I am traveling from Copenhagen to Stockholm to Oslo to Bergen this spring by SJ High Speed train. In reviewing the FAQ's on Rick's Trains and Rail Passes link ( https://www.ricksteves.com/travel-help/rail-faq ) it says the following:
Which iteration of my name should I use on my rail pass?
The gender, last name, whole first name, and country of residence on your rail pass must match the passport (or green card) you present when activating your pass. Middle names are not used. Passes are printed with the passholders' name(s) on them, and are not transferable to other people.
My US passport shows my last name as "Johnson Jr." Should I include the "Jr" when I order my rail pass? I am not sure how Europeans deal with suffixes.
