My wife and I are traveling from Oslo to Flam in late June. I'm trying to book my train on nsb.no. it allows me to get everything set but when I enter my credit card info it says 'Transaction failed'. I spoke with my credit card, tried a different card, tried it on 2 different computers, no luck, same message. Then I saw something that says you can't book online within 90 days (in other words it's only for booking 4 months or more out)???
Any suggestions? FYI, I sent nsb.no an email a week ago and have received nothing back. :--(
