Since stations and stops differ in size, passengers need different lengths of time to get from A to B.
The timetable therefore includes different interchange times required for changing mode of transport at each stop. The standard time is 2 minutes. However, for larger stations this interchange time is increased, for example to 7 minutes for Zürich HB.
The interchange time can be amended by the individual passenger on SBB.ch. In the advanced search, this can be extended to a given time interval (10 min, 20 min or 30 min). Under “via” you can even set an personalised interchange time.
