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.

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.

On April 24, 2024, another significant milestone was reached in the construction of the S-Bahn line S4. On this Wednesday, we successfully concluded the hearing for the second construction section which extends from Luetkensallee to the border between Hamburg and Schleswig-Holstein. The hearing lasted a total of three days and was characterized by intense exchange and dialogue with the participants. It was a non-public, oral hearing in accordance with the Hamburg Administrative Procedure Act, conducted by the Hamburg Authority for Economy and Innovation as the hearing authority. We were represented by numerous internal and external experts from Deutsche Bahn as the project developer, and we were able to discuss the interests of all those who submitted objections or statements. Participants included objectors, public interest entities, and authorities.
