Construction work began in April 2025 and has no impact on underground operations. From 2027, passengers will be able to conveniently reach the Gasometer station via Medwedweg and Nussbaumallee in addition to the existing exit.

U6 Tscherttegasse 🚧 February to May: Platform closed in the direction of Siebenhirten
From April 2025 to May 2026, Wiener Linien will be modernising the 30-year-old Tscherttegasse U6 station, which has only been partially accessible to date. The station will be extensively expanded and will receive an additional lift, making it even more accessible. During the works, trains will only stop at the station in one direction.
🚧 Restriction from 2 February to late May: no stops in the direction of Siebenhirten
The platform in the direction of Siebenhirten is closed due to modernisation and renovation works.
➡️ Alternative: use a train travelling in the other direction
To reach the U6 station Tscherttegasse in the direction of Siebenhirten, travel to the station Am Schöpfwerk, change there to a train travelling in the opposite direction and travel one stop to Tscherttegasse. You should allow five to ten minutes extra for this.
If you want to travel from the U6 station Tscherttegasse in the direction of Siebenhirten, take a train in the direction of Floridsdorf, travel one stop to Bahnhof Meidling and change there to a train in the direction of Siebenhirten. You should allow an extra five to ten minutes for this.

Network expansion and infrastructure modernisation
An efficient, attractive public transport network not only needs to be expanded, but also requires ongoing maintenance and upkeep. Here on our website, you will find information on both aspects:
We are increasingly focusing on large-scale renovations
We carry out most track construction work during non-operating hours (that is, at night), during holidays or even during ongoing operations. This allows us to avoid restrictions for passengers, but we can only achieve selective improvements. In contrast, large construction sites, which we implement together with other departments of the City of Vienna, are much more effective: public transport passengers enjoy noticeable improvements, and residents only have to put up with a construction site on their doorstep once. A large construction site may cause short-term restrictions, but it means that an entire section of road is made fit for the next few decades.
