Mega construction work at Seddiner Bahnhof: RE7 fans have to change!

Seddin, Deutschland - On July 5, 2025, extensive construction work at Seddin station in the Potsdam-Mittelmark district, which is necessary, begins because the tracks of the station have to be completely renewed. These measures confirmed by a spokeswoman for Deutsche Bahn (DB) lead to a blocking of the two tracks from July 4 at 9:30 p.m. The Regional Express RE7, which runs between Berlin Ostkreuz and Dessau (Saxony-Anhalt), is affected by the construction work. Seddin train station is no longer hit during the construction period, as the tracks remain closed until August 22nd.

After August 22, one of the tracks should be released again, but it is still unclear whether the RE7 trains can then drive through. The DB is currently working on information on single -track blocking, which are to be issued by September 19. The football fans among travelers have to plan additional time while replacement traffic is set up by buses between Griebnitzsee and Borkheide.

further construction work in September

From September, there is another phase of extensive construction work on the RE7 route, which affects the connection between Seddin and Bad Belzig. Here, 22 kilometers of tracks and 14 switches are renewed. The train traffic between Seddin and Dessau Hauptbahnhof will be canceled from September 11th to November 24th. Replacement traffic is provided by three bus lines:

• Bus Re7a: hourly express bus line between Dessau Hbf/Bad Belzig and Potsdam Hbf with stop in Roßlau, Jeber-Bergfrieden, Medewitz, Wiesenburg and Michendorf.
• Bus Re7b: hourly line between Michendorf and Bad Belzig, which serves all holds on the go except Baitz.

long -term perspectives and comprehensive renovations

The current work on the RE7 are part of a comprehensive renovation offensive that is to modernize over 40 routes in Germany by 2030. Increasing number of construction sites already leads to significant delays and travel failures, especially in the metropolitan regions. Travelers have to expect train failures and delays of 40 to 90 minutes. This situation affects not only the RE7, but also other important routes in the network.

The DB recommends that you regularly find out about the developments and changes in train traffic, since such construction measures can affect rail traffic both permanently and at short notice. Further information can be accessed via the official platforms and apps. Information on the upcoming construction work is also on the pages of rbb24 , DB Regio and Tagesschau
