Munich S‑Bahn Cuts Service and Reroutes After Laim Signalling Software Fault

DB attributes the disruption to a Laim signalling software error requiring a vendor update with tests planned through late November.

Overview

  • Deutsche Bahn announced long‑term timetable reductions, suspending the S3’s weekday 10‑minute service and limiting the S5 to Kreuzstraße–Ostbahnhof.
  • Replacement buses are running in both directions every 20 minutes as fewer trains can operate between Pasing and Laim.
  • A Stammstrecke closure is set from Friday 22:00 to Monday 04:30, prompting widespread terminations and diversions across the network.
  • Weekend adjustments include S1 ending on surface tracks at Hauptbahnhof or in Moosach at 40‑minute intervals, S2 turning at Ostbahnhof, S3 canceled between Giesing and Pasing, and S6 replaced by buses between Trudering and Ostbahnhof.
  • The first section of the Sendlinger Spange is now available, creating a bypass between Pasing and Heimeranplatz to increase routing flexibility during disruptions.
