History

The S23 was introduced in the timetable revision of December 2015 as a peak-hour service between Zürich HB and Winterthur. The S23 supplemented the S11, then a peak-hour service between and Winterthur, and the S12, which operated on a hourly schedule and was "notorious" for overcrowding. Some S23 services continued to Romanshorn. At the time of its introduction the S23 was the only service on the Zürich S-Bahn whose carriages were not air-conditioned, leading to complaints from passengers during the summer months.
