Following the cable fire near Praterstern station, Vienna’s S-Bahn network is currently facing major disruptions. This is particularly important for travelers heading to the airport, as the usual connection from Wien Mitte is also affected. Vienna Airport itself is still accessible by train – it is simply the usual route via Wien Mitte that is currently not the best option.
If you need to catch a flight, you should therefore not automatically head toward Wien Mitte. In many cases, traveling via Vienna Central Station (Wien Hauptbahnhof) is currently easier, faster, and more predictable.
## WHAT IS CURRENTLY AFFECTED?
There is currently no regular S-Bahn service between Wien-Praterstern and Quartier Belvedere, or between Wien Mitte and Geiselbergstraße. The disruption is caused by problems with the Praterstern signal box following the cable fire. Because this signal box controls signals and switches as far as the Rennweg area, the disruption extends well beyond the actual location of the fire.
For airport travelers, the main consequence is that the S7 cannot currently run all the way from Wien Mitte to the airport. Replacement transport is operating between Wien Mitte and Geiselbergstraße. From Geiselbergstraße, the S7 continues toward the airport.
The CAT is also currently not operating its regular direct service between Wien Mitte and the airport.
The good news is that the airport railway line itself is not closed. Railjet and Intercity trains between Wien Hauptbahnhof and Vienna Airport are still operating. That is exactly why the Central Station is currently the most practical alternative for many travelers.

## THE BEST GENERAL ROUTE: VIA VIENNA CENTRAL STATION
For most travelers, I would currently choose Wien Hauptbahnhof as the starting point for the final journey to the airport.
The route is simple: first travel to the Central Station by underground, tram, bus, or train. From there, take a Railjet or Intercity train directly to Vienna Airport.
The train journey itself from the Central Station to the airport takes around 15 minutes. Railjet trains usually operate several times per hour, making this option relatively easy to plan despite the additional journey to Hauptbahnhof.
From the city center, the connection is straightforward. From Stephansplatz, take the U1 directly to Hauptbahnhof. If you are at Praterstern, you can also take the U1 directly to the Central Station instead of dealing with the disrupted S-Bahn trunk line.
If you are already at Wien Mitte, take the U3 to Stephansplatz and change there to the U1 toward Hauptbahnhof.
From Wien Mitte, I would currently allow roughly 35 to 45 minutes for the entire journey to the airport, depending on how well your connection at Hauptbahnhof works out.
## WHAT IF YOU ALREADY HAVE A CAT TICKET?
There is an important point for travelers who have already purchased a CAT ticket. According to the available information, CAT tickets are being accepted on long-distance trains between Wien Hauptbahnhof and the airport during the disruption.
However, it is not entirely clear whether this also covers the journey within Vienna from Wien Mitte to Hauptbahnhof.
To be on the safe side, I would have a valid Wiener Linien ticket for this part of the journey. This avoids unnecessary stress during a ticket inspection, especially when you are already under time pressure to reach the airport.
## REPLACEMENT BUS AND S7: POSSIBLE, BUT ALLOW MORE TIME
A second option is to use the replacement service from Wien Mitte to Geiselbergstraße. From there, you can change to the S7, which continues to operate toward the airport.
This route works in principle, but it comes with several disadvantages if you are traveling with luggage. There is an additional transfer, the bus travels through normal city traffic, and the journey time is therefore less predictable. You also need to make the connection with the S7.
For a journey starting at Wien Mitte, I would therefore allow at least 60 to 75 minutes to reach the airport.
If you have a time-sensitive flight, I would consider this the second choice. Hauptbahnhof plus Railjet is usually easier to manage.
## GO DIRECTLY TO THE S7 AT GEISELBERGSTRASSE
The situation is different if you are already in southeastern Vienna. Travelers from parts of the 10th or 11th districts do not necessarily need to travel back to Hauptbahnhof first.
One option, for example, is to take the U3 toward Enkplatz or Simmering and then use a local connection to reach Geiselbergstraße station. From Geiselbergstraße, the S7 continues to Vienna Airport.
This can be a useful shortcut from Simmering, eastern Favoriten, or nearby areas.
However, I would definitely check the exact S7 departure before setting off. If you narrowly miss the train, any time saved by taking this route can quickly disappear.

## AIRPORT BUS AS A DIRECT ALTERNATIVE
If you prefer to avoid the railway disruption altogether, the Vienna Airport Bus is another option.
The connection from the Morzinplatz/Schwedenplatz area to the airport is particularly useful for travelers staying in the 1st district, 2nd district, and parts of the 20th district, as it offers a direct alternative without an additional train transfer.
Other airport bus connections operate from locations including Hauptbahnhof and Westbahnhof.
The advantage is obvious: the signal box disruption does not affect the bus.
The disadvantage is road traffic. Particularly during peak hours, actual travel times can differ from the scheduled journey time. If you have a flight to catch, you should therefore leave enough extra time even when taking the bus.
## WHEN DOES A TAXI OR RIDE SERVICE MAKE SENSE?
During a disruption like this, a taxi or ride service can make more sense than usual – especially for families.
If you are traveling with two adults, children, several suitcases, and perhaps a stroller, an additional transfer is a very different experience from traveling with just a small backpack.
A direct car journey can also be useful for a very early or late flight, a tight schedule, or when your starting point does not have a convenient connection to Hauptbahnhof.
The railway disruption does not directly affect the A4 motorway. However, it makes sense to expect potentially heavier traffic if more travelers switch to buses, taxis, and ride services.
## FROM THE AIRPORT BACK TO VIENNA
The same basic rule applies in the opposite direction: do not rely on the usual connection via Wien Mitte operating normally.
For destinations in the city center, western Vienna, or southern Vienna, the Railjet to Hauptbahnhof is usually the simplest solution. From there, you can continue, for example, on the U1 toward the city center.
If you are heading directly to the Schwedenplatz area, the Airport Bus to Morzinplatz may also be worth considering.
For destinations in the 11th district, the S7 to Geiselbergstraße can be useful, followed by a local connection.
If you are heading to Praterstern or farther north, it is better to take the Railjet to Hauptbahnhof and then continue on the U1. The disrupted S-Bahn trunk line should not currently be planned as a cross-city route.
## ALLOW EXTRA TIME AND CHECK YOUR CONNECTION AGAIN
For most airport travelers, Hauptbahnhof plus Railjet is currently the best overall solution. The Airport Bus from Schwedenplatz is a good direct alternative for parts of the city center, while the S7 from Geiselbergstraße remains particularly useful for southeastern Vienna.
I would mainly use the replacement service between Wien Mitte and Geiselbergstraße if you are already in the area and have enough time.
For a departing flight, I would allow around 20 to 30 minutes of additional buffer compared with a normal Railjet journey. If you are using the replacement service to reach the S7, I would allow closer to 45 minutes of extra time.
As it is still unclear how long the disruption will last, check your specific connection again in the latest timetable information immediately before departure. When traveling to the airport, an extra half hour is usually much more comfortable than narrowly missing your flight.
