Do the SwissTrolley 1 have special journeys where they can be found more often?

Hi Lothar, the Swisstrolley 1s are usually only in service during peak hours on weekdays, which are between 6-9 AM and 4-7 PM. Occasionnally, there might be a ST1 which stays in service during the whole day or after 7 PM. It is worth noting that they will never operate on week-ends as well as during school holidays (except 703, which is a driver-training vehicle) ;)

Thank you
