S-Bahn traffic jam: Major diversions for commuters until November 2025!
In the coming months, commuters between Königs Wusterhausen and Berlin will have to prepare for extensive changes to S-Bahn traffic. How Moz.de reported, the S-Bahn line S46 will be interrupted from September to November 2025. The measures are necessary to carry out extensive signaling work and switch replacements. The affected sections are not only between Königs Wusterhausen and Berlin Grünau, but the regional trains RE2 and RE7 are also canceled for weeks between Berlin Ostbahnhof and Königs Wusterhausen.
Commuters and travelers should prepare for longer journey times and necessary changes to alternative rail services. During this time there will be a total of five dates for rail replacement services, which will particularly occur at night:
- 19. September, 22 Uhr bis 22. September, 1:30 Uhr.
- 26. September, 22 Uhr bis 29. September, 1:30 Uhr.
- 2. Oktober, 22 Uhr bis 6. Oktober, 1:30 Uhr (zwischen Königs Wusterhausen und Berlin Grünau).
- 6. Oktober, 4 Uhr bis 13. Oktober, 1:30 Uhr (zwischen Königs Wusterhausen und Wildau).
- 28. Oktober, 4 Uhr bis 3. November, 1:30 Uhr (zwischen Berlin Grünau und Berlin Baumschulenweg).
What else is there to consider?
The construction work is part of a comprehensive program to improve the S-Bahn network. Loud sbahn.berlin All construction work and the corresponding bus replacement services are listed in the timetable information. It is therefore advisable to always find out about the current timetables before traveling. There are also some short-term changes in traffic that are coming in the next few days, such as the no S-Bahn service between Blankenburg and Hohen Neuendorf from September 8th to September 12th.
You should also pay attention to the route between Königs Wusterhausen and Wildau on the night of September 19th to 20th, as there will be no S-Bahn traffic here either. This affects the nights, which are particularly critical for many commuters. The switch to alternative transport can be planned by using barrier-free buses, which also makes it easier for older people or parents with children.
Conclusion
The coming months will be challenging for many commuters. This makes it all the more important to adapt to the changes in good time and minimize the effects of the construction work. Keep an eye on your timetables so that you are well prepared for the next few weeks. It remains to be hoped that the work will be carried out quickly and efficiently so that S-Bahn traffic can soon flow smoothly again.
