S 12 line of the Zurich commuter network, train 19230 from Schaffhausen via Andelfingen-Winterthur-Stettbach-Zürich-Dietikon-Baden to Brugg, between Winterthur Tössmühle and Kemptthal, running with 125 km/h. Before the Corona crisis, this fastest connection between the large towns of Winterthur and Zürich, transported about 1200 passengers or more on this time of the day, after 8 AM. I assume that there are about 1/10 of them now. The trains were deliberately not shortened to allow social distancing, a completely new term in Switzerland. Re 450 # 040 "Hinwil", # 056 "Otelfingen" and # 082 "Feuerthalen" are running the train on this beautiful, but very cold morning.
