Large S-Bahn closure in Vienna: Summer modernization starts!

In the summer of 2025 there are large construction sites in the federal capital of Vienna, which will affect both the S-Bahn and the subway. From June 28 to September 1, the S-Bahn between Floridsdorf and Praterstern will be completely closed due to extensive modernization work. The ÖBB is working on the future viability of the main route in order to continue to enable passengers a dense clock and safe travel in the future. These measures are part of a large -scale project to renew rail infrastructure. As the Bahnblogstelle , the work takes place during the summer vacation to keep possible impairments for the commuters.

The modernizations include the extension of platforms, the renewal of construction and structures as well as the implementation of the digital train protection system ETCS, which should ensure a denser timetable. During the blocking, tracks, soft and overhead lines are repaired. At the same time, replacement traffic with buses is set up in the characteristic ÖBB design in order to comfortably bring passengers to their destination.

replacement traffic during construction work

Passengers can look forward to two replacement bus lines. The yellow line is a direct bus that runs between Vienna Praterstern and Vienna Floridsdorf without a stopover, daily from 05:30/06: 00 to 8:00 p.m. The blue line, on the other hand, is designed as a classic rail replacement traffic and has stops in Vienna Traisengasse and Vienna Handelskai. Overall, replacement traffic is monitored around the clock, and valid ÖBB tickets are recognized by the Viennese lines on defined replacement routes. A new coloring system ensures better orientation.

But that's not all: the Viennese lines also hold up the hammer. Update the U4 over the summer months and perform track renovations in the entire city area. The section between Schottenring and Friedensbrücke is particularly affected, where the tunnel infrastructure is over 120 years old. As the Wiener Linien report, the U4 run between Heiligenstadt and Friedensbrücke and between Hütteldorf and Schottenring. Passengers have the opportunity to switch to tram line E4 and the diverted line D.

further track work in the city

In this context, track work on several tram lines is also due. The Carinthian Ring, University Ring and Schubertring will be massively renovated from July to the end of August. Lines D, 1, 2 and 71 are briefly carried out or diverted, but the subway lines U1, U2, U3 and U4 are available to passengers. The track renovation in Floridsdorf is also continued when the operation is running. The tracks on Schloßhofer Straße will be renewed from August 8th. Many traffic flows are coordinated here at the same time.

For everyone who is traveling in Vienna in summer, a lot is offered: the intervals of the other subway lines are compressed in the area of ​​the construction sites, so that the U2 and U4 can run during the summer vacation every 5 minutes. Tram lines 2, 30, 31, 38 and 44 also benefit from this measure.

With the large -scale modernization offensive, which started in 2024, Vienna shows itself on the right path into the future. The new tram lines 12 and 27 are scheduled to go into operation in autumn, and construction work to extend line 18 to the stadium will start shortly. These initiatives are not only necessary, but also an investment in the quality of life of the Viennese.
