More convenient, more efficient and more punctual
Passenger numbers on northern German rail services have risen sharply in recent years, and the necessary mobility turnaround is expected to lead to even more people switching to rail in the future. To make this possible, the infrastructure at the Hamburg hub is being massively expanded. Passenger numbers have also been rising steadily for years on regional services between Hamburg, Ahrensburg and Bad Oldesloe. We are responding by constructing the S4. This new S-Bahn line will provide the region's inhabitants with better local transport between Hamburg and Bad Oldesloe. Some 250,000 people will benefit from this new service.
Protecting flora and fauna is of vital importance to Deutsche Bahn and all of our project partners. Together, we have designed a range of measures along the route that will safeguard water and soil quality as well as protect the existing landscape. We are working to ensure that the new S-Bahn does not pose a threat to endangered species such as the great crested newt.
The plans for the S4 line include comprehensive active and passive noise mitigation measures, such as trackside barriers and a host of other features. Our website contains detailed information about these and about how our work will change noise levels along the line.
We want you to have the most comprehensive information possible about the S4. What is the current status of the project plans? When will construction work start? And what impact will the project have on people and nature? We have identified the key questions about the project and now have the answers for you.
In-depth information about the planning process and our construction work
20 kilometres of existing line from Hasselbrook to Ahrensburg-Gartenholz will be upgraded for the new S-Bahn service. The project consists of three sections. Each of them has its own specific planning procedure, which means separate approval is necessary for every section.
There's a lot happening when it comes to the planning and construction of the new S4. Our project diary keeps track of the latest developments and follows how the project is going. Members of the project team also provide details about their work so you know more about what's happening in the background. It's a mine of interesting information. Enjoy!

A sunny Friday, 6 hours construction site and 45 interested guests – “Railway Day” at the S4
DB InfraGO AG
Interested citizens explore the construction site together with the S4 team
On Friday, September 20th, as part of the nationwide “Tag der Schiene 2024” (Day of the Railway 2024), we organized three construction site tours in the first section of the future S-Bahn line S4 for the public. The demand was high, and the tours had been fully booked for weeks. However, more regular public tours are planned to occur soon, and we will, of course, keep you updated here.
The "Tag der Schiene" at the S4 was a joint project between the stakeholder management team, the technical project management, and the construction supervision. Together, we guided three different groups of visitors across the construction site, showcasing our latest and most impressive progress: a newly installed auxiliary bridge (one of the longest in Germany), new tracks, noise barriers at the Horner Bogen, and retaining walls driven several meters deep into the ground to form the foundation for the flyover structure.
Additionally, there were three information booths where project data and facts were presented. The posters enabled us to help our guests visualize how the area will transform from a large construction site into a state-of-the-art rail network.
A heartfelt thanks goes to all visitors, who brought the event to life with their active participation and curiosity. We were especially pleased to see the diversity of our guests: from local residents along the new S-Bahn route to technology enthusiasts, from teenagers to seniors, everyone was represented.
“We are especially pleased that we were able to give participants an up-close look at the complex construction processes. Events like this are crucial for creating transparency and making progress visible and tangible for everyone. Thank you for your visit!”

The visit began with a presentation in the construction office, which facilitated a very constructive and interesting exchange. Our guests asked many relevant questions, which led to a lively discussion, which we greatly appreciated. This was followed by a tour of the construction site, during which we were able to present the progress made compared to the previous year.
We would like to thank everyone for their visit and the stimulating dialogue and are already looking forward to next year.

Together We Are Strong: Build the S4 with Us!
Engaging with the residents is a central and vital part of our mission. Our goal is to build the S4 railway line not just for the citizens, but with them. This means actively involving them in the project. We strive to explain what to expect and address their needs as much as possible. To achieve this, we offer exciting construction site tours, personal meetings, our interactive Info Train, as well as our email and citizen hotline.
We frequently welcome various groups to our construction site, including students from different universities, associations, representatives from the states of Hamburg and Schleswig-Holstein, and various departments of Deutsche Bahn. Recently, in April and June, we hosted the Akademie für Raumentwicklung in der Leibniz-Gemeinschaft (ARL) and enthusiastic students from the Technische Hochschule Lübeck at our Hammer Straße site. Visitors received tailored presentations in the construction office, explaining the need for the S4, the project's goals, and its detailed implementation. On-site, they could see firsthand how the flyover structure, noise barriers, and tracks are being constructed. We greatly appreciated the interest and active participation shown through questions and discussions!

We also greatly value personal meetings with citizen initiatives, affected institutions, and individuals at our office or on their premises. These meetings allow us to delve deeper into their questions and needs regarding land usage, construction logistics, environmental concerns, and more. Through these discussions, we learn about the existing conditions, limitations, and opportunities, enabling us to consider both sides and find the best possible solutions. These constructive dialogues help us optimize the project and create win-win situations for all parties involved.
