Replacement rail buses

Seat reservations are relatively expensive in Norway, at 80 kr (€7) on some routes.

With a first class pass, however, they’re free. Given you get free reservations (and free coffee onboard!) it can be worth looking into a first class pass. Depending on the rest of your planned travel of course.

You don’t need to activate your pass to book reservations, you just need the pass number. Book them at entur.no. In fact, as you say, it’s wise not to activate your pass in advance, in case there are any changes of plan. You can do it the day before travel if you want. I tend to wait until I’m at the station, certain that the train is on time etc.

WIth replacement buses, I don’t know how to book reservations, sorry. I don’t know if they show in Entur? But they should generally have enough buses to meet demand.

Accommodation - I tend to make refundable reservations, which doesn’t usually cost that much extra. If yours are non-refundable, then I guess you have to make the trains fit what you've booked! 

I doubt the replacement buses need a reservation in Norway. But you can check on entur.no.

Thank you for your replies everyone. I’ve taken your advice and booked reservations on entur.no. Apart from activating my pass, is there anything else I need to do before we go? I assume I don’t need to do anything on the rail planner app regarding seat reservations, seeing as I’ve already booked them on Entur? 

Thanks!

Correct. Just add the trains to Rail Planner, and show the reservations separately when asked.
