What Sihltal Zürich Uetliberg Bahn does

Sihltal Zürich Uetliberg Bahn SZU AG is a Swiss regional public transport operator headquartered at Wolframplatz 21, 8045 Zürich, operating within the ZVV (Zürcher Verkehrsverbund) integrated network. The company runs four core services: the Sihltalbahn S4 commuter rail line connecting Zürich HB to Sihlwald, the Uetlibergbahn S10 rail line to Uetliberg mountain, the Felseneggbahn cable car between Adliswil and Felsenegg (integrated via 2023 merger with LAF AG), and the Zimmerbergbus regional bus service covering the left shore of Lake Zürich and the Sihltal region. SZU employs approximately 280 people and serves roughly 27 million passengers annually across these modes, with the Zürich HB SZU underground station handling ~40,000 daily boardings and alightings.

The company's business model combines farebox revenue from ZVV-integrated ticketing with public transport concessions and subsidies from Canton Zürich and Swiss federal authorities. Customers include daily commuters traveling between Zürich city center and residential areas in the Sihltal and Uetliberg regions, as well as leisure travelers accessing recreation destinations including Sihlwald forest, Uetliberg mountain, and the Panoramaweg hiking trail. Distribution occurs through ZVV station counters, automated ticket machines, the ZVV mobile app, and the ZVV-Contact customer centers.

SZU is currently executing the SZU_4.0 modernization program—a CHF 800 million, ten-year investment covering new rolling stock (RBe 546 for S4, Be 570 for S10), station expansions including the Zürich HB SZU underground station renovation for BehiG accessibility compliance, double-track sections, and timetable improvements to 15'/7.5' intervals. The company is a privately held stock corporation (Aktiengesellschaft) with named shareholders, not listed on any stock exchange. Founded in 1875 with predecessor roots to 1835, SZU is led by Director Mischa Nugent and operates under Swiss federal railway safety regulations.
