The Sihltal line is electrified using the standard Swiss mainline system of overhead lines at 15kV 16.7Hz AC, whilst the Uetliberg line is electrified using overhead lines at 1200 V DC. In order to avoid conflict on the common section, the Uetliberg line uses an overhead line offset from the centre of the track, and its cars are equipped with offset mounted pantographs to collect from this.
