History

The history of the SZU dates back to two separate companies, which built the two railways that now make up the SZU. The first of these companies was the Uetlibergbahn-Gesellschaft, which opened its line from Bahnhof Selnau in Zurich to the summit of the Uetliberg

The Üetliberg is a mountain in the Swiss plateau, part of the Albis chain, rising to 873 m . The Uetliberg offers a panoramic view of the entire city of Zurich and the Lake of Zurich. There is also a hotel in the name of "Uto Kulm" on this small mountain...

In 1920, the Uetlibergbahn-Gesellschaft became bankrupt and was liquidated. Two years later the Uetlibergbahn was taken over by the Bahngesellschaft Zürich–Uetliberg (BZUe). In 1923 the Uetlibergbahn was electrified using the direct current

In 1932 the SITB took over the management of the BZUe, but the two companies remained in existence until 1973, when they were merged to form the SZU. In the meantime, in 1954, the SITB had taken over the management of the Luftseilbahn Adliswil-Felsenegg

In 1990, the two lines were extended from their previous joint terminus at Bahnhof Selnau to an underground terminus at Zürich Hauptbahnhof. A new underground intermediate station was provided adjacent to the former terminus, which was then redeveloped.

In 1995, the company took over responsibility for bus services in parts of the district of Horgen

Also operated is a connecting line from Giesshübel to the Swiss Federal Railways at Zürich Wiedikon, although this is normally only used for freight traffic. In all, the SZU network measures 30.06 km (18.7 mi): 19.7 km (12.2 mi) km as part of the Sihltalbahn (including the Wiedikon to Giesshübel line) and 10.36 km (6.4 mi) of the Uetlibergbahn.
