Construction Final Sprint for Vienna Tram Lines and U4

The project manager from Wiener Linien, Stefan Geiger, explains that the high traffic density with thousands of cars and trams in a short period made renovation essential, as reported by ORF.

Special Strain on the Tracks at the Ring

The strain on the tracks is particularly high due to the frequently used lines. Geiger explains: “We have a load of four lines that run at a very dense frequency. This is good for our passengers, but it also means increased strain on our tracks and switches. These represent our weak points.”

In addition to the work at the Parliament, the final work on Stadiongasse will continue until the end of the month. Elsewhere, the tram construction sites are on schedule: Tram lines 6 and 18 are expected to resume service from August 23, while lines 9, 43, 71, and D will be operational from September 1.

Renovation of the U4 Subway Line During Summer Holidays

The work on the U4 is also in the renovation phase. In recent years, it has been common for the subway to be renovated on various sections during the summer. Currently, the service between Friedensbrücke and Schottenring is partially interrupted. The measures focus on the tunnel structure, whose supports have reached the end of their lifespan, as Eunike de Wilde from Wiener Linien explains to Radio Wien.

For the stability of the U4, new double beams are being constructed between Schottenring and Friedensbrücke this summer, while 15 additional beams are being renovated. These works contribute to ensuring that no further interventions will be necessary in the coming decades. The final concreting works are underway and are expected to be completed by the end of August. From the start of the school year on September 1st, the U4 will run continuously again.

Other Public Transport Construction Sites in Floridsdorf

Additionally, construction work is currently taking place on the tram tracks in Floridsdorf. These works are mainly carried out at night, testing the patience of passengers. Lines 25 and 26 are running between Franz-Jonas-Platz and Hoßplatz at a maximum speed of 15 km/h due to outdated tracks. The track renovation is taking place during ongoing operations, parallel to ÖBB works on the S-Bahn line in Floridsdorf, which is completely closed until September.

Future Changes in the Line Network

For next year, the renovation of another section on Donaufelderstraße is planned. Here, the tracks are also to be renewed. Additionally, from autumn, the new tram line 27 will be put into operation on this route to relieve the existing lines and shorten intervals. However, the new line 27 is also not initially designed for high speeds on the affected section.
