I have been to Lucerne as well as Interlaken in Switzerland. I am planning to visit Innsbruck in Austria. I love Alps and nature that I saw in Switzerland.
I see that similar to Golden Pass Line, Innsbruck has a scenic train. Also, I see some Alps, cable car, etc. in Innsbruck which I have already seen in Switzerland.
Is Innsbruck any different from Lucerne and/or Interlaken?
