NB-Rail (RFU / QC)

At European level, the notified bodies are organised in an ‘NB Rail’ coordination group. The legal basis for this is the Interoperability Directive (EU) 2016/797. In this way the members

• link to the EU Commission and ERA,
• exchange experience and information,
• formulate suggestions for improvement for future TSIs and standards,
• Recommendations for use (RFU) are drawn up (see below),
• ‘Questions for clarification (QC) dealt with (see below).

Addition to RFU: The inclusion of representatives of the ERA and the EU Commission in the RFU ensures subsequent acceptance in the sector. RFUs represent a coordinated position of all parties involved and thus ensure a standardised approach to issues relating to technical topics or the certification process. This results in RFUs for fundamental topics and/or with technical reference to individual subsystems. The NB-Rail RFUs can be viewed here.

Addition to QC: Unlike the RFUs, these issues are coordinated with the involvement of other external bodies (outside NB Rail).
