Yard scene of the home of the SZU at Giesshübel at evening.Have a look at the many overhead lines! This is the home of both, the maine line of the SZU to Sihlwald and the steep line to the mountain of Uetli.Both railway lines are constructed to standard gauge. They are unusual in that, whilst the Sihltalbahn is electrified using the standard Swiss mainline system of overhead lines at 15kV 16.7Hz AC, the Uetlibergbahn is electrified using overhead lines at 1200 V DC. In order to avoid conflict on the common section, the Uetlibergbahn uses an overhead line offset from the centre of the track, and its cars are equipped with specially designed pantographs to collect from this.
