When you use the advanced search on SBB.ch and in SBB Mobile you have the option of choosing trains of a given category. This way you can influence the choice of connections shown. To open the advanced search in the SBB Mobile app, tap the symbol with the three circles on the three lines on the right-hand side when searching the timetable. On SBB.ch, simply click on ‘Advanced search’ to the right of ‘Search for connection’, once you have entered your departure and destination locations. Generally, when making a general search for connections (without applying filters) the most convenient and fastest connection is selected.
