My wife and I are taking off on a morning train from Lucerne to Milan departing Lucerne at 7:18 through Arth-Goldau. Should we book this and pay ahead of time? Can we buy the ticket when we get to the station or a few days before we depart since we will be in Zurich 2 days prior? From other TA postings I've read, Switzerland does not really provide early ticket purchase discounts.
Also, can somebody explain this SBB Notification below to me in plain English please? Will this affect our trip?
