 A new turning facility on the Aiglhofkreuzung from line 4 to line 2 was created in spring 2008, as well as a dedicated lane for trolleybuses in the Griesgasse in the city centre.The latter allows the stacking-and-demand retrieval of trolleybuses in the city centre for events.With the timetable change on 7 December 2007, line 4 was extended from Langwied over the city boundary to Mayrwies, replacing bus line 4A.
