Authorisations of railway vehicles in Member States are based on TSIs and National Technical Rules. Both complement each other e.g. for TENS National Technical Rules apply in specific cases and open points, for off-TENS more and more Member States substitute National Technical Rules by requirements defined by TSIs.
To analyse, compare, evaluate and categorise the National Technical Rules Article 27 of Directive 2008/57/EC allocates the setting up and maintenance of the “Reference Document” to the Agency. The Technical Evaluation Sector took up this task to collect, categorise and publish the “Reference Document” in close co-operation with the respective National Safety Authorities.
In addition the Technical Evaluation Sector publishes the technical rules applied by Member States and supports the European Commission in the evaluation of national technical rules notified through NOTIF-IT.
