A Summary of Major Works on the Railway Lines

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) Due to construction work, no long distance-trains can operate between Bruck/Mur Bahnhof and Graz Hbf from 13/09/2026 (08:00pm) through 29/09/2026 (04:00am).

(2) Due to construction work, some long-distance trains between Klagenfurt Hbf and Villach Hbf will be cancelled from October 19, 2026 to November 12, 2026 (4:00 AM). We have arranged a rail replacement bus service. Due to the construction work, there may be some restrictions on seat reservations.
We apologize for any inconvenience.

(3) Due to construction work, no trains will run between St. Pölten Central Station and Mariazell Station from November 2nd to November 20th, 2026.
A rail replacement bus service will be provided.

(4) Due to construction work, no local-trains and some long-distance trains cannot operate between Klagenfurt Hbf and Villach Hbf from 23/11/2026 (08:00am) through to 30/11/2026 (04:00pm).
Rail replacement bus services will be arranged.

For much of 2026 there will be a series of closures and alterations north of Aarhus, due to the project to electrify the railway between Aarhus and Aalborg.

Though the IC and Lyn services between the two cities will still be available.

(1) From August 10 to December 12 due to work on the high speed line north of Arras. some TGV INOUI trains which travel to and from Lille will operate at reduced speeds or take a different route.
Consequently, route changes and train cancellations are to be expected.

(2) From Sunday, November 8, at 11:00 p.m. to Sunday, November 15, at 12:00 p.m. TER trains bound for the Côte d’Azur will depart from or terminate at Marseille Blancarde station (accessible via Metro Line 1) instead of at the main Marseille-St Charles station.
The TER trains will be taking the Marseille - Toulon - St Raphael - Cannes - Antibes - Nice route.

1: At Stuttgart Hbf

From June 26th to September 11th inclusive fewer long-distance trains will be able to use Stuttgart Hbf.
The core consequences will be:

• Only one ICE train per hour between Stuttgart and both Mannheim (routes to the north) and Munich (routes to the south)
• Trains to/from Austria will call at Essingen/Neckar station instead of at Stuttgart Hbf
• There will be no direct trains at all between Stuttgart and Heidelberg, a connection will be required at Vaihingen (Enz)
• Therefore the IC and ICE trains which travel via Heidelberg and typically terminate at Stuttgart, will be terminating at Heidelberg
• The IC Trains between Stuttgart and Zurich will be beginning and ending their journeys at Stuttgart-Vaihingen station.

2: in Hamburg

The line between Hamburg Hbf and Hamburg-Altona stations has been shut down for a bridge replacement

As a consequence until Sept 21st services are having to be reduced as follows

• All long-distance train stops in Hamburg Altona and Hamburg Dammtor will be cancelled; trains will be turned around at Hamburg Hbf.
• ICE trains run approximately every hour to/from Hamburg Hbf in/to North Rhine-Westphalia via Bremen
• ICE trains run approximately every hour to/from Frankfurt and southern Germany via Frankfurt.
• There are hourly ICE trains to/from Berlin from/to Hamburg Hbf.
• to/from Munich via Hanover, there are at least ICE trans every other hour, but they will be starting / finishing their journeys at Hamburg - Harburg.
• Only 2 x ICE trains per day will run to/from Kiel.

2: From / to Obertsdorf

Until October 9th, then from October 19th to 24th, then from October 31st to November 5th and from November 13th to 16th, ICE trains won't be serving Obertsdorf and instead will be turning round in Stuttgart.

3: Bonn / Wiesbaden ↔ Mainz - Frankfurt (Main)

Until December 12, 2026 (11:59 PM)

Fewer trains than usual will be able to use the Koln - Bonn - Koblenz - Bingen - Mainz route.
A maximum of one long-distance train per hour will be available.

• The IC trains on the Emden - Rheine - Münster(West) - Gelsenkirchen - Duisburg - Dusseldorf - Koln - Bonn - Koblenz route will only be operating Emden ↔ Koln.
• The ICE trains on the Wiesbaden - Mainz - Frankfurt (Main) ↔ Dresden route won't be calling in Mainz.
• The ICE trains which typically take a Koblenz - Bonn - Koln ↔ Berlin route won't be running south of Koln.

It seems that the work is being carried out on the parallel route on the east bank of the Rhine, with a diversion of freight trains etc to the west bank route through Bonn, Koblenz and Bingen - leading to the reduction of passenger train services on the west bank route.

The long -distance Regional passenger services which take the east bank are being more drastically impacted:

• The RE8 trains on the Monchengladbach - Koln - Troisdorf - Koblenz route are being replaced by buses between Troisdorf and Koblenz
• The RB10 trains on the Frankfurt (Main) - Wiesbaden - Rudesheim - Koblenz route are being replaced by buses between Wiesbaden and Koblenz.
  As a consequence locations on the east bank of the Rhine between Troisdorf and Wiesbaden including Bad Honningen, Rheinbrohl, Leutesdorf, Neuwied, Vallendar, Braubach, Osterpai, Lorch and Rudesheim will have no rail service from July 10 (9 PM) to December 12, 2026 (11:59 PM).

Until September 18, 2026 (9 p.m.)

During this time the remaining long-distance trains through Mainz will also be impacted.

• The ICE trains which typically take a Koln- Koblenz - Mainz - Frankfurt - Nurnberg route won't be calling in Mainz or Frankfurt Flughafen
• The ICE trains on the Wiesbaden - Mainz - Frankfurt (Main) - Leipzig - Dresden route will be turning around at Frankfurt Flughafen and won't be serving Mainz and Wiesbaden
• The ICE trains on the Hamburg - Kassel -Frankfurt (Main) - Mainz - Wiesbaden route will only be operating between Hamburg and Frankfurt (Main) on most of these dates.

4: Berlin

From June 14th to October 1st:

• ICE trains won't be using Berlin Ost
• The trains between Berlin and Poland will be departing from and arriving at Berlin-Gesundbrunnen instead of Berlin Hbf and won't be calling at Berlin Ost.

From October 2nd to December 12th:

• The ICE trains which take a Berlin <> Frankfurt (Main) and beyond route via Kassel, will be diverted on to an alternative route via Erfurt; These trains also won't be using Berlin Ost and Berlin-Spandau stations.
• The trains between Berlin and Poland will be departing from and arriving at Berlin-Gesundbrunnen instead of Berlin Hbf and won't be calling at Berlin Ost.

5: The IC train route through Seigen

These are the upcoming major works on the railway lines, that will be impacting on international railway routes over sustained periods of time.

Until December 12th there will be no direct service of ICE trains between Paris and Berlin.
The daily round-trip service will operate only between Paris and Frankfurt.

Customers who have already purchased a ticket to one of the stations not being served may keep it. It entitles you to take:

• any train between Berlin and Frankfurt to travel from your scheduled boarding station, then take the scheduled train in Frankfurt
• any train between Frankfurt and Berlin to reach your scheduled destination station after arriving in Frankfurt.

From February 7th 2026 until December 12th 2026, Deutsche Bahn will be enhancing the railway in south-east Germany which links Nuremberg to Passau via Regensburg.
Hence during this time these ICE routes won't be available;

• Hamburg - Hannover - Kassel - Wurzburg - Nuremberg - Regensburg - Passau ↔ Wels- Linz - Vienna
• Berlin - Halle - Erfurt - Nuremberg - Regensburg - Passau ↔ Wels - Linz - Vienna; this service will be switched to a Berlin - Halle - Leipzig - Erfurt - Nuremberg - Munich - Kufstein - Worgl - Innsbruck route.

From July 11th to December 12th the services which will be available are:

• One ICE train per day taking a Cologne - Frankfurt Airport - Frankfurt (Main) - Wurzburg - Nuremberg - Regensburg route
• One ICE train per day taking a Hamburg - Hannover - Kassel - Wurzburg - Nuremberg - Regensburg route
• 3 x EC trains per day taking a Munich - Simbach ↔ Wels - Linz - Vienna route.
• 2 x ICE trains per day taking a Munich - Regensburg - Passau ↔ Wels - Linz - Vienna route

The idea being that travellers who want to travel between Germany and the route via Wels and Linz to / from Wien, can make connections at the main station in Munich.
These ICE and EC trains on the Munich ↔ - Linz - Vienna routes will be in addition to the usual service of RJX trains which depart in every other hour

The Nightjet trains on the Amsterdam ↔ Vienna and Hamburg ↔ Vienna routes will still be available, but will be diverted.

From 08:30 on June 14th 2026, until 23:59 on October 14th 2026, trains will be unable to take the usual main cross border rfailway between Austria and Switzerland; the Sargans - Buchs ↔ Feldkirch route.
Therefore from June 14th to Oct 14th inclusive, a bus replacement service will be operating Sargans ↔ Feldkirch.

This will have the following impacts on rail services during this time:

• The number of direct Railjet (RJX) services on the Zurich - Buchs ↔ Feldkirch - Innsbruck - Salzburg - Linz - Wien / Vienna route will be reduced.
• Westbound departures from Zurich HB station will be at, 06:36 (EC) train to Innsbruck; and RJX trains to Wien will depart at 08:32, 10:32 and 14:32.
• Eastbound departures from Wien Hbf will be at 12:56 and 16:56, with a train beginning its journey in Linz at 05:30; Departures from Salzburg Hbf will be at 06:56, 12:56 and 16:56.
• An EC train will depart Innsbruck for Zurich at 17:16; and the Railjet trains to Zurich will depart from Innsbruck at 09:16, 13:16 and 15:16.
• The trains travelling between Zurich and Austria will be diverted on to a different route and will be calling at Zurich Flughafen / Airport, Winterthur, St Gallen and Bregenz, instead of at Sargans and Buchs.
• As a result of the diversion, journey times from and to Zurich will be extended by around 80 minutes.
• The daily Railjet (RJX ) train which typically takes a Zurich - Buchs ↔ Feldkirch - Innsbruck - Salzburg - Linz - Wien / Vienna - Budapest route, will be diverted to travel to and from Bregenz instead of Zurich.
• The daily Railjet (RJX ) train which typically takes a Zurich - Buchs ↔ Feldkirch - Innsbruck - Salzburg - Linz - Wien / Vienna - Bratislava route will be travelling between Feldkirch and Budapest.
• The daily 'Transalpin' service which typically takes a Zurich - Buchs ↔ Feldkirch - Innsbruck - Zell-am-See - Radstadt - Leoben - Graz route will bei travelling between Innsbruck and Graz
• Timings of the night trains between Zurich and Budapest, Graz, Wien and Zagreb will be altered.

From October 2nd to December 12th 2026:

The trains will be impacted by works on the line between Hannover and Berlin.
Instead of trains every two hours on a Amsterdam - Amersfoort - Deventer - Osnabruck - Hannover - Berlin, there will be trains every four hours between Amsterdam and Hannover, with only two of these trains in each direction per day travelling beyond Hannover from / to Berlin.

(1) On Mondays only from March 16 (8:50 a.m.) to December 7, 2026 (6:50 p.m.) buses will replace trains between Dresden Hbf and Usti nad Labem.
As a consequence on these Mondays, the service along the (Copenhagen) Hamburg - Berlin - Dresden - Decin - Praha - Brno - Budapest / Wien will be split, with trains operating Copenhagen) Hamburg - Berlin ↔ Dresden and Decin ↔ Praha - Brno - Budapest / Wien, with the stop in Bad Schandau being omitted.

(2) From September 30 to October 4 and on October 6, 2026, each day from 9:10 a.m. to 5:10 p.m due to bridge replacement work a replacement bus service will be provided between Dresden Hbf and Usti nad Labem.
In Dresden there is a connection to the trains of the IC line 17 (Rostock - Berlin - Dresden) to/from Berlin.
In Usti nad Labem there is a connection to the trains of the RJ line 27 ((Copenhagen -) Hamburg - Berlin - Dresden - Prague) to/from Prague.

Due to construction work in Italy no long-distance trains can operate between Villach Hbf and Udine from 22/08/2026 through 20/09/2026.

The Nightjet trains on the Vienna and Munich ↔ Rome and Venice routes will be diverted.

Due to construction work in Italy, the trains NJ 236, NJ 40236, NJ 237 and NJ 40466 will be diverted between Venezia Mestre and Salzburg Hbf from 21/08/2026 through 20/09/2026.
Therefore during these this time the trains cannot stop in Treviso Centrale, Conegliano, Pordenone, Udine, Tarvisio-Boscoverde and Villach Hbf.

From 10:35 p.m. on September 11 to 10:35 p.m. on October 9 the TGV France/Italy (SVI) trains are canceled due to construction work connected to the construction of the future Lyon - Turin tunnel.
Presumably the Frecce trains on this route will be similarly affected.

Due to construction work by Slovenian Railways (SZ), no long-distance trains will run between Villach Hbf and Lesce-Bled
from September 26, 2026 to November 11, 2026.
A rail replacement bus service will be provided.

The Euronight trais on the Stuttgart - Munchen ↔ Ljubljana - Zagreb will be diverted between Schwarzach im Pongau-St.Veit and and Zidani Most from 26/09/2026 through 14/10/2026.
As a result the train canot make its usual calls in Lesce-Bled and Ljubljana
A replacement train is being arranged between Ljubljana and Lesce Bled.
A rail replacement bus service is being arranged between Lesce Bled and Villach Hbf.

Also from 24/09/2026 through 14/10/2026 the Zurich ↔ Ljubljana - Zagreb service is completely cancelled.

The IC trains would usually be taking Lille ↔ Kortrijk and Lille ↔ Gent - Antwerpen routes.

Until Saturday, October 31st, there are a few departures where you will take the Togbus between Kolding and Hamburg when traveling between Copenhagen and Hamburg.

The changes are due to track work.

From Copenhagen to Hamburg:

The trains ECE 399 from Copenhagen Central Station at 4:22 pm and the ECE 1199 from Copenhagen Central Station at 6:22 pm are cancelled.
The alternatives are to take the regular IC trains to Kolding which depart:
