Overview

• Deutsche Bahn says a cable was damaged during construction between Hamburg Hauptbahnhof and Altona on Wednesday afternoon, with effects expected at least until Thursday morning.
• Long‑distance trains are turning at Hamburg‑Harburg, with services to and from the south running only hourly and operating only to or from Harburg.
• Regional services are curtailed, with RE7 from Flensburg and Kiel terminating in Neumünster and RE70 from Kiel ending in Altona.
• Metronom trains continue to reach Hamburg Hauptbahnhof, while S‑Bahn operations are not affected.
• The disruption highlights chronic capacity constraints at the century‑old hub, where a comprehensive rebuild is slated to start no earlier than 2028 and the new Altona/Diebsteich station is now targeted for 2029.
