@IngaLovinde even if I were to buy individual tickets for all 3 rail companies (DSB, Skånetrafiken, Vy) when I visit my girlfriends in Oslo, it is still so much cheaper to just take a plane. I wish Scandinavian trains were cheaper. I think. Still waiting for Vy to continue operating international trains again.
@freya they should just sell multi-leg tickets for a (reasonable) unified fare.
