摘要:
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.
摘要:
A system for fastening a rail to a solid foundation, and a method for renovating a rail-fastening point. The system and the method allow a fastening point for a rail to be easily and economically renovated in such a way that a permanently reliable function of the renovated fastening is then ensured again while the worn support section remains. The system for fastening a rail to a solid ground foundation includes: a layer formed by a compensating mass applied to the support section; a base plate resting on the layer and extending over the support section, upon which the rail is supported in the finally installed state; a spring element for exerting a resilient elastic retention force on the rail; and a clamping element that can be anchored in the solid foundation for clamping the spring element.

A cleated belt conveyor is positioned atop a frame connected to a hi-rail truck. The cleated belt conveyor is operably connected to a railroad engagement wheel positioned under the frame to coordinate movement of the cleated belt conveyor relative to the railroad engagement wheel. A sliding member can be positioned at the top, or infeed end, of the cleated belt conveyor for receiving railroad tie plates from an infeed conveyor. One or more sets of rollers can be positioned at the bottom of the cleated belt conveyor for distributing the tie plates near a rail in a desired orientation.

First and second conveyors are positioned along opposite sides of a frame positioned about centrally between the first and second conveyors, wherein the first and second conveyors are operably connected to a railroad engagement wheel positioned under the frame to coordinate movement of the first and second conveyors relative to the railroad engagement wheel. The conveyors can be integrated with a hi-rail truck adapted for use with the first and second conveyors and which contains an infeed conveyor for transporting tie plates from the hi-rail truck to the first and second conveyors.
摘要:
A system (10) for sensing a condition of a rail vehicle undercarriage component (e.g., 18) includes a sensor (e.g., 12) comprising an array of infrared sensing elements (29). Each of the elements may be aimed at a different region of a target area (e.g., 32) of a rail vehicle undercarriage component to generate respective scanning waveform signature data corresponding to each different region. The sensor may be oriented so that at least one of the elements receives unobstructed infrared emissions (e.g., 33) from the undercarriage component of a rail vehicle passing the sensor. The system also includes a memory (42) for storing characteristic waveform signature data corresponding to known undercarriage components. In addition, the system includes a processor (40) for processing the scanning waveform signature data with respect to the characteristic waveform signature data stored in memory to identify a type of the rail vehicle undercarriage component being scanned and to extract information indicative of a health condition of the rail vehicle undercarriage component being identified.

In the case of a hollow sleeper (1) for adjusting devices of switch blades of railway points, movable common crossings or cable crossings in any desired sections of track and points, formed as an upwardly open hollow sleeper profile with a planar sleeper underside (2), for fitting in a track skeleton, wherein the cross-sectional width and height are made to match a normal concrete, wooden or steel sleeper, the positional stability on ballast can be improved if the sleeper underside (2) of the hollow sleeper (1) is formed with at least one sunken, downwardly open chamber (5).
摘要:
A railway vehicle for inserting plates on rail ties that engage with rails includes a frame configured for movement relative to the track and a plate inserter workhead mounted to the frame. The plate inserter workhead is configured for pivoting the tie plate about a leading edge of the plate so that the trailing edge of the tie plate is lifted off the tie. The plate inserter workhead is configured to subsequently release the plate.
摘要:
This invention provides a method for restoring at least one means defining a railroad spike hole located in a used railroad tie. In this way, the restored railroad tie can be reused in subsequent rail replacement operations. The restored railroad tie is capable of having a railroad spike penetrate and be retained within the confines of the restored railroad spike hole without substantial bending problems. The used railroad tie provided has at least one spike hole located therein. In each the means defining a railroad spike hole is formed a polymeric plug. The polymeric plug comprises a polymeric plug formed of a polymeric material including a plurality of flexible, readily deformable micro-inclusions which allow the formation of spike insertion pathways that track the insertion forces of the railroad spike as it is driven into a material thereby facilitating introduction of the railroad spike into said polymeric plug. The polymeric plug is capable of penetration by and retention of the railroad spike there within.

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.
