Construction work for new S-Bahn line S4 is progressing

Construction on the eagerly anticipated S-Bahn line S4 is picking up pace

The construction of the new S-Bahn line S4, linking Hamburg-Altona and Bad Oldesloe, is gathering momentum. According to Deutsche Bahn, 13 overhead line pylons have been erected between Hasselbrook station and Claudiusstraße in Hamburg, with around 2000 meters of contact wire being installed. A grand total of 30 pylons and approximately 5000 meters of cable are required for the electrification of the S4.

Alongside electrification, a staggering three kilometers of new tracks for both the S-Bahn and long-distance railroad have been laid, ten new points installed, and 400 meters of new noise barriers constructed. In the coming year, two new bridges and additional noise barriers over more than two kilometers of track are expected to be erected.

Transport Senator Anjes Tjarks (Greens) hailed the S4 as a key rail artery in the north and a pivotal local transport project for Hamburg. DB's overall project manager Amina Karam confirmed that the construction is on schedule and within budget. The S4 is slated to commence operations in 2029, serving approximately 250,000 commuters daily. Five new stations will be constructed along the route, along with the S-Bahn line. The estimated cost of the project is around 1.8 billion euros.

Once completed, the new S-Bahn line S4 is projected to drastically reduce traffic on local roads due to its enticing allure to commuters, transitioning them from their vehicles to the rail network. However, in the interim, local railway traffic disruptions may be experienced due to the construction activities.

Enrichment Data Integration:

The planning stage of the S-Bahn line S4 construction project between Hamburg-Altona and Bad Oldesloe has encountered a few setbacks. Here's an update:

1. Planning Delays:
2. The planning process for the new S-Bahn line S4 has experienced delays of a few months due to the necessity to revise parts of the blueprints. This process involves optimizing plans to minimize construction site areas and account for third-party infrastructure such as electricity and water lines, as per the demands of the local community [1][4].
3. Phased Completion:
4. The construction project is expected to be completed in two stages. The first phase, which encompasses the section from Hasselbrook to Rahlstedt, is currently underway. The second phase, spanning Rahlstedt to Bad Oldesloe, is anticipated to start during a five-month halt of the Lübeck-Hamburg railway line in the latter half of 2027 [4].
5. The overall completion of the S4 line is slated for the end of 2029, with the initial section to Rahlstedt operational by the end of 2027 and the complete line operational by the end of 2029 [4].
6. New Stations:
7. The S4 line will feature numerous new stations in Hamburg, including Wandsbek Rathaus, Bovestraße, Holstenhofweg, and Pulverhof. Additionally, two new stations will be built between Rahlstedt and Bad Oldesloe [4].
8. Total Cost:
9. While the specific cost of the project is not mentioned in the sources provided, it forms part of a broader infrastructure initiative that has been prioritized and financed through a financial agreement between the federal government and other involved parties [4].
