From spring, the Tscherttegasse station will be modernised and accessibility significantly improved. During the work, one direction of travel will pass through the U6 station at a time.  

In summer 2024, Wiener Linien renovated the tunnel girders of the U4 between Schwedenplatz and Schottenring. In 2025, it will be the turn of the section between Schottenring and Friedensbrücke. During the work, the U4 will not be able to run in this section.

We are continuing with the reconstruction of the underground Alserbach bridge: from January to the end of May, we are renewing the supporting structure under track 2. As last year, the U4 can run continuously between Hütteldorf and Heiligenstadt despite the construction work. 

Restriction from 13 January up to and including 25 February 2025: Track 2 closed

At Friedensbrücke station, the U4 will run on track 1 in both directions (alternating track operation). Only every second train runs beyond Schwedenplatz to Heiligenstadt. This results in a slightly longer interval in this section. 

During the semester break, we replaced the points on the U6 between Spittelau and Jägerstraße.

We will be replacing around 1,750 metres of track on Hütteldorfer Straße over the course of the year to eliminate slow sections. We are also improving comfort at the Johnstraße and Breitensee stops.

We are modernising the tracks in Floridsdorf from February to June. We are replacing 1,780 metres of track in the Franz-Jonas-Platz and Schloßhofer Straße areas. Due to ÖBB's work on the main S-Bahn line, Wiener Linien's work will largely have to take place when the railway is not in operation. 

Restriction from 4 February up to and including 17 June 2025:

Earlier closing time for lines 25, 26 and 31 (approx. at 00:00). The night buses N20 and N31 start earlier.

Line 18 will have 2,430 meters of new tracks on Landstraßer Hauptstraße and Schlachthausgasse. Due to the extensive work, there will be diversions and line closures. 

Jörgerstraße will receive almost 1,000 meters of new tracks to ensure smooth operation of line 43. From Elterleinplatz, the 43 will be diverted towards Gersthof and the 9 will be shortened to Rosensteingasse. The intervals of lines 2 and 44 will be shortened.

In the city center, parts of the heavily used tracks on the ring also have to be replaced. New tracks and switches are being installed on the Kärntner Ring, Universitätsring and Schubertring. Some of the ring lines have to be diverted. The U1, U2, U3 and U4 subway lines are available as alternatives.
