D, they will gradually replace the last high-floor vehicles in the existing fleet. Depots Throughout its history, the Vienna tramway network has had a variety of Remisen ("carriage houses"), which were officially described as depots or stations. Due to the abandonment of numerous lines, some of these facilities have now been closed for trams (e.g., 2., Vorgartenstraße, 3., Erdberg, 12., Assmayergasse, 14., Breitensee, 15., Linke Wienzeile, 18., Währing, 22., Kagran). A few of them have nevertheless remained in use as operating garages for buses. In 2006, the now former Breitensee depot became the most recently abandoned facility, with its tram fleet being taken over by the Rudolfsheim station. In recent years, as part of conservation measures, some depots have been gradually closed down as a separate unit, demoted to the status of so-called Abstellanlagen ("parking facilities"), and placed under a different depot. Currently, there are four operating depots in the Vienna tramway network and six parking facilities, as well as the Erdberg station, where the Vienna Tram Museum is housed. Repair work is now performed mostly in the remaining depots, where all vehicles are now officially stationed. The depots are split into the following sectors; North - Floridsdorf, Brigittenau and Kagran, Central - Hernals and Gurtel, South - Favoriten and Simmering, West - Rudolfsheim, Ottakring and Speising. Certain Lines or vehicles are assigned to each depot or parking facility: Heavier maintenance, along with periodic servicing, is performed in the Main Workshops of the Wiener Linien.
