The Deutsche Bahn (DB) is implementing a new electronic interlocking system at Munich’s Ostbahnhof during the Pentecost holidays from June 6 to June 18, 2025. While this upgrade aims to modernize digital signaling and control technologies, it brings extensive disruptions to the S-Bahn network during this period. The upgrade process requires meticulous testing, with approximately 8,000 hours of assessments, and will impact commuters over three distinct phases.
The first phase begins on the night of June 6-7 with the complete closure of the main S-Bahn route, as well as connecting tracks around Ostbahnhof extending to Riem, Giesing, Trudering, and Johanneskirchen. Replacement buses will operate at frequent intervals, including every five minutes between Isartor and Ostbahnhof. Most S-Bahn lines will terminate early, with only the S2 and S3 continuing through the central portion between Laim and Isartor. Normal frequency service, including additional trains, will be suspended across all lines. Commuters traveling to Munich Airport are advised to use the S1, which will run every 20 minutes with longer trains during the disruptions.
From June 7 to June 13, during the second phase, S-Bahn tracks near Ostbahnhof remain inaccessible as testing of the system progresses. Replacement bus services have been expanded to assist passengers, while alternative transport options via regional trains, subways, and buses are being recommended for high-demand periods, such as the Nations League Final on June 8. Lines such as S6 and S8 will terminate at Pasing, and others at the Hauptbahnhof or Heimeranplatz. Travelers can find the most efficient routes through mobile apps and station kiosks.
Phase three starts on June 13 and lasts until June 18. At this stage, the entire S-Bahn network affected by the modernization is gradually linked to regular operations. DB experts will monitor the system, ensuring smooth integration while maintaining reduced services near Ostbahnhof. By June 19, full-scale operations are expected to resume, signifying the completion of the upgrade.
During this period, information stations at various terminals will help passengers navigate replacement routes, alongside staff assistance and QR codes for connecting via smartphone. For complete details, passengers are encouraged to visit s-bahn-muenchen.de/baustellen or contact the S-Bahn Munich customer service team.
