Interoperability & safety

The creation of an integrated European railway area also calls for improved “interoperability” – or technical compatibility - of infrastructure, rolling stock, signalling and other subsystems of the rail system, as well as less complex procedures for the authorisation of use of rolling stock across the European Union's rail network.

Over the years national rail networks have developed different technical specifications for infrastructure. Different gauge widths, electrification standards and safety and signalling systems all make it more difficult and more costly to run a train from one country to another. Specific EU legislation exists to promote interoperability and overcome such differences.

The European Railway Agency plays a central role in promoting interoperability and harmonising technical standards, a process in which cooperation between EU Member States and rail stakeholders is essential.

THE EUROPEAN RAILWAY AGENCY : Promoting safety and interoperability

The European Railway Agency (ERA) based in Lille/Valenciennes, France, helps to build an integrated European railway area by reinforcing rail safety and promoting interoperability. Set up in 2006, ERA develops common technical specifications and common approaches to safety, working closely with stakeholders from the rail sector as well as with national authorities, the EU institutions and other interested parties. Featuring a dedicated Safety Unit, ERA also monitors and reports on rail safety in the EU.

The Commission made in 2010-2011 an evaluation of the implementation of Regulation (EC) No 881/2004 establishing the European Railway Agency, with help of external consultants.  The stakeholder consultation was an important part of this process; its results were presented at a public seminar on 10 December 2010.

The evaluation was overall positive, with few areas for improvement and the conclusions were used in the subsequent work on new ERA Regulation (COM(2013)27 ).


Notif-IT (Notifications using Information Technology) is a web-based application developed by the European Commission (DG MOVE) in cooperation with the European Railway Agency for the benefit of the Member States, the industry and the public.

From 1 June 2010, national railway safety and technical rules should be notified to the Commission via Notif-IT. The Commission will evaluate the notifications and publish the notified rules in this database.

Notif-IT will increase the transparency and understanding of national requirements to all stakeholders. This will contribute to the achievement of the Community objectives for developing railway transport and making the national railway systems more interoperable.
