The D route is an important one as it provides a service round a significant part of the central ring and also serves a lot of track exclusive to the route.
It is worked from the depots at Favoriten and Währinger Gürtel using B (and more recently B1) class ULF cars and E2 cars hauling c5 trailers. An odd exception can be seen in the collection.
This route was extended from 9th December 2012 as part of the redevelopment of the former Südbahnhof area which led to the route serving the new Hauptbahnhof and terminating at the new terminus at Alfred-Adler-Straße. In time it is due to be extended further as the area is redeveloped.
