Comprehensive Delivery of Rail Track Systems
The consistent expansion of competencies in the rail infrastructure segment led to the establishment of the KZN Bieżanów Group — a capital group jointly building a comprehensive offering for rail track investment projects, maintenance, and modernization. Today, it consists of nine independent yet closely cooperating companies, including one based in Germany and one operating as a Polish-Spanish joint venture.
The KZN Bieżanów Group is a key supplier of specialized products and services related to modern railway and tram infrastructure. Its advanced technical facilities and team of experts enable the development of new technologies for modern, cost-efficient, and environmentally friendly transport.

We are committed to sustainable development, maintaining a balance between the growth of railway infrastructure and environmental protection. We implement innovative solutions that reduce CO₂ emissions, promote a circular economy, and minimize the impact of our operations on ecosystems. We also support local communities through cooperation with non-governmental organizations.
