Public chaos in Vienna: Summer construction work ensure massive timetable changes!

In the Vienna area, passengers can expect in the summer months to result in significant modules for the ÖBB and the Viennese lines due to extensive construction work. From June 28th to September 1, 2025, even the trains on the S-Bahn "Vienna Main route" between Praterstern and Floridsdorf are not in use. Instead of the usual rail connections, there will be a rail replacement traffic with two bus lines. The Blue Line (SV900) holds Vienna Praterstern, Vienna Traisengasse, Vienna Handelskai and Vienna Floridsdorf, while the yellow line (SV905) offers a direct bus from Vienna Praterstern to Vienna Floridsdorf, daily from 5:30 a.m. to 8:00 p.m. On top of that, it was pointed out that the departure times of the buses are available via the Scotty Mobil-app.

The construction site work affects not only the S-Bahn, but also the U4 route, which is renewed during the summer vacation from June 28th to August 31st. The U4 then only drives from Heiligenstadt to Friedensbrücke and from Schottenring to Hütteldorf. The E4 tram line is offered as a replacement for the connection between Friedensbrücke and Schottenring, and line D is diverted from the stock exchange via Schottenring and Schwedenplatz. This means that the ring lines also experience changes and that the number of passengers could increase on some routes. In addition, the U6 and tram lines 2, 30, 31 and 44 drive into a denser interval.

modernizations for the future

The Viennese lines have set themselves clear goals and continue their modernization offensive to make the subway and tram network future-proof. The aim of this extensive work is a comprehensive modernization and digitization of routes, buildings and the rail infrastructure in the ÖBB network in and around Vienna. This should lead to modern, longer trains with more seats and enable denser clocking in rush hour. The work on tracks, soft and subway tunnels is planned at short notice in order to keep the effects on passengers as low as possible. The city is growing, and thus also the need for powerful public transport.

It is particularly noticeable that the "eastern region" of Austria, which comprises Vienna, Lower Austria and Burgenland, records the highest population growth in the country and is currently located around four million people. Against this background, the measures are essential to increase mobility for everyone and to be up to the challenges of the future.

passengers are advised to inform themselves in good time about the current changes, to plan time reserves and to acquire the tickets for rail replacement traffic online or at machines in advance. In addition, passengers should note that bicycles are not allowed in the rail replacement buses.

For more information about the construction sites and changes, the companies ask for regular visits to their websites, such as oe24.at reports, ÖBB.AT and Wienerlinien.at to always remain up to date.
