"Night train traffic to and form northern Sweden and Norway plays a vital role for both domestic and international travellers. Demand is exceptionally high, and it is growing," said SJ CEO Jonas Abrahamsson in a statement.
The agreement ensures daily return journeys on the Stockholm-Narvik and Stockholm-Umeå routes, offering couchette and sleeper cabins without the need for any train changes.
It means that people travelling from Stockholm to Narvik in Norway (as well as Kiruna and Abisko among other places) will no longer have to change trains in Boden.
SJ has been operating the night trains since December 2024. Prior to that, the Norwegian operator Vy Tåg held the contract for the routes.
