Peak hour S 12 service 19262 of the Zürich commuter network (S-Bahn Zürich) from Schaffhausen via Andelfingen-Winterthur-Stettbach-Zürich-Dietikon-Baden to Brugg (AG), between Winterthur Tössmühle and Kemptthal. 3 "DPZ" (doubledeck push-pull train) with locomotives Re 450 # 013 and two others in multiple control. Between Schaffhausen and Winterthur, there is 1 DPZ only because of the length of the platforms, from Winterthur to Brugg (AG) there are 3 DPZ. In the Corona crisis, the number of passengers is estimated to have fallen to a tenth or less compared to the previous time. The trains were deliberately not shortened to allow "social distancing", a completely new term in Switzerland. We use this english term now very often. The SBB is loosing millions of swiss francs each day of the "lock down".
