 In autumn 2008, the Salzburg Municipal Council decided to electrify the branch of bus line 20 to Sam / Lankessiedlung.The route follows that of line 20 from Lankessiedlung, via the Salzburg-Gnigl S-Bahn station, Fuggerstraße, Volksgarten, Hanuschplatz to the Landeskrankenhaus; the line leads back to Hanuschplatz and to Sam, via Edward-Baumgartner-Straße and Karajanplatz.This work was completed in mid-2009, and bus line 20 became trolleybus line 10.
