This is the last day in Switzerland with the public transport in "full swing". In connection with the corona crisis and the partial shutdown of public life, the timetable will be gradually thinned out from Thursday 19th March 2020 in several steps. Instead of every half an hour, express trains will only run every hour, in regional traffic where it is currently a quarter hourly service will be reduced to half an hourly service, and traffic to neighbouring countries will be completely discontinued. Tourist lines and offers were already cancelled a few days ago. Bus companies throughout Switzerland will also reduce the timetable accordingly. This is the first time that the timetable will not be expanded but reduced. The S 12 service 19234 from Schaffhausen via Winterthur-Zürich to Brugg (AG) is run by the "DPZ" (double deck push-pull train) with Re 450 # 049 and # 019 in multiple control.
