The reason is the weather conditions, which have been extremely extreme with large amounts of snow and wind at the same time, says Lina Edström at SJ's press department.
Neither the Swedish Transport Administration nor we think it's a good idea to operate passenger trains on that stretch.
SJ's customers have been informed about the cancelled departures and have been given the option to rebook their journey or cancel and get their money back.
No replacement buses have been put in place - also due to the weather conditions.
We absolutely do not want to put passengers on buses in this kind of weather, says Lina Edström.
SJ cannot provide an exact update on when the traffic will be up and running again, but based on the current weather forecasts, the night trains departing on Sunday evening will be able to run, according to Lina Edström.
There will be extra carriages where we will be able to take passengers who may have been stranded in Narvik, for example.
