Siemensbahn
Berlin, Germany / 01.2026 - 01.2029
The Siemensbahn, a historic landmark of Berlin's transport infrastructure, is being reactivated after more than 40 years of inactivity. As part of the ‘i2030 – More Rail for Berlin and Brandenburg’ project, a modern, high-performance connection between Jungfernheide and Gartenfeld is being created. Deutsche Bahn is relying on the rail partnership model for the implementation. PORR is the contractual partner for contract package 2 ‘KIB Neubau’ (KIB new construction).

PORR realisiert wichtigen Schritt für die Berliner Mobilitätswende
As early as 1912/1913, around 24,000 people were working in Siemensstadt – one of Berlin's largest industrial sites. The Siemensbahn railway line was opened in 1929 to improve transport links for Siemens employees and local residents. After the disruptions caused by the Second World War and the boycott of the S-Bahn that began with the construction of the Berlin Wall, the line was closed in 1980 and remained unused for decades.
With i2030, the connection is being revived to meet current mobility needs. The Siemensbahn will provide the innovation and residential location of Siemensstadt Square with a direct connection to the Ringbahn – with fast connections to Berlin Central Station and Berlin Brandenburg Airport (BER). The entire project covers a distance of around 4.5 kilometres in north-west Berlin: from Westhafen via Jungfernheide through the Charlottenburg district and Siemensstadt to Gartenfeld.
‘KIB Neubau’ contract
In this important infrastructure project in the German capital, the ARGE PORR - KEMNA BAU - MCE consortium is responsible for contract package 2, ‘KIB Neubau’. It comprises the construction of all civil engineering structures, including railway bridges, stations, pedestrian tunnels, noise barriers and retaining structures in the section between Westhafen station and the ‘Unteren Spreebrücken’ at the junction with the existing elevated railway line and in the area of Gartenfeld station. In addition, the package includes earthworks and civil engineering services as well as the development and construction of logistics areas for the entire project.
Rail partnership model focuses on cooperation
The Siemensbahn project is using the rail partnership model in the eastern region.
The model focuses on integrated cooperation: planning and implementation are carried out jointly and across disciplines from the outset. This allows synergies to be exploited, quality to be assured and deadlines and costs to be reliably met. The aim is to efficiently and sustainably reconnect the line between Jungfernheide and Gartenfeld – as a contribution to modern and environmentally conscious mobility in the capital region. PORR CEO Karl-Heinz Strauss confirms:
‘We are proud to contribute our comprehensive expertise in railway construction to the implementation of this important mobility project. The rail partnership model accelerates the development of infrastructure projects and enables a particularly targeted joint approach by all parties involved.’
Challenging conditions
The work is being carried out in the inner city area, partly along existing and operational track systems. This requires precise logistics planning and the execution of numerous services within the narrow time windows provided by Deutsche Bahn. In addition, there are interventions in existing structures with heritage conservation requirements and work in the area of the Spree river. A BIM model was developed during the tendering phase in order to take the complex logistics into account at an early stage and ensure efficient implementation.
