Railway construction
Expertise on the rails.
Thanks to its international expertise, PORR is involved in numerous rail network projects.
With the PORR Group’s acquisition of a majority stake in Knape Bahnbau GmbH, based in Dorfen (Upper Bavaria), the company’s long-standing expertise in railway construction – particularly in the German market – has been consolidated. The company specialises in railway construction in Germany and specifically expands PORR’s range of services in the field of rail infrastructure.
Knape Bahnbau works closely with other units of the PORR Group, leveraging synergies, modern technology and extensive experience from infrastructure and major projects. This enables complex railway construction projects – from planning and construction to the maintenance of track and points systems as well as railway traffic facilities – to be carried out efficiently and from a single source.
Our services include the new construction, maintenance and refurbishment of track and points systems as well as railway traffic facilities. In addition, we deliver turnkey railway lines. As experienced specialists, we undertake all work relating to track systems – from traditional track construction and railway-specific civil engineering to underground cable works, including cable laying and the installation of fibre-optic cables (FOC).
Our pre-qualification with Deutsche Bahn, state-of-the-art technical equipment and qualified specialists ensure the optimal preparation and execution of your construction project.
PORR’s innovative strength is impressively demonstrated in the development of the Slab Track Austria slab track system, which was implemented in collaboration with ÖBB. This state-of-the-art, modular system sets new standards in the field of high-speed transport and underlines PORR’s commitment to creating forward-looking solutions for rail infrastructure.

Areas of expertise in railway construction.
Railway construction.
Our key areas of expertise in railway construction include the construction and modernisation of track and points systems – both on the Deutsche Bahn AG network and for industrial sidings.
We offer comprehensive services in the field of track-side civil engineering, including the installation of a wide variety of drainage systems, right through to deep drainage. Our areas of expertise include professional cable installation, the installation of ballast retainers as well as the rehabilitation of sub-bases.
Furthermore, we are on hand to provide you with sound technical advice for your railway project.
Underground cable installation.
In addition to railway construction, our comprehensive range of services in the field of underground cable installation ensures a reliable and high-performance rail network. You can rely on our expertise for sustainable railway infrastructure and seamless data management along the rail network.
We carry out the construction of new drainage systems – from standard solutions to complex deep drainage – and install all types of modern cable routing systems.
With professional installation of driven-pipe foundations, the expert fitting of signals, as well as the precise pulling and laying of a wide variety of cables, we safeguard the infrastructure of your railway line.
Furthermore, we undertake the installation, splicing and termination of fibre-optic cables and ensure maximum operational reliability through careful testing and documentation of your fibre-optic systems.
Maintenance.
A track infrastructure that remains efficient and available in the long term requires regular maintenance. Our experienced specialists ensure the long-term preservation of the value of your track systems – regardless of whether you prefer a comprehensive maintenance contract or flexible individual contracts.
We take care of the maintenance and upkeep of your railway line, thereby ensuring maximum reliability. Our services include the professional maintenance of tracks and points, comprehensive documentation, as well as specialist inspections of track and points systems – ensuring your railway infrastructure always functions optimally.
Using state-of-the-art measurement technology, we carry out precise inspections, identify potential weak points at an early stage and document all results comprehensively. Furthermore, we are available to you as a competent point of contact for all matters relating to railway authorities.
Slab Track Austria.
Slab Track Austria’s slab track represents a modern and future-proof technology in track construction. The modular and flexibly adaptable system impresses with maximum track accuracy whilst requiring minimal maintenance. Thanks to industrial prefabrication under controlled factory conditions, installation is particularly efficient – only a few steps are required on site.
The slab track is based on a ballastless superstructure, the central element of which is the elastically mounted track support slab made of loosely reinforced concrete with integrated rail supports. Elastic separation layers at the base of the slab and in the conical grouting openings ensure structural decoupling and effectively reduce vibration and structure-borne noise. Installation takes place on a low-settlement substructure consisting of a concrete base course and a hydraulically bound base course, both of which are approved in accordance with the requirements of the German Federal Railway Authority (EBA). Following precise fine-alignment, the track support slab is grouted with self-compacting concrete, which further enhances the system’s durability and operational reliability.
With Slab Track Austria, you are choosing a sustainable solution that guarantees a permanently stable and precise railway infrastructure – ideal for demanding construction projects in modern rail transport.
Machinery and logistics.
To ensure the successful delivery of railway construction and track-side civil engineering projects, we rely on our own fleet of modern, high-performance machinery and equipment. This advanced machinery and equipment guarantees the efficient, precise and timely completion of our railway construction and cable civil engineering projects.
Our state-of-the-art dual-mode technology enables flexible deployment at various locations along the railway line.
Using D3 crawler machines equipped with innovative 3D control systems, we ensure the rapid and precise installation of protective layers and ballast beds.
For cable trenching as well as the construction of drainage and verging systems, we have soil cutters with transfer trailers at our disposal.
Our equipment is complemented by versatile specialist transport vehicles.
Certificates/Approvals.
Compliance with defined quality requirements is an essential part of project management at PORR. This is also evidenced by our certificates and accreditations. These are regularly reviewed and renewed through external audits and by independent certification bodies.
One-stop solutions.Safe and cost-effective.
PORR has many years’ experience in the planning and execution of complex construction projects – from the initial concept development right through to handover as a turnkey project.
Drawing on our extensive expertise, we deliver bespoke solutions. Across the entire construction value chain, we have our own teams of experts in all key trades and offer comprehensive specialist knowledge from a single source: in data centres, railway construction, government services, building construction, industrial construction, civil engineering, mineral resources, specialised civil engineering, tunnelling, environmental technology and transport infrastructure construction.
Our service portfolio ranges from general planning to the final implementation.
Our expertise – your benefits:
Holistic planning and execution
