for Railway Interoperability (AEIF), was adopted in 2002 for the trans-European high speed rail system. These TSIs were revised in 2008.

The first priority Conventional Rail (CR) TSIs related to freight wagons, telematic applications for freight, control-command and signalling, noise emitted by rolling stock, and traffic operation and management were adopted in late 2004 and mid-2005. The TSIs related to safety in railway tunnels and accessibility for persons with reduced mobility were adopted by the Commission decisions in 2007 and entered into force on 1 July 2008. These two TSIs are applicable for both high speed and conventional rail systems.

Until the end of 2009 the Agency drafted the Conventional Railways (CR) TSIs related to infrastructure, energy, locomotives and passenger rolling stock, as well as telematic applications for passenger services. The Agency also completed the revision of the TSI related to operation and traffic management for conventional rail system. Also a limited revision of the TSI related to noise emitted by rolling stock was completed by the Agency. The four new and two revised TSIs were adopted by the Commission in 2011.
As an intermediate step, amendments of the conventional freight wagon and operation TSIs, facilitating the traffic across borders under the so-called ‘mutual recognition of authorisation’ of the freight wagons, were adopted by the Commission in 2009.

The TSI related to freight wagons was then substantially revised, including the extension of its scope to entire Community’s rail system, and was adopted by the Commission in 2013.

The recent activities of the Agency, related to TSIs, were linked with the revision of the other existing TSIs with an aim of extending their scope to the entire Community’s rail system, and where appropriate, merging TSIs related to high speed and conventional rail into a single TSI for each subsystem. The new, merged TSIs, related to locomotives and passenger rolling stock, noise, energy, infrastructure, safety in railway tunnels and persons with reduced mobility, were adopted by the Commission in 2014 and entered in force on 1 January 2015. See also the section  ‘Extension of the geographical scope of TSIs’.

The links to all the TSIs are provided here. An overview of the chronology of all TSIs (including the repealed ones) with respective links is given in the chronology table (see link at the right hand side of this page).

 

Following the adoption of the technical pillar of the 4th Railway Package, the Delegated decision (EU) 2017/1474 sets out the common and specific objectives of all TSIs to be developed or amended with a view to harmonising them and streamlining the EU railway legislation. In accordance with these objectives, in 2017 the mandate was issued by the Commission for the drafting, adoption and review of technical specifications for interoperability (TSIs)”
