Stuttgart 21 railway project hit by soaring costs and new completion delays

Germany’s flagship rail hub, Stuttgart 21, has seen its budget swell from the originally contracted €4.5 billion to more than €11 billion, with some estimates now reaching €14.5 billion. The project, launched in 2010 with an expected finish in 2019, has repeatedly pushed back its deadline – most recently to the end of 2026, and later to 2031 according to the new DB chief Evelyn Palla.

The cost escalation and schedule slips have fueled regular protests since the inaugural ceremony in 2010, when former DB CEO Rüdiger Grube pledged the project would stay on track. Critics, including transport expert Ingo Hansen, argue that the original capacity assumptions – a stress test claiming the station could handle 49 trains per peak hour – were overly optimistic. Palla has said the agency will first conduct a comprehensive evaluation before setting a new timetable.

The controversy underscores broader concerns about large‑scale public infrastructure financing and planning in Germany, as the project remains a focal point for both political debate and civic activism.
