For passengers, this means that they may not be able to reach their destination without hindrance. In 2025, for example, there are again some closures in the subway network on the agenda. The U4 will be split again in the summer, this time in the section between Schottenring and Friedensbrücke.

However, the restrictions on the green line start earlier. From January 13th to the end of February, only every second train can travel to Heiligenstadt due to work on a bridge structure.

Viennese U4 Not Continuously Operating in Summer

In the summer of 2024, the Viennese Lines renovated the tunnel supports of the U4 between Schwedenplatz and Schottenring, which resulted in a split operation. In 2025, it is now the turn of the section between Schottenring and Friedensbrücke. While work is being carried out there, the U4 cannot pass through this area. A replacement service has been announced.

The restrictions on the U1 are less consequential. In Kagran, the platform in the direction of Oberlaa is being renewed. The trains will pass through the station on this side without stopping from March to July.

Viennese U6 Also with Short Interruptions

The U6 will receive new switches between Spittelau and Jägerstraße during the semester holidays and the autumn holidays. This also means a forced split, at least during this period. According to the Viennese Lines, the line 33 will then also run on weekends and evenings between Josefstädter Straße and Jägerstraße.

From spring, the U6 station Tscherttegasse will be modernised. During the work, one side of the stop will be passed through at a time.

Exchange of Eleven Kilometres of Tram Tracks in Vienna

Work is also being done on the tram network. In 2024, 8.6 kilometres of tram tracks and 53 switches were already replaced throughout Vienna, the transport companies emphasise. The track renewal will continue in 2025: eleven kilometres of tracks will be replaced, along with 45 new switches. This is primarily intended to reduce slow travel spots.

Not represented in the list of planned operational restrictions this year is the U2 subway line. Its years-long partial closure ended in early December. It has since been running again between Schottentor and Karlsplatz.

The comeback of the purple line certainly attracted a lot of interest, as platform doors can now be found on this section. However, the system, which is new for Vienna, did not always work flawlessly at the start, with some of the installed sliding doors refusing to operate.
