This is the IR 2114 of the line IR75 from Konstanz via Weinfelden-Winterthur-Zürich-Zug to Lucerne, between Winterthur and Winterthur Tössmühle. This day, the train is run by two doubledeck trains DPZ+ of the Zürich commuter network with locomotives Re 450 # 057 and # 114 in multiple control. Such deployments of S-Bahn rolling stock on this Interregio line occur repeatedly, especially on weekends, when events or changed timetables due to construction work create a greater need for Intercity rolling stock, which is normally used on the IR75.
