I am having difficulty trying to reserve train travel as part of Norway in a Nutshell without actually rebuying the entire tour ( I already have the Scandinavian train pass). I have had trouble in reaching NSB to reserve train travel the way Rick Steves outlines in his book. Any suggestions.
If the Norwegian Rail phone numbers on p. 296 of the latest edition aren't working for you, this is another number to try: 011-47-6105-1910.
You can also make the (most important) Oslo-Myrdal reservation through Rail Europe. Then, you'd buy the discounted and train-specific Myrdal-Flam train ticket in a train station (such as Oslo, or wherever you get your pass activated).
I was able to get through on +4761051910. They were very helpful and friendly and was able to get reservations on flamsbanna train and the other trains as well. Thanks for your help.
