The calculations behind it are highly complex. The following rules influence the search results:
Priority 1: the fastest connection.
Priority 2: the most convenient connection (fewest changes).
Priority 3: the connection with the best train categories (e.g. an IC has priority over an S-Bahn).
The search results generated by this base calculation can also be influenced by:
personalised searches, such as “carriage of bicycles”, “via field”, “barrier-free travel” etc., which can be set in the advanced search.
popular alternative routes: for example, for the Bern – Brig route, both possible routes (1x via Lötschberg tunnel and 1x via the mountain route) are shown in the timetable.
All timetable queries take real time data into account. That means that alternative routes can also be offered.
