Abstract: A train rail track structure system includes a c-face down steel channel cross tie defining a plurality of holes in a top wider web surface thereof and a protrusion with perpendicular faces extending from an underside of the top surface, the holes configured to pass a fixative and solidifying mixture into a ballast bed there beneath. The protrusion anchors the steel channel cross tie in the fixative and solidifying mixture and the ballast bed. The disclosed system also includes a c-face down steel channel connecting link defining a receptacle for at least one intermediate rail support member in a top wider web surface thereof. The link also defines tabs and notches proximal to both longitudinal ends of the steel channel connecting link configured to interleave with at least one steel channel cross tie and interlock the steel channel connecting link to the steel channel cross tie.

Abstract: An elongate railway crosstie for supporting rail tracks on a bed of stones or the like, said tie having a first end, a second end, a length between said first and second ends and a top surface, a bottom surface and a pair of side surfaces between said first and second ends, characterized in that at least one of said side surfaces has a portion of a non-planar stone-embeddable form extending between said first and second ends, so-shaped as to effect reduced lateral and longitudinal slippage of said tie within said bed, while providing a reduction in the volume of material used.

Abstract: The invention relates to a sleeper (1) for a gravel-mounted structure in railways, which has a cross member (4) extending along a sleeper longitudinal axis (6) and two longitudinal members (5) spaced apart from one another by the cross member (4), and each longitudinal member (5) has a bearing (9) extending on a top face for mounting a rail element (10) above the longitudinal member (5). Each longitudinal member (5) has one or more mounting devices (26) for a rail fixing element (28) each for retaining a rail element (10) on the longitudinal member (5) and at least one of the mounting devices (6) is disposed transversely offset from the sleeper longitudinal axis (6) on at least one of the two longitudinal members (5). The invention further relates to a sleeper (1) of this type which is of a stepped or recessed design at the ends of the longitudinal members (5) , to enable connecting elements (56) to be fitted in these regions in order to secure two rail elements (10) lying end to end.

Abstract: To increase the resistance of plastic and/or plastic composite railroad ties tosliding within the ballast of the railroad bed, for example, sliding lengthwise (in the direction of the longitudinal axis of the tie) and sideways (in the direction perpendicular to the longitudinal axis), ties with a textured surface which aids in anchoring the ties within the ballast of the railroad beds. In particular, the ties are provided with a pattern of indentations within a surface that contacts the ballast which increases the ties resistance to sliding. The pattern is molded into the ties so as to mechanically interact with the ballast (rocks) and provide as much resistance to sliding as possible, especially along the longitudinal axis of the tie but also in the direction perpendicular to the longitudinal axis.

Abstract: A method for installing a steady rail track, for which the concrete railroad ties, which carry the rails or auxiliary rails and the continuous reinforcement of which protrudes below out of the only partially constructed concrete casing, are preinstalled initially into a rail grid and subsequently lined up positionally over a supporting layer and embedded in a casting composition, the rail grid, with interposing of a supporting reinforcement, which is optionally tied to the underside of the railroad tie reinforcement, being aligned directly over a hydraulically bound supporting layer and the casting composition, preferably using movable, removable side formwork, is applied on the hydraulically bound supporting layer.

Abstract: A road transportable concrete railroad long-line tie molding system is described in which a rigid horizontal metal stressing frame is assembled from transportable sub-frame segments. The sub-frame segments are releasably connected in axially aligned end-to-end relation, and include parallel longitudinal reaction members. In a preferred form, the sub-frame segments are convertible from inoperative transport conditions to extended operative conditions. Footings are provided along the stressing frame length to engage the sub-frame segments to releasably mount the sub-frame segments in axial alignment and stabilize the reaction members against lateral deflection during compressive loading. A plurality of conventional gang tie molds having upwardly open elongated mold cavities are releasably received in end-to-end alignment along the framework. A reinforcing wire anchor is provided on the sub-frame at the dead end of the framework and a tensioner is located at the live end of the framework.

Abstract: A pair of mud dispersement devices are deployed beneath a railroad tie and upon ballast material supporting the tie. Each device includes a flat elongated structure for underlying a half of the railroad tie and resting upon the ballast material supporting the tie. The elongated structure has opposite inner and outer ends and opposite top and bottom surfaces and defines a wedge-shaped cavity below the bottom surface which increases in height proceeding from the inner end of the elongated structure to the outer end thereof. A plurality of support elements are mounted on the top surface of the elongated structure and project upwardly therefrom for contacting the railroad tie to transmit a load produced by rolling stock moving on the railroad track downwardly from the railroad tie to the inclined plate.

Abstract: A rail tie has a pair of rail supporting portions disposed on opposite sides of a central portion. The central portion is elevated relative to the central portion and supports a reaction rail of a linear induction motor used to propel a vehicle along the guideway. The reaction rail is secured to flanges extending laterally from the central portion to reduce the unsupported span of the reaction rail between ties. The tie is supported on the deck of the guideway by resilient pads. An eccentric insert cooperates with a securing stud to allow alignment of the tie.

Abstract: An arrangement at crossings between a road and a railway. Between the rails and the respective edges of the road structure and between the rails are arranged first and second slabs level at their top surfaces with the top surfaces of the rails and the top surfaces of the road structure. Elongated supporting elements rest on the foundation and are located at the edges of the first slabs which face the road structure. On the supporting element a first edge to which the road structure adjoins with a second edge opposite to the first edge of the supporting element, forming a support for the edges of the first slabs, and a support for the opposite edges of the slabs facing the rail is provided on the end portions of the sleepers outside the rails.

Abstract: Apparatus for molding rail ties of the type which include one or more fastening devices embedded in the concrete of the type having a shoe plate which rests on the tie and a projecting tab part, the mold having plates, which are preferably removable inserts, for accepting the shoe portion of the device, and flexible jaws which engage the projecting tab part to align it with respect to the mold.
