Modernisation and service changes

In 2024, Wiener Linien will modernise its network at 100 locations. The majority of the construction sites will 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.

Current timetables

Some modernisation work requires changes to timetables. You can always find the most up-to-date timetables here:

Timetables

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.

Modernisation of the underground train network in 2024

During the summer holidays, Wiener Linien will continue the renovation of the tunnel girders at Franz Josefs Kai.

Restrictions:

The U4 will not run between Schwedenplatz and Schottenring.

From 5 August up to and including 24 November, we are renewing the platform in the direction of Leopoldau. To ensure that the U1 can still run at the usual dense intervals, trains travelling in the direction of Leopoldau will not stop at Kagran station during the day. For safety reasons, no work can be carried out on the platform during this time; the modernisation work takes place at night. For this reason, we will be setting up a single-track platform switching service in this section every day from 11pm to 5am, i.e. trains travelling in both directions will stop at the platform in the Oberlaa direction.

Restrictions:

No stop in the direction of Leopoldau during the day
Daily from 11pm single-track alternating operation: Trains in both directions stop in Kagran on the platform in the direction of Oberlaa

Alternative:

You should allow an extra 5 to 10 minutes for this. From 11pm to 5am, trains travelling in both directions stop at Kagran station on the platform in the direction of Oberlaa.

S-Bahn Vienna Upgrade: ÖBB S-Bahn between Floridsdorf and Praterstern closed in July and August

The main ÖBB S-Bahn line between Vienna Meidling and Vienna Floridsdorf was opened in 1962, over 60 years ago. Today, around 700 trains run here every day and the line has reached its capacity limit. To ensure that local and regional public transport between Vienna and Lower Austria remains punctual and reliable in the long term, ÖBB has launched the S-Bahn Vienna upgrade.

The upgrade centres on the renewal of the rail infrastructure, the construction of new stabling and turning facilities, the extension of platforms and the conversion to the digital S-Bahn. The work for the Vienna S-Bahn upgrade will be carried out between autumn 2023 and December 2027. Work that cannot be carried out while the railway is still in operation will be bundled in order to implement it as quickly and efficiently as possible.
