A Summary of major Construction Projects

The vast majority of the work to improve railway lines, which impacts on the frequency and journey times info as per the journey guides, is completed over one Sat/Sun period.
So if you can't find a usual route or a train departure online, it can be worth having a look at the links to the national construction work, which you will find below.
You may then have to translate what you'll find, but it can be worth the effort to discover what's occurring and to glean whether you'll need to take a bus for part of the journey, or whether trains are being diverted.
Alterations to the usual service are often not particularly obvious when looking up the journey on a ticket booking service.

The information included below is a guide to the the more extensive construction projects which are impacting on train services for a week or more.
Therefore these are the projects which are good to be aware of if you're planning a rail pass itinerary and want to avoid any hassle, or are wondering why a typical connection isn't available on multiple dates.

These are the upcoming rail construction projects which;

• last more than a weekend, so also impact on Monday to Friday travel
• affect long-distance express trains
• result in trains being diverted, with longer journey times (which impacts on connections)
• Or, are being substituted by buses for part of the journey.

The Tauern Railway

A key rail route in Austria, the Tauern Railway, is to be closed for more than six months, for construction work until July 27th.
The Tauern Railway is the main railway route in south-west Austria, as it links Salzburg with Villach and Klagenfurt, but until March 2nd the plan is for express buses to replace trains between Bischofshofen and Spittal-Millstätter.
Though trains will be able to travel beyond Bischofshofen to provide a direct service between Salzburg and the other key destination along the route, which is Bad Gastein.

So until June 27th there will be no trains operating between Bad Gastein and Spittal-Millstätter.
The long distance services which typically travel the length of the Tauern Railway are on these two routes.

1. Frankfurt (Main) - Stuttgart - München Hbf - Salzburg ↔ Bischofshofen - Bad Gastein - Spittal-Millstätter - Villach - Klagenfurt
2. Wien Hbf - St Polten - Linz - Salzburg ↔ Bischofshofen - Bad Gastein - Spittal-Millstätter - Villach - Klagenfurt
   A key function of these trains to/from Wien Hbf is to provide a direct link between both Wien and Linz with Bad Gastein, but during the work these trains will be turned around in Salzburg.

There will be EC trains operating a Frankfurt (Main) - Stuttgart - München Hbf - Salzburg ↔ Bischofshofen - Bad Gastein service, but until June 27th there will be no direct trains between Salzburg and the resort towns on the Worthersee between Villach and Klagenfurt.
The trains taking the Wien - Leoben ↔ Klagenfurt - Villach route are unaffected and it looks as though more of them will have their journeys extended beyond Villach to/from Spittal-Millstätter.

What will be impacted by the work on the Tauern Railway are the daytime rail journeys which link Germany, Salzburg and other destinations in western Austria with Slovenia and Croatia.
The trains on the Frankfurt (Main) - Stuttgart - München Hbf - Salzburg ↔ Bischofshofen - Bad Gastein - Spittal-Millstätter - Villach - Klagenfurt route typically connect at Villach with trains taking a Villach ↔ Lesce-Beld - Ljubljana - Zidane Most - Zagreb - Vinkovici route.

**Vienna / Wien ↔ Salzburg **

Due to construction work, long-distance trains will run with modified travel times between Vienna Hbf (U) and Salzburg Hbf from May 12, 2025 to June 5, 2025. ~
The night trains and long-distance trains will be diverted between Vienna Hbf and St. Pölten Hbf .
Some long-distance trains cannot run and connections cannot be guaranteed.
Due to the construction work, there may be some restrictions when booking seat reservations.

• trains travelling between Barcelona and Sitges
• the Euromed and Torre Orro services on the Barcelona - Camp De Tarragona - Castello - Valencia and beyond routes
