Abstract
The invention relates to a form for producing concrete rails for rubber-tired vehicles which are guided on a track. In contrast to steel rails, concrete rails no longer bend after production, so that numerous different molds are required for curves, transition curves, super elevations, and the like. This drawback is avoided with the form according to the invention, wherein the form makes it possible to produce both straight rail sections, as well as rail sections having varying curvatures, using the same mold. As a result, the expenditure for rail forms is considerably reduced.
