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!

Merry Christmas from the S4 Team!

Merry Christmas and a Happy New Year!

"I am delighted that I was able to take over the management of the S4 project this year. Together we can look back proudly on this year's progress. This includes, among other things, the hearing for construction phase 2, the start of the reconstruction of the Rahlstedt central bus station, the planning approval decision for the S4 individual measure Bargteheide, the start of the trial operation of the MetaWindows, the information evening on area & property management in construction phase 2 and many major and minor construction advances.

But I would particularly like to look ahead and concentrate on the upcoming goals in 2025. Here's to a good collaboration in the S4 team and with you, dear residents!" - Bernd Homfeldt, Head of S4 & General Overhaul Hamburg–Lübeck and Hamburg Central Station &  Verbindungsbahnentlastungstunnel

First things first, let’s get to know each other!

Teamworkshop November 2024

Team workshop at the ICE plant in Hamburg-Eidelstedt with the teams connecting railway relief tunnel and expansion of Hamburg Central Station

For us, a new project management means more than just a new manager, it also means many new colleagues. Bernd Homfeldt not only brought himself to the project, but also two existing teams. These are the connecting railway relief tunnel team and the Hamburg main station expansion team. It was therefore urgently necessary for us to get to know each other and our projects. It was time for a team workshop.
