Hello!
I understand that to travel from Milano Centrale to Grindelwald, we can take the train EC 52 from Milano Centrale to Spiez and before transferring to another train to Interlaken then Grindelwald.
From what we have found out so far, the train EC 52 changes from being an Italian train to becoming a Swiss train at Domodossola. Is that true?
If the above is true, then do we just need to purchase the train ticket from Milano Centrale to Domodossola and the rest of the journey to Spez is covered by the Swiss Travel Pass?
Thank you!
