Overview

• Deutsche Bahn moved the planned opening of the Diebsteich through-station to the end of 2029, targeting the December timetable change after a two-year slip.
• Asbestos and lead found in the Langenfelde crossing structure make demolition more complex under strict legal rules and require specially qualified inspectors.
• DB currently estimates project costs at €550–600 million, says financing is secured, and notes final figures could change as remaining contracts are tendered.
• Passenger services will continue at the existing Altona terminal, where DB is keeping infrastructure in service and carrying out renovation work already underway.
• DB says commissioning a new electronic interlocking and related signaling upgrades is a prerequisite for building new platforms, with an accessible S‑Bahn entrance at Diebsteich expected next year and further platform work running into 2026.
