Abstract
Structural system comprising a track for a magnetic levitation transport system powered by a linear electric motor. This structural system comprising a track for a magnetic levitation transport system powered by a linear electric motor is notable in that it combines two T-shaped tracks produced in a single U-shaped structure, the vertical bars of the T-shapes and the U-shapes being joined, and the lower slabs of the track-supporting U-shapes contributing to the general strength of the engineering structure, in the absence of lateral screens.
