thoguh this is later, it may help for similar Qs;
Nor-way is only a long-distance BUs (UK they say coach) operator.
ALL norway buses/trains and what they have are in the national route planner on www.rutebok.no
Like any normally advanced western country (that means excl. the UK, and also FR) there is a national govmt. run routeplanner for any means of public transport. You should be able to find any busroute or whatever in this.
