Overview
- Cologne Hauptbahnhof will be largely bypassed from 13 to 24 November for the switchover to an electronic interlocking, with many regional and long‑distance trains diverted to Köln Süd, Messe/Deutz or Ehrenfeld while S‑Bahn lines continue.
- Berlin faces a disruption‑heavy weekend with Ringbahn closures and further outages on S3, S8 and S85, and the regional RE2 is replaced by buses between Lübben and Cottbus through 5 December.
- Dresden rail works from the evening of 7 November to 17 November split or truncate several lines around Hauptbahnhof and Neustadt, with extensive replacement buses on the Freital corridor and timetable changes on RE50, RB30 and RB31.
- Frankfurt’s northern S‑Bahn lines S3, S4 and S5 are suspended from 7 to 19 November, followed by restricted service and replacement buses as switch and overhead line work continues toward 3 December.
- Through RE1 trains between Magdeburg and Berlin have restarted in a limited pattern and will run hourly from 17 November until the 14 December timetable change, with some stops skipped and longer journey times.
