How do I check in to the sleeping compartment or the rest compartment and what are the check-in and check-out times?

In Bergen, check-in takes place on the platform, and in Oslo you check in on board, in carriage 5.

Check-in times

Oslo–Bergen: 22:40
Bergen–Oslo: 22:40

We can resell your reserved place in Sleeper or Rest if you do not board the train at the station stated on your ticket and have not made yourself known to the conductor within half an hour of the train’s departure.

You may remain in your Sleeping compartment until:

Oslo–Bergen: 06:45
Bergen–Oslo: 06:45

A wake-up announcement is made over the public address system 15 minutes before it’s time to exit the train at its final stop. If you are getting off the train before the last stop, you are responsible for being ready on time to detrain at your stop.
