Closure of the RE7: Seddin's train station will be modernized from July 2025!
The construction machines are expected to start rolling out again at Seddin train station from July 5, 2025. Tracks 1 and 2 of the RE7 line will be completely replaced, which will result in a complete closure until August 22nd. With the start of the work, not only a massive intervention in rail traffic is expected, but also significant restrictions for commuters from Bad Belzig, Brück, Borkheide and Beelitz who rely on this traffic. The maz-online.de reports that passengers will be offered a rail replacement service should be made available, but detailed information is still pending.
The upcoming construction work includes not only the replacement of rails and sleepers, but also a thorough cleaning of the bedding. These modernizations are part of comprehensive renovation measures at Seddin train station, which include new elevators, benches, modern LED lighting and a new passenger underpass. Many commuters, like Katrin Glamann from Borkhei, express their dissatisfaction with the lack of communication from those responsible. Single father Paul Vielhauer also sees the situation critically: The new circumstances could pose massive problems for his son, who commutes to school.
Further effects of the lockdown
After the first phase of construction work, track 2 will remain closed until September 19, 2025. This could significantly extend commute times, which also has an impact on Vielhauer's company, whose employees regularly have to travel from Potsdam. The rbb24.de highlights that the construction work could even last until 2026, which poses a constant challenge for commuters and travelers.
Nevertheless, there is also a positive ray of hope: Deutsche Bahn is investing extensively in the rail infrastructure in order to improve the quality of rail transport in the long term. As part of the “S3” renovation program, over 53 billion euros will flow into the modernization and maintenance of railway lines and stations by the end of 2027. [deutschebahn.com](https://www.deutschebahn.com/de/presse/suche_Medienpakete/Sanierungprogramm-S3-DB- defines-Massnahme-fuer-bessere-Infrastruktur-bis-2027-13127506) reports that, among other things, 400 train stations will be made more customer-friendly and soon more than 100 train stations will be updated annually.
Conclusion
The renovation work at Seddin train station is an important but also challenging project for commuters on the RE7 line. While the first steps towards improvements are being taken, those affected are hoping for a good hand from the railway so that the upcoming construction work runs as smoothly as possible. Communication about travel options and timetable changes remains essential in order to minimize inconvenience for all commuters.
The upcoming work is not only a sign of necessary maintenance, it also offers the opportunity to sustainably improve rail connections in the region. It is to be hoped that the measures now launched will increase both safety and comfort when traveling in the long term.
