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.

Abstract: A prestressed concrete railroad tie having a tie body made up of two end members for supporting rail attachment parts and a central section extending between and interconnecting the end members and having a transverse cross-section smaller than the transverse section of the end members. Tendons are located in the tie body and extend in opposite directions from a common vertical or horizontal plane in the central section into the end members. At tie ends of the end members the tendons are anchored and are uniformly distributed across the transverse cross-section of the end members. With the tendons centered in the central member, a narrow central member is afforded. The tendons fan outwardly from the common plane in the central section into the end members providing wider or larger end members. This prestressed concrete tie arrangement affords only low changing bending moments in the central section or a positive course of bending moments across the length of the tie.

Abstract: A railroad railway for rail-mounted vehicles capable of high speed travel includes a track grating formed of rails and ties with the ties partially embedded in a poured-in-place steel reinforced concrete slab. The concrete slab is mounted on a continuous concrete substructure with a separating layer arranged between the slab and substructure. A single layer of steel reinforcement is located in the concrete slab spaced below the ties. The slab is dimensioned so that it serves only for plate-like stiffening of the track grating without any appreciable inherent bending resistance. The slab is secured against longitudinal and transverse displacement of the substructure, while the substructure is dimensioned to absorb bending moments developed in the longitudinal direction of the rails. The concrete slab is divided in the longitudinal direction by transversely extending expansion joints whereby sections of the slab can be replaced if damage occurs.
