2020
From March, the coronavirus pandemic has a major impact on public transport. The Swiss public transport system reduces the timetable for several weeks: the fastest timetable alteration on record. The pandemic leads to lower passenger numbers for two years. From 1 June 2020, responsibility for PostBus route 241 Schüpfheim–Sörenberg, served by PostBus operator Schnider Bus GmbH, Schüpfheim, is assumed by PostBus operator Amstein Bus AG, Willisau. Former PostBus operators Gabi and Toni Schnider continue to work for PostBus as drivers.
