If you are going from Germany to Sweden and Norway you need a global pass. 

Thank you very much, AnnaB.

As the reply here is very specific, yet if people who do their due diligence and search for the topic, will find this post, I’ll ad that if you have a one country pass for Sweden, you can buy a seat reservation to Riksgränsen station and get a normal ticket to Narvik.

This a generally good advice, I am basically using the same trick to not use a home bound/outbound travel day by going to Narvik. My home country is Norway.

You can also do this if you want to have a break/sleepover on your home bound/outbound journey. I usually buy tickets to/from Ed and have a stop in Oslo on my way to from Bergen/Göteborg.
