Overview

• A defective interlocking at Bellevue has led to cancellations and delays on Stadtbahn lines S3, S5, S7, S75 and S9.
• Concurrent repair work at Bahnhof Gesundbrunnen is disrupting North–South routes, restricting the S2 ten-minute shuttle between Lichtenrade and Nordbahnhof.
• Maintenance on the southern Ringbahn segment between Südkreuz and Tempelhof has halted most services, leaving only the S46 running every 20 minutes.
• Deutsche Bahn advises commuters to use Regionalbahn, U-bahn or tram alternatives while specialist teams address the signalling faults.
• Ongoing failures in ageing manual interlocking hardware highlight a systemic reliability crisis expected to persist until electronic upgrades begin in 2027.
