On August 10 2015 SJ replaced the two daily Stockholm - Oslo Inter-City services with three X2000 services, reducing the journey time for the 572km trip from 5h 38min to around four-and-a-half hours with intermediate stops at Karlstad and Arvika.

Between August 10 2015 and May 31 2016 passenger numbers rose by 39% between Stockholm and Oslo and increased by 76% on the Karlstad - Oslo section of the route.

SJ says it is now working to increase the frequency of Stockholm - Oslo X2000 services.
