Overview
- Reporting based on project insiders says Deutsche Bahn plans a staged in‑service plan with partial passenger relief by end‑2027, the Bonatz building in use end‑2028, the airport connection by end‑2030, and full through‑station opening in late 2031.
- The delay follows an internal review ordered by new DB chief Evelyn Palla that cited serious shortcomings at DB Projekt Stuttgart‑Ulm and unresolved problems in the Digitale Knoten Stuttgart (DKS) digital signalling project.
- Deutsche Bahn has declined to publicly confirm the new timetable and will discuss an in‑service concept at the Stuttgart‑21 steering meeting, leaving schedules provisional for now.
- Officials say the shift will add hundreds of millions of euros per year in extra costs and push related redevelopment of the former rail yard, including the Rosenstein quarter, into the mid‑2030s.
- Regional politicians led by Baden‑Württemberg’s Minister‑President Cem Özdemir have demanded clear, verifiable timelines and answers about the DKS, and have pressed DB for immediate, reliable figures and accountability.
