Expertise as an Alliance Partner

After successfully supporting the new Cottbus plant and the “Gäubahn North” project, the railway technology specialists have now been selected for two more alliance projects: the “Residenzbahn” and the Lübeck–Lensahn Rail Alliance. 

RSRG was awarded two new contracts in recent months within the framework of “Integrated Project Delivery” (IPA), once again demonstrating its strength as a reliable partner for collaborative success.

Just four months after winning the contract for the rail link in Lübeck, RSRG has become part of another alliance project with “Residenzbahn”. Together with long-standing partner Reif Bauunternehmung GmbH & Co. KG, RSRG is responsible for the transport infrastructure. Operating as ARGE RSRG-Reif, the two companies are in charge of civil works, cable trenching, track construction, and the construction of passenger stations.

“Residenzbahn” involves bundling several sub-projects along the Stuttgart–Karlsruhe rail corridor into a single, integrated project – from permitting through to commissioning. These sub-projects include the remodelling of track systems in Pforzheim and Wilferdingen–Singen to allow overtaking by 740-metre freight trains (part of the 740-metre network programme), the renewal of a signal box, and the reconstruction of a multi-track railway bridge in central Pforzheim. The measures also involve upgrades to the full range of railway systems – including overhead lines, signalling and control technology, lighting, 50 Hz systems, and telecommunications equipment.

Philipp Nachbaur, Managing Director of Project Business at RSRG Germany: “We are delighted that DB has once again placed its trust in us and that we can contribute to another major IPA project. We’re confident our experience in IPA collaboration will add value to the project. As a full-service provider for railway technology, we can also handle a high share of the work in-house.”

The Lübeck–Lensahn Rail Alliance – consisting of DB InfraGo, RSRG and seven other partners (12 companies in total) – is responsible for implementing the Fehmarn hinterland rail connection from Lübeck to Oldenburg. RSRG will manage the superstructure as an alliance partner in this major project, which will complete the crucial double-track, electrified link in the Scandinavian–Mediterranean corridor between Germany and Denmark.

Over the coming years, the project will involve the construction of 53 bridges and culverts, 35.5 km of noise protection walls, 110 km of track and 109 turnouts. The entire route will also be fully electrified and equipped with railway systems.

Following the joint project alliance kick-off, the planning phase, target price definition, and preparatory works are now in full swing to ensure construction begins on schedule in early 2026. Intensive and exciting challenges lie ahead for all involved, with the shared goal of commissioning the single-track section by 2029 through close, strong cooperation.

Toshe Naumov, Regional Manager North/East Germany, RSRG: “Completing the hinterland rail connection will provide the necessary capacity to sustainably and efficiently handle growing passenger and freight volumes across Europe. We’re proud to be part of this landmark project – together with Deutsche Bahn and other experienced partners.”
