context_page_description: The Uetliberg railway line is a passenger railway line which runs from the central station in the Swiss city of Zürich through the city's western outskirts to the summit of the Uetliberg. The route serves as line S10 of the Zürich S-Bahn, with the Zürcher Verkehrsverbund's standards zonal fares applying.
  The line was opened in 1875 and electrified in 1923. In 1990 it was extended to its current terminus at Zürich Hauptbahnhof. Today it is owned by the Sihltal Zürich Uetliberg Bahn, a company that also owns the Sihltal line, and operates other transport services.
  The line has a maximum gradient of 7.9% and is the steepest standard gauge adhesion railway in Europe. It carries both leisure and local commuter traffic.
context_section_description: The Uetliberg line was built by the Uetlibergbahn-Gesellschaft, which opened its line from Selnau station in Zürich to the summit of the Uetliberg mountain in 1875. In 1892 the Sihltal line was opened by another company, running from the Uetliberg line's Selnau station to Sihlwald.
  In 1920 the Uetlibergbahn-Gesellschaft became bankrupt and was liquidated. Two years later the line was taken over by the Bahngesellschaft Zürich–Uetliberg (BZUe), and one year after that it  was electrified. The original electric rolling stock had many of the attributes of contemporary tramcars, and were designed to be regaugeable to metre gauge as there was a (never realised) plan to integrate the line with the Zürich tram network. 
  In 1932 the management of the Sihltal line took over the management of the Uetliberg line, but the two companies remained in existence until 1973, when they were merged to form the Sihltal Zürich Uetliberg Bahn. 
  In 1990, the two lines were extended from their previous joint terminus at Selnau to a terminus at Zürich HB. This extension involved the construction of a new rail tunnel from Selnau to Zurich HB, and a new underground intermediate station adjacent to the former terminus. The underground platform and tracks used at Zurich HB were already in existence, having been built prior to 1973 for a U-Bahn scheme that was ultimately rejected by voters. Once the new extension had been opened, the former terminus at Selnau was redeveloped and little evidence of it is now visible.
  Until 2008, a train of the line's original 1923 rolling stock was kept as a museum train by the SZU. However an increase in train frequencies in that year meant that the possibilities of running the stock was much reduced, and depot capacity was at a premium. The train, made up of motor car 2 and trailer C41, has since been loaned to the Swiss Transport Museum in Lucerne.
