Rahlstedt is Hamburg's most populous district. This requires an efficient mobility service. In order to be able to offer this in the future, a new high-performance mobility hub will be built around Rahlstedt station in the coming years. Work on the bus system has just begun. The facility will be demolished and completely rebuilt by summer 2026. From the end of 2027, the new S-Bahn line 4 will also stop here. HOCHBAHN, Deutsche Bahn, the Free and Hanseatic City of Hamburg and the Wandsbek district are working closely together on this major joint project.

The S4 has been awarded - and now also with two prizes!

At the international congress of the ICPMA (International Construction Project Management Association) from June 22 to 25, the S4 urban rail line project in New York received two awards: for project management, public participation and communication as well as for one of the best presentation films.

Click here for the video.

S4 General Project Director Amina Karam: "I am very proud that our little S4 from Hamburg and Schleswig-Holstein is now causing a sensation worldwide and here in the Big Apple. We are part of an international network. Together with the two states of Hamburg and Schleswig-Holstein, we will benefit greatly from these contacts. This award is something like the mobility Oscar in our industry. It motivates us for the tasks ahead and will give us a tailwind."

First electricity pylons for new S4 in place

Pressetermin mit Senator Tjarks

DB InfraGO AG

Many media representatives came to see the current work on the construction site.

The construction work for the new S4 S-Bahn line is making great and visible progress. The focus is currently on the electrification of the future S-Bahn line and the construction of the new mainline railway line running alongside it. To this end, 13 new overhead line masts have already been erected and around 2,000 meters of contact wire installed in the area of the construction site between Hasselbrook station and Claudiusstraße. In total, the electrification of the S4 will require 30 new pylons and around 5,000 meters of cable. The S-Bahn trains in Hamburg run on 100 percent green electricity - this will also apply to the S4 from 2029. Since 2010, the Hamburg S-Bahn has saved more than one million tons of CO2 compared to the normal electricity mix. That is equivalent to the annual emissions of 95,000 cars.

S4-arena in Ahrensburg - communication at eye level

S4 Team

DB InfraGO AG

Overall Project manager Amina Karam and the S4-team

200 people from Ahrensburg came to the Peter-Rantzau-Haus in summery 30 degrees Celsius to discuss the most important topics of the S4. The main topics were: Noise protection, Stellmoor tunnel valley as well as construction logistics in the city. "My team and I take these issues very seriously. That's why we have developed alternative proposals that we believe will be an improvement for the citizens," explained overall project manager Amina Karam. The S4 is being built for the people, not against them.

From Karam's and DB's point of view, the aim of the evening was to get into a real conversation with the people of the city. To this end, DB designed a new dialog format. Chairs and bar tables were set up in a circle in the hall for the event's guests. Moderation and project management operated from the center of the hall. "We want to show people that we are talking to them at eye level. We succeeded very well in doing that," Karam explained. The exchange with the peple from Ahrensburg lasted two and a half hours - a marathon.

Ute Plambeck, Amina Karam and Anjes Tjarks lift an element of the first noise barrier for the S4 together with the construction company.

Taking big steps towards the mobility shift: DB is building the first tracks and noise barriers on the S4 in Hamburg. More than 6,000 households will benefit from the new noise protection in the first construction phase alone. DB is reducing the noise by 20 decibels with noise-protection windows, soled railway sleepers and noise-protection walls. With a reduction of just ten decibels, people perceive the noise as only half as loud. The new urban railway line connects Hamburg's east with Schleswig-Holstein. DB Representative Ute Plambeck and Hamburg's Transport Senator Anjes Tjarks were on site today and gave the go-ahead for the construction of the first noise barriers.

The lifting of the bridges early Saturday morning on the S4 construction site

In order for construction to continue at full speed and for trains to be able to roll along the long-distance railway tracks without major closures next year, Deutsche Bahn (DB) is optimising the construction process for the S4. During a site visit in Hasselbrook today, Hamburg's Senator for Traffic and Mobility Anjes Tjarks got an idea of the creative solution - two 27-metre-long steel bridges. Until the actual structure over the freight bypass is built at the site, DB is using two bridges from its existing stock. Experts installed them in record time over the weekend with the help of a 700-tonne crane.

Get a taste of practical experience: 
a visit to the S4 construction project

Those who regularly follow the construction site camera were recently able to discover something else on the construction project besides the usual work: 17 people, equipped with orange safety jackets and helmets, inspected the site on Hammer Straße. DB trainees from all over Germany and colleagues from the Hamburg railway project "Verbindungsbahnentlastungstunnel" (VET) visited the S4 project.

Marian Mischock, 30, a trainee in the infrastructure planning department in Berlin, was happy about the excursion into practice: "We all come from different backgrounds. During my studies of transport economics, I mainly dealt with the theoretical basics of the economic evaluation of transport projects. I am very happy to get to know a transport project at close quarters today".

More than 250.000 people will benefit from the new S4. It creates a strong rail connection between Hamburg and Schleswig-Holstein. Passengers can look forward to a wider range of services and new direct connections.

But what does the project mean for Europe? Quite a lot! The S4 lies on the main transport corridor between Scandinavia and the Mediterranean. The project allows metropolises to grow closer together, creating new living and working spaces. In June, the project was presented at the Connecting Europe Days in Lyon.

S4 Christmas card

S4 project team

An exciting and eventful year is now drawing to a close. The S4 project reached several milestones over the course of the past 12 months. In spring, there was the groundbreaking ceremony to mark the start of the S4's first construction phase. Another high point came when Germany's top administrative court ruled against all of the legal challenges brought against this part of the project. After this final ruling, we can now press ahead with our plans.

The entire project team is delighted to finish the year on such a positive note. Enjoy the festive season, and we hope that 2022 gets off to a great start for you.

Vegetation control for the S4 – on tour with an environmental expert

Wherever the new S4 line has an impact on nature, conservation is always a top priority for the project team (source: Planungsgemeinschaft LaReG).

Wherever the new S4 line has an impact on nature, conservation is always a top priority for the project team.

Specialists started the job of trimming and clearing vegetation between the stations at Hasselbrook and Luetkensallee on 20 October 2021. The S4 environment team is always involved in the action.

Environmental and resource management expert Laura Schneider is part of this team. The 33 year-old project engineer focuses all of her energy on her job of protecting the environment during the construction project. To her and everyone else on the S4 team, conservation is a personal mission. "It is important to us that our work doesn't endanger plants or animals, such as the bats that live near the line," she says. Tree hollows are popular with bats because they provide refuge during winter, so checking trees for occupants is a key element in our conservation work. The S4 environment team uses a sheet of fabric to seal unoccupied hollows, while a special exit-only opening makes sure that any bats that might still be inside can get out unharmed. Thanks to this measure, we ensure that the animals cannot inadvertently pick trees slated for removal as their home for the winter.

The S4 is coming: 
Germany's top administrative court rejects all legal challenges.

The Federal Administrative Court today dismissed all actions brought against the first section of the new S4. The court ruled that the plans and planning approval decision for the project were final and that there were no procedural irregularities in the decision. Similarly, the court found that there were no legal errors in the assessment of different routing proposals, and it issued a positive preliminary judgement regarding conservation issues as "there are no insurmountable obstacles arising from conservation legislation".

Noise from construction sites and how to shield nearby residents

Outdoor microphone

Krämer Evers

Microphones installed around the building site monitor noise levels.

Large construction sites like the S4's inevitably generate a lot of noise and vibrations. Before building starts, DB produces a noise forecast that includes the maximum range of noise emissions' transmission. The forecast incorporates site-specific features such as topography, surrounding buildings and the construction machinery that will be in use. In addition, the noise experts study the nature of the work and how long construction will continue.

A mammoth on the move

RPM

DB Netz AG

The formation rehabilitation machine in action for the S4.

Measuring 200 metres and weighing 800 tonnes, the giant among rail construction machines recently went to work for the new S4. Its mission was to renew the line's tracks between Hasselbrook and Wandsbek station. This formation rehabilitation machine is a real multi-talent.  Inch by inch, it lifts the rails and sleepers and then scoops up the ballast underneath. This enters the machine, where a complex recycling process treats the material and then deposits it on the track again. The ballast is then tamped back into place so that the rails once again sit on a secure and safe foundation.

S4 EXTRA – part 2: Kupfermühle station gets a complete makeover

Platform 1

DB Netz AG/S4 project team

The S4 project not only consists of three planning approval sections, but it also encompasses various stand-alone measures. It is the combination of these two aspects that will ensure the region's local transport network benefits in full from the new S-Bahn line. Our S4 EXTRA series describes some of the specific measures we're planning and working on outside of the three main construction phases. The first part looked at the upgrade of Bargteheide station. Today, we want to talk about the stop at Kupfermühle.

Construction preparations enter the home straight

Lowering the temporary bridge into place

250,000 people in and around Hamburg will benefit from the new S4. Deutsche Bahn is therefore making some more preparations on the Hasselbrook–Luetkensallee section of the route before construction is due to start in spring. These include vegetation management and clearing at Wandsbeker Gehölz park, removing two level crossings and installing a new temporary bridge over Hamburg's freight bypass line.

Over the next few weeks, anyone travelling along the route of the future S4 will notice pink posters everywhere. They're the signal that the S4 is on its way!
Shortly before the construction stage starts, we will ramp up our visibility in a major way.

Whether it's serving an intercity or suburban route, a train needs more than just a track for it to run. Deutsche Bahn's infrastructure also includes all kinds of technical equipment – the things that are essential so rail services operate smoothly and safely.

To give you an idea of how the S4 might ultimately look, we project engineers make use of the latest advances in digitalisation. This is the obvious technological solution for special tasks of this kind.

Planning documents go on display for planning approval section 2

The new S4 will run between Hamburg and Bad Oldesloe. The formal planning approval procedure for section 2, between Luetkensallee and the border between Hamburg and Schleswig-Holstein, has now started, and the relevant documents are available for public viewing.
This stage is an essential element of the construction approval process, and ordinary citizens now have the opportunity to scrutinise section 2's planning documents as part of the formal public participation stage.

Public display starts of planning revision documents for planning approval section 1 (route and light levels report)

The planning revision documents for section 1 go on public display at two local government buildings on 25 September 2019. The documents will also be available online. In 2018, the early stage of the public consultation process entailed a large number of discussions and a meeting with people living along the planned rail line. Following on from this, the project team has spent the past few months focusing on one particular issue for section 1: plans in the vicinity of the new rail route.

A new milestone in the S4 project

Germany's transport ministry has designated the construction of the S4 line between Hamburg and Bad Oldesloe as a central priority in the country's national transport plan for 2030. This will mean additional support (including financing) for the work of the planning team overseen by project manager Bettina Gnielinski.

On Wednesday, 11 July 2018, our infobus for major projects was in central Ahrensburg to give the town's residents the chance to learn more about the S4. Lots of people were interested in the project so, despite the occasionally heavy rain, they turned up to see what the (sheltered and dry) interior of the bus had in store.

No asset operator, no S4! The role that route asset management in Hamburg plays in the project.

Station

Michael Hibner, route asset manager for Hamburg, DB Netz AG

When people talk about the construction of the new S-Bahn line, the S4, DB Netz AG always comes up as the party in charge of seeing the project through. But who actually owns the line once it has been completed? And who will see to its upkeep, ensure that rail services are punctual and safe, and make sure that planners address all of the concerns of the maintenance and operations staff?

There's more to this than tracks and trains

Knut Marscholek-Uecker, Construction and Facility Management, DB Station&Service AG

The S4 is a suburban rail service. It wouldn't be a service if it didn't transport passengers. There's only one way for the passengers to board the S4's trains: at the stations. In other words, stations are just as important as the trains and tracks.

Just how does the S-Bahn's electricity supply work, and what is the S4's special feature?

Trains on the S4 line will be able to use both direct current and alternating current.

Simon Diestel, DB Energie GmbH

Ever since the 1930s, Hamburg's suburban trains have run on 1,200 volts of direct current. They get this power from what is known as a third rail, a conductor installed beside the running rails. A "collector shoe" mounted on each vehicle connects to the third rail. At present, there are 26 converter stations next to S-Bahn lines throughout Hamburg, i.e. one roughly every five to six kilometres. They convert 25,000 volts of alternating current into 1,200 volts of direct current which can be fed into the third rails.

S4 panel discussion focuses on freight transport

Lively interest: around 140 guests came to the panel discussion in auditorium 8 of Wandsbek's UCI cinema complex

Lively interest: around 140 guests came to the panel discussion in auditorium 8 of Wandsbek's UCI cinema complex

On Monday 23 October 2017, around 140 guests gathered at auditorium 8 of Wandsbek's UCI cinema complex to discuss the S4. Freight transport was the main topic of the evening. DB Netz AG invited people living near the new line and other interested parties so we could clarify their questions. The participants also got the chance to exchange views with the project's experts. That was the clear from the moderator's introduction: "We want to look at your concerns in depth and from different angles."

Now it's your turn...

S-Bahn station

Cordula Kropke

...to say what you think. A woman who takes an interest in our S4 blog and commutes using the RB 81 line (which the S4 will largely replace) recently took the time to tell us how she sees the plans for the new suburban rail service. Her observations are like short stories, complete with a hint of humour, amusing turns of phrase and details from her personal life. They're well worth sharing, so we've added two of them to our blog today.

"Day-to-day stuff" 

If anyone ever asks us what we're currently working on, our team is banned from answering "Oh, the usual day-to-day stuff." All the same, that's what I'd like to talk about in this blogpost.

I'm a "peng", or project engineer, and I'm part of DB Netz AG's project management team for the S4 link between Hamburg and Bad Oldesloe.

I work in Hamburg, yes, but what do I actually do?
