Badner Bahn

Starting from the Vienna State Opera, the service uses the tracks of Vienna's tram network as far as the Schedifkaplatz tram stop in the Meidling district, including parts of a tram tunnel. From Schedifkaplatz to Leesdorf in Baden and between Leesdorf and Josefsplatz, the train service has its own infrastructure, 25 kilometres (16 mi) of double-track light rail and 2 kilometres (1.2 mi) of tram line, respectively. These tracks are owned and maintained by Wiener Lokalbahnen.

Since 14 December 2014, there is a new train station at the state clinical center (German: Landesklinikum) in Baden. Despite its addition to the route, the length of a journey could be kept at 62 minutes.

From April until November 2024, trains will be diverted from their normal northern terminus due to construction. During this time, trains end at Quartier Belvedere station, near Wien Hauptbahnhof.

Original 26 class 100 high-floor units built between 1979 and 1993 by Simmering-Graz-Pauker served the line. In order to provide headways of 7.5 minutes 14 low-floor class 400 units were ordered from Bombardier, they were produced from 2000 to 2010 and put in operation as double-unit trains with a class 100 units to provide accessibility. In December 2018 Wiener Lokalbahnen presented the new class 500 Flexity trams designed by Bombardier Transportation (now part of Alstom), 18 trains were ordered with an option for 16 more, 12 of those were taken in 2023. The new trams will replace all remaining class 100 units of which only 10 are still in service.
