We are constructing the new S4 line for you
Amina Karam is the public face of the S4, and she is just as international as Germany's main port city. She joined the project as General Project Director on 1 February 2021. Originally from Morocco, she is now back in Germany after spending several years outside the country, her adopted home. Not only is she fluent in German, Arabic, French and English, but she is also a communicative and hands-on manager who is keenly aware of how important the new S4 is for the entire Hamburg region.

Our S4 project partners
The S4 project is a joint undertaking between the German states of Hamburg and Schleswig-Holstein.
Different ministries and public bodies in these states oversee the building of the new suburban rail line to Bad Oldesloe. We have listed the main contacts here.

Putting plans into action
First, all measures have to be planned and approved. Then we can start the work of putting the plans into action.
To build the new S4 line, we are working with several construction companies that have unrivalled experience and expertise.

Working together for a common goal
A project like the new S4 line between Hamburg and Bad Oldesloe needs to involve a wide variety of people if it is to be a success on every front. These people include planning experts, environmental engineers, construction managers and communications specialists, not to mention employees at external project partners and construction firms. Though we come from very different professional backgrounds, we all share one goal: creating the new S4 line.
If you want to join the S4 team at DB InfraGO AG,
just get in touch with our recruiter Katharina Riethmüller by e-mail.
Alternatively, take a look at our careers portal.
