Re 421 # 393 (Re 4/4 II # 11393) in the TRANS EUROP EXPRESS paint scheme and Re 421 # 387 (Re 4/4 II # 11387) in the RHEINGOLD paint scheme of the International Rolling Stock Investment AG (IRSI) in multiple control pull the loaded excavation train 69724 from Langnau am Albis (Sihl valley, SZU) via Sihlbrugg-Zug-Affoltern am Albis-Zürich Altstetten-Bülach to Hüntwangen-Wil, between Glattfelden and Eglisau. The material comes from a tunnel built between the Sihl valley and Lake Zurich near Thalwil to divert some of the water into Lake Zurich during heavy flooding of the Sihl in order to prevent flooding in Zurich, particularly in the area of the main railway station. In Hüntwangen-Wil, the material is used to fill the pits created by gravel extraction.
