Overview

• Emergency works between Alexanderplatz and Friedrichstraße concluded after midday, yet passengers were advised to expect continued delays and reduced service.
• Only the S9 ran through the Stadtbahn from 10:00 to 14:00 at 20‑minute intervals because a single track was available during the intervention.
• A fault linked to the recurring “Rotausleuchtung” issue was found at Hackescher Markt and was fixed during the works following the taskforce’s monitoring.
• Residual restrictions include a 10‑minute service on parts of the S5 and S75, with some lines shortened or split even after the repair window ended.
• Because the works were announced at short notice, journey planners did not show them, and riders were directed to regional RE/RB services and BVG’s U5, as further short‑notice interventions are expected in the coming weeks.
