Abstract
A reversible track section for a toy car circuit. The reversible track section has a length, two opposite ends, two opposite sides, a top surface and a bottom surface. The reversible track section includes a thin, elongated plate including a central recess on the top surface. The central recess is of given height and rectangular cross-section and extends over the length defining two narrow pathways on the bottom surface, and includes a pair of longitudinal flanges on each of the opposite sides extending perpendicular to the top surface and towards the bottom surface. The longitudinal flanges are of the same height as the central recess and each is provided with an integral, outwardly projecting extension of constant width. The extension has a top surface, a bottom surface, a lateral surface, a thickness smaller than the height of the corresponding longitudinal flange, including a central portion and opposite ends thicker than the central portion, provided with alternating studs and cavities along the length on both the extension top and bottom surfaces and with an outwardly projecting stud extending perpendicularly to the lateral surface on each of the end portions. In a pit, a plu…
