The development of TEN-T and the major Core Network Corridors (CNC) for transport in EU is expected to render improved transport connections based on harmonized transport-system standards across national borders. This is understood as an important basis for businesses to flourish and expand. In order to develop CNCs, a framework for governance of these was set out in the EU regulation. Each CNC is implemented with the help of a coordinator ap-pointed by the European Commission. Corridor forums are held with state representatives and other stakeholders, mainly geographically located on the corridor. In addition working groups are being formed for specific topics. Even with these supporting structures being implemented the question of stakeholder participation still is a tricky one. Considering that the CNCs include road, rail, air and water transports as well as both passenger and goods transports, it is easy to realize that the number of stakeholders is high, stretching across several countries and border crossings. In addition to this there are different challenges if you are ge-ographically located on the corridor, as compared to being located in the corridors´ catchment area or more peripheral areas. The main question set out to investigate in an inter-view study financed by the Swedish Transport Administra-tion is to monitor experiences from cooperation in this situ-ation and to analyse whether there is need for complemen-tary governance structures to develop the CNCs.
