Some travel companions and I are planning to take a train from Oslo to Bergen Norway in the first week of August. Now (1½ months in advance) prices are around 500 NOK per person for a daytime train at that time.
Do these tickets tend to increase in price as the date gets closer and therefore it behooves us to book in advance? Or do they tend to stay steady so we can book at the last minute for the same price (e.g. contingency if our incoming flights are delayed)?
Anecdotally, I feel that Italian train tickets are steady til date of travel but German trains tend to increase. How's Norway work?
