Hello, In last day in Swiss, I and my husband will go to Paris and we bought supersaver ticket from Grindelwald to Basel SBB.
But, I've heard that it will be construction between Interlaken Ost - Zweilutschinen on that day and there will be a train replacement with busses.
I've know that supersaver ticket only vaild on that train and on that time.
If the bus were delayed and we were missed the next train from Interlaken Ost to Basel SBB for going to Paris, how can we go to Basel station? In that case, can we receive a new ticket?
