The first prefabricated double-track tram turnout

We have completed production of the world's first prefabricated double-track tram turnout. This solution is part of a larger infrastructure project underway in Poznań, which will create a comprehensive tram hub, the so-called "full star," constructed using Krakow-based prefabrication technology.

Scale of the project

The project will involve the construction of 123 precast panels, with a total area of ​​2,365 m² —the size of almost two Olympic-sized swimming pools. Approximately 850 m³ of concrete was used to produce them . This technology allowed the most arduous phase of the work to be moved outside the city limits. This reduced the need for concrete mixer transport to the construction site, minimizing the impact on traffic and city operations.

The average surface area of ​​a single slab is approximately 19 m², significantly exceeding the standards of previous projects. The largest elements reach 26.4 m² – these are two slabs planned for installation in the first phase of the work.

Individual customization and quality workmanship

The prefabricated elements – as always – were designed and manufactured for a specific order , taking into full account the geometry of the track system, the height system, and the operating conditions at the site of construction.

At the investor’s request, the upper texture of the panels was made in a new brushed pattern, which confirms the flexibility of prefabrication technology in terms of functional and aesthetic solutions.

Advantages of prefabricated technology

The technology used is characterized by high initial quality of components, repeatable parameters, and a significant reduction in construction time. Another significant advantage of prefabrication is the ability to conduct assembly in winter and in difficult weather conditions, which would entail a high risk of downtime and delays with traditional technologies.

Prefabrication ensures:

• technological continuity,
• durability of the structure,
• schedule optimization,
• reduction of costs throughout the entire life cycle of the facility (LCC).

The importance of the project

The completion of the first prefabricated double-track tram turnout is further proof that a change in approach to planning the renovation and construction of key tram tracks is possible even in the most complex cases, and that technological development still holds potential. This represents a new chapter in the design and implementation capabilities of future infrastructure investments in rail transport.
