Overview
- Repairs to damaged signal installations between Gesundbrunnen and Nordbahnhof are causing widespread delays and cancellations across the network.
- Lines S1, S2, S25, S26 and S85 are running in split patterns, and a shuttle operates every 15 minutes between Gesundbrunnen (track 4) and Nordbahnhof (track 4).
- Ten‑minute service is limited to select sections, including Nordbahnhof–Zehlendorf on the S1 and Nordbahnhof–Lichtenrade on the S2.
- Deutsche Bahn advises riders to use alternatives such as U2 between Pankow and Potsdamer Platz, Ringbahn S41/S42 from Gesundbrunnen to Südkreuz, Bus 247 near the affected segment, and U8 paired with tram M10 or Stadtbahn lines S3/S5/S7/S9.
- Separately, a defective signal at Griebnitzsee and a speed restriction in Marzahn are constraining the S7 to Ahrensfelde–Potsdam Hauptbahnhof, with a ten‑minute interval only between Friedrichsfelde Ost and Grunewald.
