The project was officially announced in April 1994. Construction work began on 2 February 2010.
In March 2013, total costs were officially estimated at
€6.5 billion, the previous estimate being €4.5 billion in 2009.
[ In March 2022, Deutsche Bahn estimated the total cost at €9.15 billion. Heated debate ensued on a broad range of issues, including the relative costs and benefits, geological and environmental concerns, as well as performance issues.
As of 2019, the start of operation is expected in late 2025, versus an initial estimation of 2019 (made in 2010).

Concept
The concept attempts to combine plans for high-speed links from Stuttgart to other cities with the improvement of local infrastructure and replacement of the current terminal station. The current 17-track station is to be replaced by an underground 8-track through station.
The new tracks are planned to cross below ground at right angles to the northern end of the existing building. Parts of the historic Paul Bonatz

Hauptbahnhof building, the platforms and approach tracks are to be demolished, and the land sold for development.
The plans include new surface and underground lines connecting the station in Stuttgart’s enclosed central valley with existing lines. The Stuttgart–Wendlingen high-speed line running through a new tunnel, the Filder Tunnel, would connect the replacement Hauptbahnhof with a new Filder station

Debate and opposition
The Stuttgart 21 project has been a controversial issue among politicians and local people ever since the idea of a through station for long-distance trains – running under the existing station – was first proposed in the mid-1980s.
Since late 2006, there have been negotiations between DB, the Federal Government, the Baden-Württemberg Government and the city of Stuttgart over the sharing of the costs of the project. On 28 June 2007, a high-level conference was held and adjourned between DB chairman Hartmut Mehdorn, Baden-Württemberg Minister of Finance Gerhard Stratthaus and Stuttgart mayor Wolfgang Schuster
Wolfgang Schuster (born 5 September 1949 in Ulm) is the former Lord Mayor of Stuttgart, Germany, from January 1997 until January 2013. He was the successor to Manfred Rommel and he is a member of the CDU.

. At the meeting, agreement could not be reached over the allocation of construction cost risks.
On 19 July 2007, it was announced by the Federal Government, the State of Baden-Württemberg and DB that the project had been approved. Identified funding sources are: DB (€1,115 million), the State of Baden-Württemberg (€685 million), and the Federal Government (€500 million). The agreement also made provision for possible increases over the €2.8 billion estimate of up to €1 billion, with Baden-Württemberg agreeing to fund up to €780 million and DB agreeing to fund up to €220 million. According to the statement, €2 billion would also be invested in the railway to Ulm, with the total budget amounting to €4.8 billion.

and a variety of citizens' and environmental organisations. The aim was to collect 20,000 signatures and thus force politicians to take the issue to a local referendum. The petition gained 67,000 signatures but political wrangling began over whether the issue could be decided by a local referendum in the first place. Legal experts claimed that, as the project was not being financed solely from Stuttgart coffers, it was not for the city of Stuttgart to make the final decision.
On 11 October 2008, about 4,000 citizens of Stuttgart demonstrated against the demolition of the Hauptbahnhof's north wing. Since the fall of 2009, there have been weekly demonstrations on Monday evenings. On 1 October 2010, the biggest protest so far took place with an estimated 100,000 people taking part in the demonstration against the project.

, one of the architects responsible for the project, cited a 2003 report for calling for a halt to the project, saying the ground in the area is too unstable for large scale underground works. Some critics suggest the cost of the project might rise to €18.7 billion.
Referendum
On 27 November 2011, a referendum was held to decide whether the state of Baden-Württemberg should cease funding for the project. 58.8 percent of the votes cast were against such a withdrawal.
While some consider this proof that a majority is in favour of the project, others point out this might in parts be owed to questionable allegations which were floated before the referendum, e.g. that consequences of a withdrawal in the end might already be significantly more expensive than completing the project; as well as the fact that the wording might have been misleading for some voters (a 'yes' vote would have been in favour of pulling out of the project, and a 'no' in favour of its implementation) although the meaning of 'yes' or 'no' was explained on the ballot.

changed the balance of power in the city council as a direct result of disgruntlement with the controversial Stuttgart 21 rail project. The victory marked the Greens' first majority in a German city with more than 500,000 inhabitants. This meant an enormous loss for the CDU, who had held a majority of seats in Stuttgart continuously since 1972.
The Stuttgart 21 project was a major issue in the state elections held in March 2011. While the CDU again won the largest number of seats in the Landtag
