WEGH Group manufactures a ballastless system consisting of prestressed reinforced concrete prefab slab tracks (Arianna Slab System) that are laid on a base foundation. WEGH was the first company to design this slab track system in Europe back in 1987 and, ever since, our slab tracks have been used successfully in important railway lines (international line Pontebbana, HS line Roma-Firenze, etc.). This system features slab tracks that are specifically designed for railway, tramway and underground lines.
