Under the agreement Norwegian rail infrastructure manager Jernbaneverket will study short and long-term options for the route with the support of Swedish transport authority Trafikverket.

The two ministries have also agreed to continue cooperating on the development of the Kiruna – Narvik line in the Arctic Circle, which is the principal route for export iron ore from mines in northern Sweden. A recent study by Jernbaneverket and Trafikverket recommended upgrading this route to accommodate projected growth in freight and passenger traffic.
