Hello dcg53emg
The travel via Gotthard will still be possible. If not via the Gotthard base tunnel (which will be partially reopened for passenger trains from the Easter weekend), then via the Panorama line as right now.
Please consult the SBB timetable by either downloading the SBB Mobile app or by visiting sbb.ch/en.
The timetable for June is not out yet completely.
Let us know should you have more queries.
Best regards,
Roland
Kind regards,
Roland
