Modernisations and service changes

In 2024, Wiener Linien is modernising its network at 100 locations. The majority of the construction sites have no impact on public transport operations. However, such extensive modernisation is not possible without service changes or restrictions. Find out here when and where you can expect service changes.

Modernisations on the underground network

Wiener Linien is building a new bridge over the Alserbach, which flows underground. The existing structure is over 125 years old and needs to be completely renovated.

Since February, Wiener Linien has been constructing the 120 metre long and 14.5 metre wide bridge support structure at Aspern Nord, on which the new line 27 will run over the U2 underground line and the S-Bahn in future. We will then build the tracks in the Hausfeldstraße (from mid-February 2024), Pirquetgasse/Berresgasse (from March 2024) and Hirschstettner Hauptallee (from autumn 2024) areas. Completion is planned for autumn 2025.

In August, Wiener Linien is installing switches for the new tram line 12 on line O. The section of line O between Praterstern and Bruno Marek Allee is therefore closed.

Duration of the restriction:

5 August up to and including 1 September 2024

Bus route 11B will only run between Friedrich-Engels-Platz and the Vorgartenstraße U1 underground station.

100 construction sites, only a quarter have an impact on operations

graphic and timetable of modernisations and service changes 2024

Wiener Linien will be using hammers, drills and excavator shovels at a total of 100 locations in 2024. Our passengers will notice little or nothing of most of the modernisation work. This is because, where possible, we work during non-operating times or plan the work in such a way that it does not affect ongoing operations. Only a quarter of the measures have a noticeable impact on public transport operations.

Some of the extensive modernisation measures, such as large-scale track replacements, substructure renewals or tunnel girder renovations, are only possible when operations are interrupted. For reasons of efficiency and economy, it is necessary to divide, reroute or short-circuit lines. The complete cancellation of a line is the absolute exception.

Construction planning: close coordination with the City of Vienna

Wiener Linien works closely with the departments of the City of Vienna in construction planning. This means that necessary earthworks such as sewer renovation or district heating connections can be carried out at the same time as track construction work. Where possible, Wiener Linien's construction work is also combined with a redesign of the surface or vice versa. Examples of this are the modernisation work on the tunnel ceiling in Praterstraße and the renewal of the tracks in Wiedner Hauptstraße. This significantly increases the added value of the modernisation measures.
