Munich, Bavaria, Germany – Commuters in Munich experienced widespread disruptions across the S-Bahn network on Tuesday evening, January 6th, following a technical fault involving an overhead line near Ostbahnhof. The incident, which began around 8:45 PM, led to considerable delays, partial cancellations, and diversions impacting four key S-Bahn lines: S1, S3, S5, and S6. Deutsche Bahn confirmed the operational changes, advising passengers to anticipate extended travel times.
Overhead Line Repair Causes Widespread S-Bahn Chaos
The core of the problem was identified as a necessary repair to an overhead line in the vicinity of Ostbahnhof. This critical infrastructure failure significantly hampered train movements through one of Munich’s busiest railway hubs, triggering a cascade of service adjustments across the network.
Impact on Individual S-Bahn Lines:
- S1: Services on the S1 line were severely curtailed, operating only between Freising/Airport and Munich Hauptbahnhof. Notably, trains bypassed the Hackerbrücke station. Furthermore, services towards Freising ran non-stop between Hauptbahnhof and Moosach, omitting all intermediate stations.
- S3: The S3 line experienced split operations. Trains arriving from the west terminated prematurely at Pasing, while services originating in the east commenced their journeys only from Ostbahnhof.
- S5: Passengers on the S5 line faced a significantly reduced service, with trains running exclusively between the Kreuzstraße and Giesing stations.
- S6: The S6 line was subject to a major diversion. Trains from Trudering were rerouted via Ostbahnhof to Pasing, completely bypassing the Leuchtenbergring and Berg am Laim stops. Interestingly, services in the opposite direction (towards Ebersberg) maintained their regular route through the Stammstrecke, making all scheduled stops.
As of late Tuesday evening, Deutsche Bahn had not provided an estimated time for the full resolution of the disruption, leaving many commuters uncertain about their Wednesday morning travel plans. The incident underscores the vulnerability of public transport systems to infrastructure failures, particularly in densely populated urban areas like Munich.
Previous Disruptions Highlight Ongoing Challenges
This latest incident is not an isolated event for the Munich S-Bahn. The network has faced a series of challenges in recent months, ranging from technical defects to extensive construction work. For instance, on December 19, 2025, technical issues on an S2 train caused numerous cancellations and delays between Dachau and Ostbahnhof.

Earlier in December, on December 10, 2025, a signal repair on the main S-Bahn line (Stammstrecke) led to delays of up to 40 minutes, impacting lines S1, S2, S3, S4, S5, S6, and S8.

Ongoing construction work for the second main S-Bahn line (Zweite Stammstrecke) has also contributed to a complex and often unpredictable travel environment. Weekends in late November and early December 2025, for example, saw significant timetable changes and replacement bus services due to these construction activities.
