How much does Stuttgart 21 cost?

Stuttgart 21 is a railway and urban development project in Stuttgart, Germany, that is replacing the surface terminus with an underground through station and tunnels as part of the Stuttgart–Augsburg and Main Line for Europe corridors; construction began on 2 February 2010 under a 2009 financing agreement of about EUR 3 billion plus a EUR 1.5 billion buffer (EUR 4.5 billion). Deutsche Bahn's CEO told the transport committee on 26 June 2026 that total costs rise by about EUR 3 billion to roughly EUR 14.5 billion, with completion of the main station delayed to December 2031, after earlier estimates of EUR 6.5 billion in 2013 and EUR 9.15 billion in March 2022.
