Underground modernisation in the first quarter of 2026

U3 Gasometer 🚧 Construction of new station entrances

Wiener Linien is expanding the U3 Gasometer station with two new, barrier-free entrances. Both platforms will have additional access points with stairs and lifts. 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 29 May (start of operations): 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.

Renewal of tunnel waterproofing

Wiener Linien is renewing the waterproofing of underground structures. This will ensure that no moisture can penetrate the tunnels in the coming decades. The work is being carried out at street level and has no impact on underground or tram services in the tunnel.


Wiener Linien will be working on these tunnels in 2026:
 

  • U1 tunnel in the Favoritenstraße area
  • U4 tunnel in the Vordere Zollamtsstraße area, at the level of the Zollamtssteg. At the same time, Wiener Netze will be renovating district heating shafts there until autumn.
  • U4 tunnel in the Naschmarkt/Rechte Wienzeile area
  • USTRAB (underground tram) in the Margaretengürtel/Landgutgasse area

Stay up to date

We continuously update information about our construction sites here on our website. We also keep you informed about current and planned construction sites via our social media channels and the Wiener Linien newsletter.

The Vienna public transport network needs both: network expansion and infrastructure modernisation.

An efficient public transport network needs both expansion and ongoing maintenance. Here on our website, you find information about the expansion of the public transport network and about the modernisation of our infrastructure.

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.

Some modernisation work necessitates changes to timetables. You can find the current timetables here.
