Stuttgart 21 delays again: 2031 opening after 1,000 km of faulty cables found
Stuttgart 21’s opening is now officially delayed until 2031 after inspectors found more than 1,000 kilometres of incorrectly installed cables, a defect that will force the replacement of the entire network and add years to a project already notorious for cost overruns and political recriminations.
The revelation, reported by SWR , means the flagship rail hub will not open until a decade after its original 2021 deadline. Baden-Württemberg’s Green-led government, already exasperated by repeated slippage, immediately demanded written timelines for every remaining construction phase. “We need clarity, not excuses,” Ministerpräsident Winfried Kretschmann told reporters in Stuttgart on Monday.
The cable failure is the latest in a cascade of technical and managerial failures that have eroded public trust. A separate investigation by *Die Zeit* shows that the project’s overall budget has swollen by at least €1.2 billion since 2024, while promised regional rail upgrades and social housing linked to the scheme remain unfunded . Transport minister Robert Habeck, speaking in Berlin, accused Deutsche Bahn of “systematic opacity” and warned that further delays could trigger a parliamentary inquiry.
Deutsche Bahn’s board responded by promising a “comprehensive external audit” of all remaining work packages, including the new Stuttgart Hauptbahnhof platforms and the 10-kilometre tunnel to Filderstadt. Yet even optimists now concede that the 2031 date is contingent on no further discoveries. “Every week brings a new surprise,” said Klaus-Dieter Josel, a senior engineer quoted by *Frankfurter Allgemeine* .
The political fallout is spreading beyond Baden-Württemberg. The federal opposition has called for a nationwide moratorium on major infrastructure projects until a new governance model is agreed. Meanwhile, in Berlin, the debate over the capital’s own Hauptbahnhof plaza—currently criticised as “too hot, too grey, too bare”—has reignited questions about whether Germany can deliver complex urban projects on time and on budget .
For commuters and taxpayers, the arithmetic is brutal: every additional year of delay adds roughly €150 million in financing costs alone. With regional elections looming in 2026, Kretschmann’s coalition faces the prospect of campaigning on a promise it cannot keep. “We are not just building a station,” he said. “We are losing credibility.”
