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.

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. 

Our project diary

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!

DB InfraGO AG

We warmly welcome Bernd Homfeldt as our new General Director!

We are delighted to welcome Bernd Homfeldt as the new head of the S4 suburban railway line and the general overhaul of Hamburg–Lübeck as well as Hamburg Central Station and the Verbindungsbahnentlastungstunnel as of 1 November!

With his extensive experience at Deutsche Bahn and his enthusiasm for innovative projects in Hamburg and Schleswig-Holstein, he will support the project team in realising our visions and achieving many milestones in construction and planning.

Bernd Homfeldt has worked for Deutsche Bahn for remarkable 47 years and has already managed and driven forward impressive, forward-looking (major) projects in the past, such as the electrification of the Hamburg–Lübeck-Travemünde railway line or the rail link to the Fehmarnbeltquerung. As a true Schleswig-Hosteiner, Homfeldt already knows the region very well, and not just through past projects.

We look forward to working together!

Invitation to the information evening on area management in construction section 2

Invitation information evening

We look forward to welcoming you to our information evening on area management!

Construction work on the first section of the S4 S-Bahn line has been underway since 2021. Now construction section 2 is also set to progress. But before we start the construction work, we would like to talk to you and inform you about the upcoming area utilisation and associated processes in construction section 2, because: Most of the land required for the construction of the S4 and the associated statutory compensation and replacement measures is privately owned. Deutsche Bahn is compensating the owners and leaseholders of these areas for the respective type of area utilisation.

We would like to explain what is involved at an information evening on area management on Thursday, 14 November 2024 at 6 pm in Room 7 of the UCI Kino Wandsbek, Friedrich-Ebert-Damm 134, 22047 Hamburg.

The space management team will explain the terminology and processes involved in space management and answer any questions you may have. Please note that this event is purely for information and direct dialogue with you and that no individual cases can be discussed or negotiated.

"Area management is one of the basic building blocks in a project such as the S4. In order to work together with you as early and transparently as possible, we cordially invite you to ask us any questions you may have. We look forward to talking to you!" 
– Amina Karam, former General Director S-Line S4 & General Overhaul Hamburg-Lübeck
