=== Rail: The ''Stuttgart 21'' project ===
After years of political debate and controversy, plans were approved in October 2007 to convert the existing above-ground [[Stuttgart Hauptbahnhof|main train station]] to an underground through station. The ''[[Stuttgart 21]] project'' will include the rebuilding of surface and underground lines connecting the station in Stuttgart's enclosed central valley with existing railway and underground lines. Building work started in 2010 with controversial modifications to the Hauptbahnhof and was slated to be completed in 2019, then 2021 and now 2025.
