A rail ballast management and tie guide ski is provided for use with a rail tie exchanger machine moving along a railroad track. The assembly includes a workhead frame configured for attachment to the tie exchanger, the workhead frame having a vertically oriented sleeve defining a cavity, a tie ski having a generally planar tie engaging surface, an opposite upper surface, a connection point at each of two free ends, and a mounting lug is dimensioned for slidably engaging the cavity, and is pivotally connected to the tie ski. Also connected to said tie guide ski assembly is a pair of fluid power cylinder assemblies, one said cylinder assembly connected to a respective connection point at a first end, and to the sleeve at an opposite second end, such that selective pressurization of said fluid power cylinder assemblies causes reciprocal movement of said tie ski relative to said sleeve.

A plate retainer apparatus is provided for use on a railroad track with a tie exchanger having a main frame, the apparatus configured for gripping and retaining rail tie plates to a rail during a rail tie exchange process. The plate retainer apparatus includes a plate retainer workhead constructed and arranged for movement independent of that of the main frame. Included on the workhead is a pair of workhead modules, each module associated with a rail of the track and configured for retaining a single tie plate associated with a target tie at a time. Each workhead module is movable relative to the main frame independently of each other.
