Where Rail Passengers Face Disruptions in Berlin and Brandenburg in 2025?

In a year of radical change for passengers, rail services in Berlin and Brandenburg promise a future that will make it easier to get around the area with better service connections. All this, of course, requires local disruption until the end of 2025. DB followed up its Riedbahn renovation success story by announcing further wide-ranging modernisation projects. For instance, routes have been upgraded in the high-speed sector, as well as major stations. This guide will give an overview of the major construction projects and their expected impact on rail travel in Berlin and Brandenburg.

General Renovation Between Berlin and Hamburg

One of the largest and most influential projects is the reconstruction of the Berlin-Hamburg high-speed connection, an important route both for regional traffic and international traffic. Starting in August 2025 and lasting for nine months, the renovation is going to be a high-performance corridor, and work is scheduled for conclusion in April 2026.

Key improvements include: 

• • Installation of state-of-the-art control and safety technology to increase operational reliability.
  • Additional tracks are constructed for overtaking sections so that trains may pass through at a higher speed.
  • Expansion of Wittenberg station to accommodate increased passenger and train traffic.
  • Provide along the railway and extend 5G mobile coverage to ensure unbroken connectivity among passengers.

This project follows the smaller renovation closure of the route in 2024 and is a significant step toward making the transportation link between Berlin and Hamburg faster and more reliable.

Dresdner Bahn Extension Nears Completion

The other major project is Dresdner Bahn, which will be completed by 2025. This route runs from Berlin to Dresden, and extensions are being planned to increase travel speeds and provide better access to other major cities, such as Prague and Vienna.

Important milestones for this project include:

• • Completion of the section between Berlin Hauptbahnhof and Blankenfelde, which is scheduled before the December timetable change.
  • Further reconstruction of stations at Blankenfelde and Zossen in the Teltow-Fläming district.

The project’s completion will enhance regional and international connectivity, benefiting both daily commuters and long-distance travelers.

Berlin Hauptbahnhof Construction Plans Canceled

Plans for a significant renovation of Berlin’s central station (Berlin Hauptbahnhof) were announced in late 2024. These plans included a partial closure of the station from mid-February to April 2025. However, Deutsche Bahn later overturned these plans, citing logistical challenges.

Despite no major construction, overcrowding on the upper-level platforms of the station, especially platforms 13 and 14, remains a problem. Deutsche Bahn has recognized these issues but has dismissed the idea of immediate expansion or reconstruction projects due to logistical constraints.

S-Bahn Disruptions and Renovations

Throughout the year, works are to continue renovating and restructuring the whole Berlin S-Bahn network-a core part of Berlin’s public transportation. From June to September, there are heavy works undertaken, which impacts on the operation of the: 

• • S1, S25, and S85 lines running along Wollankstraße.
  • S2 and S8, along the lines running within Blankenburg area;
  • S2 from the Southern network section
  • S3 around Köpenick / Hirschgarten areas.
  • S45, S46, S47, S8, S85, and S9 in the Baumschulenweg – Schöneweide – Adlershof area.

Further construction:

• • Installation of a new signal box at Südkreuz station, with the north-south long-distance railway tunnel being closed between October and December.
  • Construction at Köpenick station, which is being converted into a regional bahn (RE) connection point. This construction work is to be completed by 2027 for the RE1 line.

The passengers are advised to plan alternative routes and allow extra travel time during these disruptions.

Projects in the Surrounding Regions

Several construction projects in areas surrounding Berlin and Brandenburg will also affect travel:

1. 1. Rathenow:  Stendal Main Line: Repairs will take place from late May to mid-December, although the high-speed line is expected to be operational throughout this period.
   2. Ostbahn (Strausberg to Müncheberg): Scheduled work from late April to early July will impact this regional line.
   3. Wiesenburg (Mark) to Roßlau (Elbe): Repair works are planned from late June to early September.
   4. Prignitz Express Dam Renovation: This project is going to affect the Neuruppin to Kremmen section, and will also impact the Velten section, from August.

How Passengers Can Prepare

The company should update its passengers on such projects so that they can make necessary traveling arrangements in advance. Deutsche Bahn is to provide real-time information and other means of transport to minimize the impact.

Passengers should know this:

• • Monitor announcements: Passengers should keep visiting Deutsche Bahn’s website or mobile application to get the updates on affected routes.
  • Plan alternative routes: Through public transport apps, find the alternative means of transport while these construction periods are going on.
  • Additional travelling time: Consider possible delays in planning your visits.

Long-term Effects of the Upgrades

All the inconveniences during this period in 2025 will be overshadowed by the long-term advantages these projects will bring. The final outcomes will be:

• • Travel times will be faster: Trains will travel faster, and they will not take long to get from one place to another.
  • Higher connectivity: Regional as well as international routes will increase; it will make Berlin and Brandenburg more reachable.
  • Modernized technology upgrade includes 5G coverage and sophisticated control systems to ensure comfort and safety of the passengers.

By 2026, Berlin and Brandenburg’s railway will be better poised to deal with increasing passengers, ensuring smooth travel for its clients.
