Joint Network Secretariat (JNS)

The JNS (Joint Network Secretariat) procedures aim at EU-wide harmonisations of any action taken after any issue, e.g. accidents or incidents in railways in the EU.

The JNS (Joint Network Secretariat) procedures aim at EU-wide harmonisations of any action taken after any issue, e.g. accidents or incidents in railways in the EU.

Any railway stakeholder can submit a request for a JNS procedure to the JNS-panel using the notification form indicating which kind of procedure is intended.

The JNS rules distinguish between an urgent and a normal procedure:

  • The purpose of the urgent procedure is to develop EU-wide harmonised short-term risk mitigation measures to ensure mainly safety and interoperability;
  • The purpose of the normal procedure is to develop EU-wide harmonised mid- and long-term measures to finally solve the issue in an efficient and sustainable way.

The panel, consisting of ERA, together with NSA representatives and GRB representatives:

  • Decides about the admissibility of the submission;
  • Decides which procedure is chosen;
  • Suggests key issues and questions to be considered by the task force;
  • Nominates the members of the task force.

The task force consists of participants from NSAs, NIBs and GRBs which are nominated according to the competences required to solve the issue and answer questions. ERA is organising the procedure, arranging the meetings and acting as chair in the task force meetings, whilst the responsibilities assigned under applicable EU or national legislation, such as safe operation however, still remain with the respective railway actors involved.

The outcome of the task force discussions has to be submitted to the panel and, after endorsement, be disseminated in an appropriate way.
