On August 2, just before 10 a.m., a catenary fault occurred in the Winterthur Tössmühle area. There was a complete disruption to services between Winterthur and Effretikon until around 1.30 p.m., as well as occasionally between Winterthur and Winterthur Töss. In the afternoon at 4.20 p.m., repair work could be observed in Winterthur Tössmühle, where 3 tracks from Winterthur join to form a double track in the direction of Kemptthal. The fire fighting and rescue train "LRZ" 9177 # 016 of Zürich is returning as train 99754 from Oberwinterthur to the home base in Zürich Altstetten, after he had pulled the defective doubledecker "DTZ" RABe 514 # 003 from Zürich Oerlikon to the Oberwinterthur maintenance center.
