Major project in Vienna: S-Bahn between Floridsdorf and Praterstern closed!

From June 28, 2025, things will be busy in Vienna, as ÖBB is starting a comprehensive modernization project. From 2 a.m. until September 1st, the S-Bahn route between Floridsdorf and Praterstern will be completely closed. This area is of great importance not only for commuters, but also for leisure traffic, which means that the coming weeks will have a high impact on mobility in the north of the city. After all, the route connects Vienna Floridsdorf with the city's infrastructure and plays a central role for many who travel to the capital every day.

To minimize the impact of the closure, two replacement bus routes will be set up. Theyellow lineoffers a direct bus between Praterstern and Floridsdorf without intermediate stops and runs Monday to Friday from 5:30 a.m. and on weekends from 6 a.m. to 8 p.m. Theblue lineHowever, replacement rail service will serve the Handelskai and Traisengasse stops. Both lines are offered in specially branded buses with clear lines, making orientation easier for passengers.

Replacement offers and support for passengers

Passengers can look forward to colored boards for orientation that will be installed at the relevant stops. In addition, the real-time data from the buses can be accessed in the ÖBB apps “Scotty” and “WienMobil” so that no one has to wait unnecessarily. Interestingly, ÖBB tickets are also valid on the Wiener Linien on certain routes, making it even easier to use public transport during construction work. To ensure a smooth transition, trained employees, also known as “customer guides,” are available to help find the right connection.

But it's not just the north of Vienna that's undergoing modernization. Wiener Linien also has big plans for the summer of 2025. In addition to the S-Bahn, the U4 between Schottenring and Friedensbrücke will also be revamped from June 28th to September 1st. The U4 tunnel infrastructure is over 120 years old and urgently needs to be renewed. During the work, the U4 between Heiligenstadt and Friedensbrücke as well as Hütteldorf and Schottenring will continue to operate. There are transfer options via the tram lines E4 and D, which go to Schottenring.

A look into the future

The modernization should not only improve the current situation, but also bring long-term benefits. The “S-Bahn Vienna Upgrade” program runs until the end of 2027 and aims to optimize local and regional public transport between Vienna and Lower Austria. The aim is to make the main route fit for the future and to bring more commuters to the federal capital quickly and comfortably. The route between Vienna Meidling and Floridsdorf has been the backbone of public rail transport for more than 60 years and these investments are a clear sign that Vienna will remain a do-it-yourself for commuters in the future.

Further information about current construction sites, diversions and timetables can be found on the ÖBB and Wiener Linien websites. If you would like to stay up to date, you can also call 05-1717.

The coming weeks will not only bring challenges, but also the opportunity to take Vienna's transport infrastructure to a new level. Let’s be surprised at what the future has in store for us!
