cHRONOLOGy of the project
Far more than just a train station: As one of the largest infrastructure projects in Europe, the Stuttgart-Ulm rail project comprises the two subprojects Stuttgart 21 and the new Wendlingen-Ulm line. Find out about the current state of affairs and take a look at the chronology.
Commissioning of the new Wendlingen-Ulm line
The new Wendlingen-Ulm line will go into operation on December 11, 2022. It will enable new and faster connections in regional and long-distance traffic.
All tunnels in the Stuttgart basin completed
On October 5, 2022, all the tunnels for Stuttgart 21 in the basin of the state capital will have been successfully driven. In total, the miners have dug around 51 kilometers of tunnel.
Way clear for the Pfaffensteig tunnel
On July 18, 2022, the project partners in the steering committee clear the way for the construction of the Pfaffensteig Tunnel. This will be a good 11 kilometers long and connect the Gaeubahn to Stuttgart Airport.
Start of construction sidings station
Deutsche Bahn will start construction work on the new stabling yard on July 5, 2022. This is being built on the site of the former marshalling yard in Stuttgart-Untertürkheim.
New cost framework Stuttgart 21
On March 18, 2022, Deutsche Bahn AG announces that the financing framework for Stuttgart 21 currently approved by its Supervisory Board now amounts to 9.79 billion euros. This includes a supplementary provision of €0.64 billion.
Closing the gap in track construction on the new line
On October 27, 2021, the gap in track construction for the new line will be closed on the Filstal Bridge. A good year before the line goes into operation, there is now a complete direct rail link between Wendlingen and Ulm. Almost 120 kilometers of track have been laid - track construction is almost complete.
First rails for Stuttgart 21
The first rails for Stuttgart 21 will be delivered to the Feuerbach tunnel on October 12, 2021. Track construction is now starting there. The more than 50 kilometers of tunnels for Stuttgart 21 in the Stuttgart basin have almost been dug.
Bridge building over the Filstal
On July 14, 2021, representatives of the project partners and the construction company will see for themselves that the bridge over the Filstal valley has been successfully built. At 85 meters, the Filstal Bridge is the third-highest railroad bridge in Germany. It forms the centerpiece of the new Wendlingen-Ulm line.
First overhead line mast for Stuttgart 21
Deutsche Bahn will erect the first overhead line pylon for Stuttgart 21 near Denkendorf on June 2, 2021, marking an important milestone on the way to commissioning the project.
Opening Neckar footbridge
On April 20, 2021, the Stuttgart-Ulm rail project association will open the Neckar footbridge with representatives of the state capital, Deutsche Bahn, the construction company Max Bögl and the ADFC cycling association. The bicycle and pedestrian footbridge attached under the Neckar Bridge is around 4.5 meters wide, almost 170 meters long and runs at a height of over six meters above the Neckar. The footbridge creates an important and environmentally friendly connection between downtown Stuttgart and Bad Cannstatt.
Mountain feast goblet supports

Bad Cannstatt tunnel completed
On February 17, 2020, Deutsche Bahn will successfully complete driving of the 3.5-kilometer Bad Cannstatt tunnel. The breakthrough will take place under Rosensteinpark at a depth of around 13 meters. The miners had been digging the tunnel from various points since March 2014.
Railroad strikes through from the south with first tunnel tube to main station
The railroad arrives at Stuttgart's future main station on February 11, 2020, driving the tunnel from the south. The miners are cutting the first of two tubes at the southern head of the future main station. Driving took just under 15 months.
Stuttgart becomes pilot node of Digital Rail Germany
On January 31, 2020, German Transport Minister Andreas Scheuer announces that the core of the Stuttgart rail hub will be equipped with ETCS and other technologies by the end of 2025. This will allow many more trains to run. This will make Stuttgart the pilot node for Digital Rail Germany.
Denkendorf tunnel shell completed
On December 14, 2019, the shell of the Denkendorf tunnel in the Filder region will be completed. Highway 8 had to be relocated several times. Now it is back in its original position.
S-Bahn tunnel cut under the Rosensteinpark
November 28, 2019: After five months, the miners have finished driving the double-track section of the Rosenstein urban rail tunnel. The S-Bahn tunnel is being built from two directions using the mining method. S-Bahn trains will run in the tunnel between the Neckar Bridge in Bad Cannstatt and the Mittnachtstraße S-Bahn stop.
Tunnel Untertürkheim: Both tubes cut through
On November 15, 2019, Deutsche Bahn will reach an important milestone: The miners will be able to excavate the first of two tubes of the Untertürkheim tunnel in the area of the future rail yard. It took around two years to drive the tunnel. On December 16, the tunnelers succeed in breaking through the second tube.
Machine driving completed at the Filder Tunnel
The "Suse" machine finishes its work. Deutsche Bahn will celebrate this milestone in the construction of the Filder Tunnel with guests of honor on September 9, 2019. With the end of machine driving at the Filder Tunnel, around 110 of 120 kilometers of tunnel tubes in the Stuttgart-Ulm rail project have been driven.
Albvorland Tunnel: End of machine tunneling
The "Sibylle" tunnel boring machine will finish its work on August 11, 2019: In a good 1.5 years, it has dug around 7,700 meters of the north tube of the Albvorland Tunnel. The second machine, "WANDA," will also reach its destination on October 29, 2019.
Last driven pile set for the main station
The last of 2,000 driven piles will be in the ground on August 8, 2019. Together with the base plate, they will later form the foundation of the main station. The future station with its 28 goblet supports stands entirely on these driven piles. Both the floor slab and the driven piles will later bear the loads of the platform hall.
Rails are laid on the Alb plateau: Construction of the first meters of slab track on open track
On August 7, 2019, the railroad will celebrate the start of construction of the first meters of slab track on open track, directly in front of the Alb Abstieg Tunnel, with the "Schwäbische Alb" railroad technology consortium.
Urban planning competition Rosenstein
The Rosenstein urban planning competition ends on July 22, 2019. The jury selects the revised design of the offices "ASP Architekten/Koeber Landschaftsarchitektur" (Stuttgart) as the winner. Thus, the design is decisive for the new Stuttgart district.
Realization and Financing Contract Large Wendlinger Curve
The financing of the second track of the Wendlingen curve is set for May 3, 2019: State Transport Minister Winfried Hermann and DB Board Member for Infrastructure, Ronald Pofalla, sign the contract. The first work begins promptly. The Große Wendlinger Kurve is being built at the interface between the new Stuttgart-Ulm line and the Neckartalbahn in the direction of Reutlingen/Tübingen. It is regarded as an important addition to the infrastructure.

The approximately 30-kilometer section between Ulm and Merklingen is the first part of the rail project to be completed in one piece on December 20, 2018. The 120-meter rails are delivered. At the same time, workers are erecting the catenary masts. The first of 800 masts is placed on December 12, 2018.
First chalice support shell finished
On October 20, 2018, the railroad concretes the first of the 28 cup supports for the main station. This means that the shell of the first, approximately twelve-meter-high part of the future roof with the opening for a light eye is complete.
Neckar river crossed with all four tunnel tubes underneath
October 2, 2018: Deutsche Bahn has successfully tunnelled under the Neckar with all four tubes. The tunnel under the Neckar connects the future main station with the existing tracks in the direction of Obertürkheim. It also connects the future stabling station in Untertürkheim.
Neckar Bridge: Tact shifting work successfully completed
On August 9, 2018, Deutsche Bahn reaches an important milestone in the construction of the Neckar Bridge in Stuttgart: the last cycle of the bridge is successfully completed.
The steel sails of the bridge are pushed into their final position. This takes around three hours. Around 3,100 tons of steel are moved about 15 meters. The steel sails will leave their mark on the cityscape.
In total, the now completed part of the bridge was built and advanced in twelve sections. The first cycle was in August 2017.
West tube of the Filder Tunnel completely excavated
On August 7, 2018, the railroad reaches an important interim goal at the south end of the future main station: jacking machine "Suse" has mastered its third shield run. It arrives in the Stuttgart basin. The west tunnel of the 9,468-meter-long Filder Tunnel is now completely excavated.

The railroad celebrates the breakthrough of the second tube of the Boßler Tunnel with guests of honor on June 8, 2018.
Tunnel on the Alb descent shell completed
The construction companies finish the shell of the Albabstieg Tunnel on May 9, 2018. They pour the last of 945 blocks of the inner shell.
Cost increase and time delay
On January 26, 2018, Deutsche Bahn announces that the Stuttgart-Ulm rail project will be more expensive than planned. In addition, it will be completed later.
Stuttgart 21: The Deutsche Bahn Board of Management proposes to set the total value at 7.705 billion euros. The project is scheduled to go into operation in 2025.
The reasons for the higher costs are:
- Construction prices have risen sharply.
- Tunneling in anhydrite is much more complex.
- Species protection makes permitting procedures more extensive.
- The project will not go into operation until 2025.
New Wendlingen-Ulm line:
The cost forecast rises to 3.703 billion euros. Completion postponed by one year to 2022.
Steinbühl tunnel shell completed
On November 20, 2017, workers pour the last of 777 blocks of the inner lining of the Steinbühl Tunnel. This makes it the first major tunnel on the new Wendlingen-Ulm line to complete its shell.
Christening and start of construction of Albvorland Tunnel
Deutsche Bahn celebrates the start of construction of the Albvorland Tunnel with guests of honor on October 06, 2017. The tunnel and the two tunnelling machines are symbolically christened.
First bridge cycle pushed across the Neckar River
Construction companies push the first section of the new Neckar Bridge across the river in Stuttgart on August 14, 2017. This cycle push is the first of a total of twelve during construction of the bridge.
Federal Railway Directorate "floats
The railroad can begin excavation for the station trough at the northern head of the valley crossing on July 27, 2017. For this purpose, it has temporarily placed the former Federal Railway Headquarters on stilts. This is one of the most technically difficult measures in the project.
In the future, trains will roll under the building into the new main station.
Construction of the first chalice supports begins
Construction work will begin in two phases at the station on March 20, 2017. They are the trademark of the new Stuttgart Central Station.
First breakthrough in the Stuttgart 21 project
On 19.12.2016, the Bad Cannstatt tunnel is cut through. The construction time was only 33 months. The 3,507-meter tunnel connects Stuttgart-Bad Cannstatt station with the new main station.
Penetration at the Alb descent
On November 22, 2016, the project partners will celebrate the breakthrough of the eastern tube of the Alb descent tunnel in Ulm. The new line runs in the 5,940-meter tunnel from the high plateau of the Swabian Alb down to Ulm main station.
First breakthrough of the Boßler tunnel in the Filstal valley
The tunnel boring machine "Käthchen" reaches an important milestone on November 6, 2016: After 8,806 meters, it arrives in the Filstal valley. "Käthchen" has thus completely driven the first tube of the Boßler Tunnel.
Laying of the foundation stone for the new main station
On September 16, 2016, the foundation stone of the main station will be laid. The symbolic act takes place on the first concreted section of the floor slab. Stuttgart's new main station is the central structure of the Stuttgart-Ulm rail project.
Informal citizen participation Rosenstein
In 2016, the city of Stuttgart discusses the future of the future neighborhood with citizens in the "Informal Rosenstein Citizen Participation". The outcome is the "Rosenstein Memorandum". It contains all those aspects that are important to the citizens for the development of the neighborhood and for living together in Stuttgart. The memorandum contains so-called guard rails as recommendations. These serve as a basis for further planning, participation and decision-making processes.
Neckar underpassed for the first time with traffic tunnel
DB Projekt Stuttgart-Ulm GmbH is crossing under the Neckar River for the first time during construction of the Obertürkheim Tunnel. It is the first traffic tunnel ever to pass under this river.

Penetration at the Steinbühl Tunnel
Six months earlier than planned, the breakthrough of the Steinbühl Tunnel will be celebrated in Hohenstadt on November 6, 2015. This marks the completion of the mining work on the first of the eight major tunnels of the rail project.
Second tunnel boring machine goes into operation
"Käthchen" is the name of the machine for building the Boßlertunnnel. It will start work on April 14, 2015. In the first section, the machine digs the east tunnel. This is where the Ulm-Stuttgart line track will later be located. It starts at the Aichelberg portal. From there, the Alb goes uphill.
Agreement on "third track" variant at airport
On March 6, 2015, the partners in the S21 project agree on the "third track" variant for the Filderbahnhof station at the airport. The parties involved are:
- the DB Board Member for Infrastructure, Dr. Volker Kefer
- the S21 project manager Manfred Leger
- the Minister of Transport of the state, Winfried Hermann
- Stuttgart's Lord Mayor Fritz Kuhn and
- Regional President Thomas Bopp.
Federal Railroad Administration approves 7th plan amendment for groundwater management.
The Federal Railway Authority (EBA) approves the 7th plan amendment for groundwater management on September 23, 2014.
This will enable DB Netz AG to hold 6.8 million cubic meters of groundwater in the station area over the entire construction period. This water is collected in the excavation pits. It is extracted, cleaned and returned to the ground.
Archaeological finds in the Middle Palace Garden
Archaeologists dig in the construction field. They discover various archaeological finds in August 2014:
- a channel formed by stone slabs, probably from the 17th century
- several ovens from the Roman period and
- Remains of early Halamannic houses from the 3rd/4th century.
Work for the station trough starts
Construction of the station trough will start on August 5, 2014. This is 900 meters long, 80 meters wide and up to 16 meters deep from the south to the north end. The trough is being built in 25 sections.
Ceremonial start of construction for the Filder Tunnel
On July 10, 2014, project participants and guests of honor celebrate the start of construction of the Filder Tunnel with a tunnel christening ceremony and a symbolic tunnel stop. It is 9.5 kilometers long and will be excavated by mining. A 120-meter-long, 4,200-kilowatt (5,700-hp) tunnel boring machine is being used. A small section in the middle of the tunnel is being excavated conventionally. This means they are excavating, chiseling or blasting.
Ceremonial start of construction for the Albabstieg tunnel
Project partners and contractors celebrate the stop of the Albabstieg Tunnel with a christening ceremony on June 23, 2014.
Tunnel christening of the Ober-/Untertürkheim feeder line
A tunnel christening ceremony on December 4, 2013 marks the symbolic start of construction work on the first tunnel of Stuttgart 21. Construction work on the tunnel entrance to Ober- and Untertürkheim begins. December 4 is an important date for the tunnel builders. It is the holiday in honor of St. Barbara. She is the patron saint of miners and tunnel builders.
Tunnel christening of the Albaufstieg
The ceremonial start of tunnel construction on the new Wendlingen-Ulm line will take place on July 19, 2013, when the Steinbühl Tunnel is opened in Hohenstadt. At the same time, it will be the baptism of the Albaufstieg tunnel. From the engineers' point of view, this is the heart of the future 60-kilometer high-speed line.
Increase in the S21 funding framework
On March 5, 2013, the Supervisory Board approves raising the maximum sum for S21 to up to 6.526 billion euros. This is subject to the proviso that the state and city have a share in it.
The Filder Dialog S21 takes place in summer 2012. In addition to Deutsche Bahn's proposed route, the participants discuss six variants for the airport area (PFA 1.3). As a result, they recommend that the airport road variant be examined in greater depth. In the end, this variant fails. The project partners are not prepared to finance the additional costs. Deutsche Bahn draws the consequences: it returns to the procedure for approving the original application route.
Groundbreaking ceremony for new line
Construction of the new Wendlingen-Ulm line begins with an official groundbreaking ceremony near Dornstadt.
Start of construction of technical building
Construction of an underground engineering building begins at Kurt-Georg-Kiesinger-Platz. This is on the north side of the main station. Access to the station from this side will be relocated.
Start of construction work Mittlerer Schlossgarten
Construction companies prepare the building site in the Mittlerer Schlossgarten. 108 trees are felled. A special machine moves another 68 trees.
Demolition south wing
Construction companies begin demolishing the south wing at Stuttgart Central Station.
The new, green-red state government launches a referendum. Citizens vote on a law to withdraw funding for Stuttgart 21. 58.9 percent of those voting reject it. They thus approve the project.
The project executing agencies award the first contracts for major structures of Stuttgart 21, namely the Filder Tunnel and the tunnels to Unter- and Obertürkheim. The contract amounts to 700 million euros.
The results of the stress test are presented to the public at Stuttgart City Hall. In a session moderated by Dr. Heiner Geißler, proponents and opponents discuss the results. The final report has over 200 pages. In it, the experts give the green light for the rail hub. They also confirm that the new station will deliver the required performance and can even reduce delays. The SMA company prepared the expert report. It is a renowned Swiss institute for analysis of railroad operations.
The state elections in Baden-Württemberg take place on March 27. Although the CDU wins the most votes, a change of government takes place. The Greens and SPD form the state government. Winfried Kretschmann is the first Green politician in the history of the Federal Republic to head the government of a federal state. Because the coalition partners disagree on the Stuttgart-Ulm rail project, they agree in the coalition agreement to hold a referendum.
First tree transplants
One result of the mediation is that trees should be preserved as far as possible. A specialist company is therefore transplanting 16 trees at Kurt-Georg-Kiesinger-Platz. This is necessary for the start of construction work.
Proponents and critics will discuss the project from October 22 to November 30, 2010. Former federal minister Dr. Heiner Geißler chairs the mediation. At the end of the nine meetings, he recommends that Stuttgart 21 continue to be built. However, he proposes improvements. The result of a stress test is to show where the planned infrastructure may need to be adjusted.
Economic efficiency of new line
An expert report classifies the construction of the new and upgraded Stuttgart-Ulm-Augsburg line as economically viable. It is therefore given the highest priority. The report was commissioned by the Federal Ministry of Transport.
First tree felling
October 1, 2010: The first 25 trees are felled in the Mittlerer Schlossgarten. This makes room for the construction of the groundwater management facility. There are fierce protests.
September 30, 2010: Workers erect a construction fence in Mittlerer Schlossgarten. This results in clashes between demonstrators and police. Well over 100 people are injured. The day goes down in the history of the state capital and the project as "Black Thursday.
Tens of thousands of people demonstrate against the project. Stuttgart 21 is a topic in the media throughout Germany.
Demolition north wing
On August 25, 2010, demolition of the north wing will begin at the terminus station.
Action by Bonatz heirs dismissed
Stuttgart Regional Court dismisses Peter Dübbers' lawsuit against the demolition of the side wings of the terminus station. The plaintiff is a grandson of the builder Paul Bonatz.

The tracks in the A1 area are being dismantled. The freight station used to be here.
Opening Tower Forum
The exhibition in Stuttgart's station tower opens its doors. Deutsche Bahn and the city jointly provide information about Stuttgart 21.
Realization competition Stuttgart main station
The realization competition for the new Stuttgart main station takes place. The jury, consisting of a total of 32 jurors, chooses the winner unanimously. It is the design of the office "Ingenhoven, Overdiek und Partner" from Düsseldorf.
Spatial planning decision
The Stuttgart Regional Council concludes the regional planning procedure. The authority confirms Stuttgart 21 with further improvements.
Urban master plan
The municipal council approves the urban development framework plan. 75 percent vote in favor. A total of 200 of the 900 suggestions from citizens are incorporated into the plan.
Open citizen participation
Open public participation is taking place. The topic is: What will happen to the areas freed up by Stuttgart 21? More than 400 citizens draw up 900 proposals on how they envision the new city districts.
Regional planning procedure
A regional planning procedure checks whether a project complies with the objectives and principles of regional planning and state planning. Economic, ecological, cultural and social aspects are taken into account.
In 1996, Deutsche Bahn AG applied for a regional planning procedure for Stuttgart 21. The documents were made available for public inspection in the affected communities at the beginning of 1997.
Urban planning expert procedure
The first ideas for urban development emerge. A competition-like process with ten international planning offices is concluded. A commission recommends that the design by Trojan, Trojan + Neu from Darmstadt be continued. It becomes the basis for the urban development framework plan.
Those involved in the project agree on November 7, 1995, to further develop and promote the project. The signatories are
- the covenant
- the state of Baden-Wuerttemberg
- the city of Stuttgart
- the Verband Region Stuttgart and
- Deutsche Bahn.
Preliminary planning continues: experts are studying the technical and economic aspects. This includes a program of geological and hydrological exploration. Experts confirm at the end that the project is economical.
Public ideas workshop
The city is setting up an ideas workshop on urban development. Any citizen can submit suggestions. The Office of Urban Planning examines them and presents the results in an exhibition.
Deutsche Bahn, the federal government, the state and the city present the Stuttgart 21 feasibility study. It states that "Stuttgart 21 is technically feasible." It "brings advantages for urban development and traffic.
Idea sketch Stuttgart 21
The subsequent project promoters present the outline of ideas for Stuttgart 21 to the media. Participating in the conference:
- the Chairman of the Board of Management of Deutsche Bahn AG, Heinz Dürr
- the Federal Minister of Transport, Matthias Wissmann
- the Minister President of the State of Baden-Württemberg, Erwin Teufel
- the Minister of Transport of the State of Baden-Württemberg, Hermann Schaufler and
- the Lord Mayor of the state capital Stuttgart, Manfred Rommel.
Key features of the idea sketch are:
- connect Stuttgart Airport
- to maintain the main station at its location
- to develop the railroad areas that are no longer needed in terms of urban planning
- to realize a high-speed line on the basis of the Heimerl route, and
abandon the Gaeubahn route from Stuttgart city center to Stuttgart-Vaihingen.
Federal Railroad Expansion Act
The government includes the new construction and expansion of the Stuttgart-Ulm-Augsburg line in the Federal Rail Expansion Act.
There are also plans to relocate the long-distance train station to Bad Cannstatt, for example. For this reason, the Stuttgart City Council unanimously called in 1992 for the main station to remain at its location. The railroad should not outsource long-distance traffic.
Deutsche Bahn presents the report that examines variants for the Stuttgart-Ulm section. It presents the H train path and the K train path. The K-route is a mixed solution. It envisages the main station becoming a through station. It connects the station with a tunnel to Plochingen, where it links up with the existing network.
Gerhard Heimerl is a professor at the Institute of Transportation Science at the University of Stuttgart. He presents the variant later known as the H route. The aim is to improve train traffic between Stuttgart and Ulm. Heimerl's idea is to connect the line with a through station in Stuttgart instead of a terminus. According to his proposal, the new station would be located transversely under the terminus station. The latter will be retained.
Federal Transport Infrastructure Plan
The Federal Transport Infrastructure Plan covers all transport routes for which the federal government raises money. In 1985, the plan calls for the rail network to be extended eastward from Stuttgart. The then new Mannheim-Stuttgart line is to be continued.
