The system of Profi tracks is an innovation of the Fleischmann company. The tracks, in H0 scale, with 16.5 mm of spacing of the rails, are equipped with finely rendered ballast. They are thus 3 mm higher than the traditional tracks (Model system), and specific joiners are available to connect tracks of the two systems.
