Urban rail transport is the backbone of modern, liveable cities. It creates efficient, environmentally friendly connections and relieves pressure on urban areas. Constructing this infrastructure while the city continues to operate places the highest demands on precision, logistics and the coordination of a wide variety of trades.

Our group of companies has a leading expert for this demanding niche: Kallinger Bau GmbH. As a specialist in urban railway construction, it combines decades of experience and is the ideal complement to SWIETELSKY's railway construction division. Projects are also carried out in close cooperation with specialists from SWIETELSKY.

• Comprehensive track construction: We construct and renovate urban track systems of various gauges and superstructure types.
• Integrated civil engineering work: We take on all work related to the track, from substructure and drainage to pipe construction and final surface design with asphalt, paving or concrete.
• Specialised machinery: With track-mounted construction machinery such as road-rail excavators and dumpers, as well as special attachments, we work efficiently and safely even in the most confined inner-city spaces.
• Maintenance and renovation: We carry out all maintenance work, from replacing individual components to machine processing of entire sections of track.

• Slab track for heavily loaded lines and tunnels
• Ballasted tracks as a classic and economical option
• Green or grass tracks to reduce noise and create an attractive appearance
• Complex switch and crossing systems
• Special designs such as indoor or measuring tracks for industry and transport companies

Whether for municipal transport companies or industrial clients, SWIETELSKY offers reliable and comprehensive project management in urban railway construction through its specialist Kallinger. This is how we shape urban, environmentally friendly mobility.
