  • Publication number: 20140312133
    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.

  • Publication number: 20080099571
    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.

  • Patent number: 7011253
    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.

  • Patent number: 6237856
    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.

  • Patent number: 6059199
    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.

  • Patent number: 5540382
    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.

  • Patent number: 5314115
    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.
