The results of the testing by TUV SW Standardization Certifications has proven that the innovative uSky track structure is safe and not inferior in safety to standard passenger transport technologies.


Some of the inspection conducted under the verification procedure were:

  • Visual and dimensional verification of track structure,

  • Torque tightening inspection of track structure,

  • Deflection of track structure.

The basis of the string-rail track structure is uRail. The uRail is a conventional continuous (along the length) steel, reinforced concrete or composite steel reinforced concrete beam or truss equipped with a rail head and additionally strengthened with pre-stressed (tensioned) strings.


The uRail combines the characteristics of the flexible cable (at a long distance between anchored supports) and rigid beam (at a small beam span – under a wheel of a uPod and above the support).


Also, at the heart of the integrated technology, there are several types of uRails, each with individual technical features and consumer qualities. The selection of a string rail type depends on the track design and function as well as the goals set, whether it will serve for passenger or freight traffic, whether it shall accommodate eventual expansion of the line or shifting a rolling stock from passenger to freight type and vice versa.
