Nordic Countries - Oslo-luggage storage

There will be times in my week long visit to Norway that I don't want to lug around all of my luggage. Are there lockers at the train station? Bus stations?

I have used lockers at the train station in the past. I can't guarantee they are still there (as it was a few years ago) but I've never been to a major European rail station that did NOT have storage facilities so it's highly likely that they are still there.

Storage at OSL airport, at Oslo central train station, or you could leave it with your hotel.

Thank you very much for the information!

There is a left luggage office at the airport. ID required. It's on the ground (arrivals) floor, at the extreme end, next to international arrivals (the opposite end to the railway station). There are left luggage lockers (including lockers taking credit cards) at Oslo Sentralstasjon (close to the airport trains), and also some coin operated lockers at Nationaltheatret railway station, and at the bus terminal.

Hotels will store your luggage for the day, if you are a guest, but keep in mind that this is basically an unguarded room. No receipts issued
