The role of buses in Swiss public transport
Buses are being used to reach towns without a train station, and for urban transport within larger cities. Travelers rarely get to choose their mode of transport in Switzerland. If you want to travel from A to B, you can fill this out in the timetable, and it will show you whether to travel by train, bus, cable car or anything else. If there is a train service connecting two towns, there usually isn't a bus service too.
