A Summary of Major Maintenance and 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.

Also worth knowing is that many major construction work projects, which require timetable alterations, aren't confirmed until around two months ahead.

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.

1: Innsbruck ↔ Feldkirch

Due to construction work, no long-distance trains will run between Ötztal (west of Innsbruck) and Bludenz (east of Feldkirch) from October 6, 2025 , to November 3, 2025.
This route is used by all long-distance trains which typically travel between Innsbruck and both Bregenz and Zurich.
A rail replacement bus service will be provided.
Night trains will be rerouted.
Due to the construction work, there may be some restrictions on seat reservations.

2: Salzburg ↔ Kufstein

Due to construction work by Deutsche Bahn, some long-distance trains will not run between Salzburg Central Station and Kufstein Station from November 14, 2025 (9:00 p.m.) to November 19, 2025 (5:00 a.m.).
Rail replacement bus services will be provided. Some long-distance trains will have their schedules changed.
Night trains will be rerouted.

The work is being carried out by DB because between Salzburg and Kufstein, the trains on the Wien - Linz - Salzburg ↔ Kufstein - Worgl Innsbruck - Feldkirch - Bregenz / Zurich route, travel on a route through southern Germany.

(1) Until January 26th approximately one third / 33% of the Intercités trains on the Paris - Brive - Limoges - Toulouse route have been temporarily taken off the timetable due to track reconstruction work.

3 Berlin ↔ Erfurt
From September 24 (midnight) to December 13, 2025 (midnight) construction work will be taking place at multiple locations between these two locations.
As a consequence between these dates:

• Due to the diversion, trains between Erfurt / Leipzig and Berlin won't be calling in Südkreuz or Lutherstadt Wittenberg
• All ICE trains which typically take the Frankfurt - Erfurt - Berlin route will be cancelled, leaving Frankfurt - Kassel - Berlin as the only service between Frankfurt (Main) and Berlin
