Overview

• Repairs at a faulty signal at Jannowitzbrücke on the morning of July 11 forced partial suspensions and ten-minute headways on S3, S5, S7 and S9.
• The Berliner S-Bahn has not announced when full service will resume, extending uncertainty for commuters on central east-west lines.
• A day earlier, signal failures at Schöneweide and Ostbahnhof combined with a police operation in Schönholz disrupted ten of the network’s 16 lines.
• Reactive fixes and sporadic security interventions underscore chronic signal box defects that have marred operations since March.
• The network fell short of its 96 percent punctuality goal after reporting a 35 percent rise in delays and a 9 percent increase in cancellations in early 2025.
