ABSTRACT:
To make a ballast-free permanent rail way, an asphalt base is applied to a substructure comprised of concrete. Railway ties, which have a recess in the center on their underside, are laid on the asphalt base. In order to secure the ties against transverse forces and to assure accurate fitting and wear-free anchoring, the ties have a first bore in the center and the substructure has a blind bore. The blind bore is filled with an adhesive and then a dowel or a threaded rod is inserted into the blind bore which passes through a sliding spacer sleeve inserted into the first bore.
