The timetable is updated promptly and in advance with planned changes to travel times due to engineering works. If you receive a message that says the timetable has been updated due to engineering works, you can assume that the relevant changes are visible in the timetable and the connections affected have been updated. Aside from engineering works, disruptions can also lead to unplanned changes at short notice. We therefore recommend that you always check your connection before departure in the online timetable or the SBB Mobile app.
