The disclosed solution generally relates to a switch point roller assembly. The switch point roller assembly is configured to be operatively connected to a switch point within a railway switch. The switch point roller assembly comprises a spring, a bolt assembly, a roller assembly, a housing assembly, and a base plate. The base plate may be secured such that the roller assembly is in substantial contact with a railway plate during movement of the switch point—such that the operation of the switch point is improved. As such, the switch point is more resilient to wear thus leading to decreased maintenance costs and increased safety for personnel, passengers, and property.
A solution is disclosed comprising a moveable point frog friction-reducing assembly configured for installation at or near a moveable point frog (also referred to as a swing nose crossing). In one aspect, the moveable point frog friction-reducing assembly is configured to use a plurality of roller assemblies to reduce friction. In another aspect, the moveable point frog friction-reducing assembly is configured to use a sliding block to reduce friction. Some of the many benefits of the disclosed solution are to increase the operational life of a moveable point frog, reduce the maintenance costs of a moveable point frog, and to protect property, and more importantly human lives.

A tie having a non-linear keyway under the overlying rail to provide support to restrain lateral and longitudinal movement of the rail. A fastening system to hold rails down on a tie comprises a rail plate that may be fastened to the tie within the keyway. The fasteners are protected to avoid damage in case of a derailment or other adverse conditions. Also disclosed are visual inspection mechanisms to assist with determining whether a fastening system is securely attached to the tie.

A boltless brace assembly for a rail includes a base block interlocked with a brace, and further includes a wedge to be inserted between an upper surface of the base block and a lower surface of the brace, thereby applying an upward force to the brace and a resultant downward force to secure the rail base. The brace assembly may be modified to provide a universal brace assembly, a resilient brace assembly, or a frog base clamp.

An elongated rail fastener apparatus for use near an obstacle such as a guard rail, or other location where space is restricted. The fastener preferably extends past the obstacle and is provided with a shoulder having at least one elevated notch, positioned to allow installation of the clip with a vertical and lateral movement, and without the application of a large force perpendicular to the rail. A U-shaped embodiment of the fastener is also described.
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.
A controller for a spring wing on a frog that utilizes a floating piston rod carrying a fixed piston valve and a free-moving piston head is provided. When the piston rod is actuated by the opening movement of the spring wing, the piston valve separates from the piston head briefly, allowing oil to flow through the piston head in a relatively unrestricted manner. The piston head is spring biased towards the piston valve; upon contact between the piston head and the piston valve, the oil flow through the piston head stops, helping to hold the spring wing in the open position. When the spring wing begins to close, the adjustable oil flow through the controller allows the piston rod to move at a controlled rate, thereby controlling the closure rate of the spring wing.
A hydraulically powered switch machine having power and manual operating modes, and a dual disconnect mechanism. In power operation mode, the machine may be operated remotely, or using controls located on or near the machine. In the event of power failure, the machine may be operated manually. The dual disconnect mechanism physically disconnects the powered throw mechanism when the machine is operating in manual mode and physically disconnects the manual throw mechanism when the machine is operating in power mode, in both cases preventing unexpected movement of the manual throw mechanism.
The invention relates to an interface pad comprising a stiffener supporting a resilient pad to cushion the panels in a grade crossing between and around the rails from impact with the underlying ties and to prevent the panels from moving. 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 to securely fasten such an interface pad to a railroad tie and minimize the possibility that the interface pad will be forcibly removed from the tie during installation of the rails or panels in the grade crossing.
The invention is an apparatus for pre-plating railway ties, including switch ties of varying lengths. An infeed deck and singulator feeds individual ties, each provided with identifying indicia, to a pre-scanner. Using the scanned indicia, a control system accesses stored data to determine a preliminary drill pattern. A scanning and drilling station positions, secures and scans the tie. The scan results are combined with the stored data to produce a corrected optimal drill pattern, which is used to drill the tie. The drilled tie moves to a plate and screw loading station, where the proper plates and fasteners are attached. A fourth station inspects the assembled tie. If it is properly assembled, the screw spikes are tightened and the plated tie moves to an outfeed deck, where it is marked for identification and removed for storage and shipping.
An insulated rail joint assembly comprises a rail with a thick web section, held in place by joint bars and secured with electrically isolated fasteners. The joint bars have non-uniform cross-sections, being shaped with a thicker midsection area and thinner ends. Electrically non-conductive shear pins through the rail and the joint bars provide shear resistance and prevent glue bond failure. High strength cloth between the rail ends and between the rail and the joint bars strengthens the joint, as does an insulating rail clip resiliently fastened to an insulating tie plate, which itself may be supported on a cross tie of increased width.
