Overview

• Deutsche Bahn reopened S-Bahns between Frankfurt-Ostendstraße and Offenbach-Ost at 05:00 after a full shutdown since July 4.
• A train defect on Monday morning halted services on lines S1, S2, S8 and S9, causing widespread delays.
• The €180 million overhaul encompassed track and switch repairs, tunnel emergency lighting, fire-protection upgrades and station renovation at Frankfurt-Mühlberg.
• Passengers relied on replacement buses and rerouted trains via Offenbach Hauptbahnhof during the extended closure.
• Further night-time and autumn-holiday closures are scheduled from October 2 to 20 to complete the remaining upgrade work.
