Overview

• An official groundbreaking at Ostbahnhof marked the start of the east section, putting the entire Laim–Leuchtenbergring corridor into active construction.
• The east segment adds a new München‑Ost station about 16 meters underground and carries roughly €1 billion in investment, with up to 1,000 workers assigned.
• Tunnel‑boring machines over eight meters in diameter will drive about three kilometers of tunnel, including beneath the Isar, alongside a separate rescue and inspection tube.
• The full scheme spans roughly ten kilometers with multiple deep stations, with DB planning entry into service between 2035 and 2037 after years of delays and cost increases.
• Overhead‑line repairs on Oct. 20 between Leuchtenbergring and Ostbahnhof caused delays and reroutings, including a morning S20 cancellation, with further night‑time schedule deviations expected through late October.
