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.

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.

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.

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.
