Pad for a railway rail fastening assembly
A pad for a railway rail fastening assembly, the pad being configured for placement between a rail and an underlying foundation, such as slab track or a sleeper, wherein a cross-section of the pad comprises: a second resilient layer configured to face a railway rail; an intermediate rigid layer; and a first resilient layer configured to face an underlying foundation. The rigid layer is provided between and is integrally formed with the first and second resilient layers. An edge of the pad comprises at least one ear that extends beyond a central region of the pad, the rigid layer extending into the ear with the ear being configured to resist rail roll.
Rail fastening system
Rail fastening system for fastening at least one rail (2) to a rail substrate, preferably a solid travel path, which comprises: a rail support plate (1) arranged for holding the rail (2), wherein the rail (2) in the mounted state is in contact with the rail support plate and is fastened thereto by a rail mount (1a, 1b, 1c); a base plate (3) arranged for fastening the rail support plate (1) on the rail substrate, wherein the rail support plate (1) in the mounted state is fastened on the base plate (3) by way of one or more, preferably two, retaining elements (6) and the base plate (3) is in contact with the rail substrate; wherein the base plate (3) is of multi-part, preferably two-part, construction so that this is adjustable to different dimensions of the rail support plate (1).
Track rail fastener and system for pedestal mounted track rail
A fastening system for track rail includes a track rail fastener positionable upon a pedestal mount, and including a top plate, a frame, and an overmolded jacket. The system further includes a lateral positioner having an eccentric structured to contact a pedestal mount, and a locating pin extending through the fastener body and the eccentric to couple a lateral location of the fastener body to an angular orientation of the eccentric, such that rotating the eccentric varies a lateral location of the fastener body. A frame in the fastener body includes a plurality of vertically extending finger walls for lateral and rotational stability, with the overmolded jacket extending between the finger walls and the top plate.

Rail Fastening System
Rail fastening system for fastening at least one rail (2) to a rail substrate, preferably a solid travel path, which comprises: a rail support plate (1) arranged for holding the rail (2), wherein the rail (2) in the mounted state is in contact with the rail support plate and is fastened thereto by a rail mount (1a, 1b, 1c); a base plate (3) arranged for fastening the rail support plate (1) on the rail substrate, wherein the rail support plate (1) in the mounted state is fastened on the base plate (3) by way of one or more, preferably two, retaining elements (6) and the base plate (3) is in contact with the rail substrate; wherein the base plate (3) is of multi-part, preferably two-part, construction so that this is adjustable to different dimensions of the rail support plate (1).
Method of installing interface pad on concrete ties
An interface pad for a concrete tie includes a resilient contact pad to cushion the tie from any overlying parts in a railway application, such as panels in a grade crossing or rails in a turnout. The pad may be flat or a cupped shape and may be of varying size to accommodate varying tie widths. The invention further comprises means and methods to correctly secure such an interface pad to a concrete railroad tie and minimize the possibility that the interface pad will be forcibly removed from the tie during installation of the tie.
Recessed concrete rail seat assembly
A low maintenance rail seat has recess in the concrete tie and an abrasion plate that covers the floor of the recess and its sides parallel to the rail base. The abrasion plate includes ribs which seat in additional recesses in the tie to retard longitudinal movement. The anti-abrasion assembly preferably has four flanges which wrap around the top of concrete tie to prevent dust particles from entering and abrading the concrete rail seat. These flanges also wrap around the support shoulder for additional resistance to longitudinal movement. The components are designed to provide 8.5 of lateral support along the side of the rail base while the traditional e clip fastener provides only 3 of lateral support. The interlock feature between the anti-abrasion assembly and the concrete tie also minimizes relative movement between abrasion plate and concrete tie, which results in less concrete surface abrasion.
A PAD FOR A REAILWAY RAIL FASTENING ASSEMBLY
A pad for a railway rail fastening assembly, the pad being configured for placement between a rail and an underlying foundation, such as slab track or a sleeper, wherein a cross-section of the pad comprises: a second resilient layer configured to face a railway rail; an intermediate rigid layer; and a first resilient layer configured to face an underlying foundation. The rigid layer is provided between and is integrally formed with the first and second resilient layers. An edge of the pad comprises at least one ear that extends beyond a central region of the pad, the rigid layer extending into the ear with the ear being configured to resist rail roll.
Rail fastening arrangement and shim for such a rail fastening arrangement
A rail fastening arrangement in which a rail for a rail vehicle is fastened to a base, and to a shim. The rail fastening arrangement includes two guide plates, of which one guide plate respectively is associated with one of the longitudinal sides of the rail, and a shim which is arranged between the base and the rail. The shim, at its top, has a contact area on which the rail is supported, and, at its bottom, has a supporting surface by way of which the shim is supported on the base. The contact area and the supporting surface of the shim, viewed in a section located transversely to the longitudinal extension of the rail, enclose an acute angle. The edge at which the shim is thinner is arranged beneath the rail, fastening of rails oriented at a cant relative to the vertical in the region of points.
Rail gauge-plate insulator
A gauge-plate insulator for positioning between and mounting to two rail-spacing members that in turn extend transversely between and mount to two parallel rails to mechanically interconnect but electrical insulate the rail-spacing members and thus the parallel rails. The insulator includes a plate, front and rear mounting holes extending vertically through the plate, and a tongue extending downward from the plate along its lateral midsection from front to back. In typical embodiments, the insulator includes elongated platforms surrounding the mounting holes and arranged perpendicular to the tongue, and the insulator is of a one-piece monolithic construction made of a material selected for mechanical strength and electric insulation. And in some embodiments the insulator includes a tented top surface, ribs extending perpendicular to the tongue, and/or multi-level platforms.
