A rail plate handling device is provided for removing and reinstalling rail tie plates located on rail ties on a railroad track, includes a frame configured for movement relative to the track, at least one tie plate gripping assembly mounted to the frame, the assembly configured for grasping a selected tie plate at the front and rear edges between an adjacent one of the at least one raised rail raised from the operational position supported by the selected tie plate and the associated tie in the operational position upon which the plate was resting, each gripping assembly including a pair of opposing gripping jaws which are configured for controlled reciprocation in a direction parallel to the rails along a guide bar, the guide bar being slidable with the gripping jaws and the selected plate, relative to the frame.

A singulator is provided for orienting, sorting and conveying at least one rail fastener, from a bulk supply of such fasteners, and includes a frame defining a lower end and an upper end. A plurality of transverse magnet bars is connected to an endless conveyor system disposed on the frame to move from the lower end to the upper end. A ramp is disposed on the frame, has an underside facing the magnet bars, and an opposite sorting surface opposite the underside and receiving the fasteners. At least one deflector assembly is associated with the ramp and is constructed and arranged for sorting fasteners drawn along the ramp by the magnet bars from the lower end to the upper end so that single fasteners are delivered at the upper end.

A support rail for a swing gear assembly having a thrust rail coupled to a swing gear includes a substantially horizontal first surface configured to be coupled to the swing gear such that the first surface engages a substantially horizontal top face of the swing gear, and a substantially vertical second surface intersecting the substantially horizontal first surface such that the second surface is substantially perpendicular to the first surface. The second surface is configured to engage a substantially vertical face of the thrust rail when the first surface is coupled to the swing gear. The first surface and the second surface are configured to inhibit a rotation of the thrust rail relative to the swing gear by engaging the top face of the swing gear and the vertical face of the thrust rail simultaneously.

A support rail for a swing gear includes a first flange having a first surface configured to engage a substantially horizontal top face of the swing gear, a second flange positioned opposite the first flange, and a column portion intersecting the first flange and the second flange such that the column portion is approximately perpendicular to the first and second flanges. The column portion includes a second surface configured to engage a substantially vertical inner surface of the swing gear. The first surface and the second surface are configured to substantially inhibit a rotation of the support rail relative to the swing gear by engaging the top face and the inner surface simultaneously.
