Construction sites and service restrictions

During the summer holidays, Wiener Linien is extensively renovating the tunnel ceiling of the U4 between Friedensbrücke and Schottenring. During the work, the U4 cannot run in this area.

Restriction from 28 June to 31 August 2025 inclusive: U4 line divided, no service between Friedensbrücke and Schottenring

The U4 runs between Heiligenstadt and Friedensbrücke and between Schottenring and Hütteldorf. 

Alternatives:

• Tram line E4: The replacement tram runs between Schottenring and Heiligenstadt and thus parallel to the U4.
• Line D: Together with the E4, Line D provides two replacement tram lines.

From April 2025 to summer 2026, Wiener Linien will be modernising the 30-year-old Tscherttegasse U6 station, which was previously only partially accessible. The station will be extensively extended and will have an additional lift, making it even more accessible. During the work, the station will run in one direction at a time.  

Restriction from 12 May to December 2025: Trains in the direction of Floridsdorf will not stop at Tscherttegasse station

Track 1 is out of service. Trains travelling in the direction of Floridsdorf will not stop at Tscherttegasse station. 

Alternative:

• To reach the Tscherttegasse U6 station in the direction of Floridsdorf, travel to Meidling station and change there to a train travelling in the opposite direction. You should allow an extra five to ten minutes for this.
• If you want to travel from the Tscherttegasse U6 station in the direction of Floridsdorf, take a train in the opposite direction, travel one stop to Am Schöpfwerk and change there to a train travelling in the direction of Floridsdorf.

At Kagran station, we are modernizing the foundation and surface of the platform in the direction of Oberlaa. Thanks to the good weather conditions and the efficient organization of the construction phases, Wiener Linien is able to complete the construction work three weeks earlier than planned. Kagran station will therefore be fully operational again from May 30.

Restriction from February 10 up to and including May 29, 2025: no stop in Kagran in the direction of Oberlaa

The U1 only stops in Kagran in the direction of Leopoldau.

Alternative:

Take the U1 in the direction of Oberlaa to Alte Donau station, get on a train in the opposite direction and travel back to Kagran. Please allow an extra ten minutes for this.

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 Easter holidays Wiener Linien will be installing new points for the U1 in the Keplerplatz area.

Restriction from 12 to 21 April 2025 inclusive: no service between Südtiroler Platz/Hauptbahnhof (main station) and Reumannplatz

During this work, the U1 will not be able to run between Südtiroler Platz/Hauptbahnhof (main station) and Reumannplatz. The U1 is divided during this period: It will run between Leopoldau and Südtiroler Platz/Hauptbahnhof (main station) and between Oberlaa and Reumannplatz.

Alternatives: Lines E1 and 6

• As a replacement, tram line E1 runs at 5-minute intervals between Reumannplatz and Quartier Belvedere during the day.
• Line 6 will also take passengers from the 10th and 11th districts to the Margaretengürtel U4 station at shorter 4-minute intervals during the Easter holidays.

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

Line 18 will receive a total of 2.4 kilometres of new tracks on Landstraßer Hauptstraße and Schlachthausgasse. The extensive work requires diversions and line closures.

Restrictions from March to early July and from late August to September 2025: Line 18 shortened and diverted

Due to the construction work, line 18 will only run between Burggasse, Stadthalle and Fasangasse on its regular route from 18 March to early July and from late August to September; from the Fasangasse stop, it will be diverted via the route of line O and via the Rennweg and Landstraße U (Wien Mitte station) S-Bahn stations to the Matthäusgasse terminus. This will allow passengers to transfer to lines U3, 71, 74A, 77A and S7. In addition to the existing public transport services, the replacement bus 18E can be used between the Fasangasse and Heinrich-Drimmel-Platz stops.

Track construction work is expected to take place in the Schlachthausgasse U area between Markhofgasse and Schnirchgasse from June onwards.

From the beginning of July to the end of August: Line 18 suspended

From the beginning of July to the end of August, line 18 will be completely suspended due to construction work on Margaretengürtel. Further information here.

From mid-June to September, we will be renewing the tracks on line 43 in Jörgerstraße. Line 43 will therefore be diverted.

Restriction from 16 June up to and including 31 August 2025: Line 43 diverted

The 43 runs on its usual route between Neuwaldegg and Elterleinplatz. From Elterleinplatz, line 43 will be diverted via the route of line 9 to Gersthof. This means that passengers can change to line 42 at Kreuzgasse and get to the city centre. During the construction work, line 9 will only run between Westbahnhof and Rosensteingasse (short route to Rosensteingasse).

Alternatives:

• Line 42: Due to the diversion of line 43, lines 42 and 43 are connected at the Vinzenzgasse stop. This means that passengers can reach the city centre or the U6 or Neuwaldegg with just one change.
• Lines 2 and 44: Lines 2 and 44 run on their usual route with more frequent intervals and take passengers to the city centre and back again.

Parts of the busy tracks on the Ringstraße need to be replaced. We are therefore installing new tracks and points on the Kärntner Ring, Universitätsring and Schubertring.

We are renewing the tracks on the Margaretengürtel in July and August. Lines 6 & 18 will therefore not be able to run between Burggasse, Stadthalle and Eichenstraße. The replacement bus 6E will be travelling instead.

Restrictions from 7 July up to and including 22 August 2025: Line 6 diverted, line 18 discontinued

• Line 6 diverted: Line 6 cannot run between Burggasse, Stadthalle and Eichenstraße. It is diverted from Eichenstraße to Meidling station. The replacement bus 6E is travelling as a substitute.
• Line 18 cancelled: Line 18 is also cancelled between Burggasse, Stadthalle and Eichenstraße. As track construction work is taking place on line 18 in St. Marx at the same time, line 18 is cancelled.
• Line 62 diverted: Line 62 will run to Matthäusgasse as a replacement for line 18.

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. 

Restriction from 7 April to June 2025 (phase 2): closure between Urban Loritz Platz and Baumgarten

Line 49 cannot run, it is cancelled. Line 12A is shortened until the end of April. Line 52 is extended in both directions and takes over the 49 sections between Baumgarten and Hütteldorfer Straße as well as between Urban Loritz Platz and Ring, Volkstheater.

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.

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