Abstract: 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.

Abstract: A dual wheel adapter assembly for mounting dual wheel rims to a wheel hub is provided. The dual wheel adapter assembly may include a hollow cylindrical adapter, including a central bore defined by an inner surface of the adapter, a first contact surface, and a second contact surface. The dual wheel adapter assembly may also include an inboard wheel rim configured to support a tire, an outboard wheel rim configured to support a tire, and a wedge clamp configured to be coupled to the hub. The first contact surface may abut the hub and the wedge clamp may apply a compressive force to the second contact surface to couple the adapter to the hub.

Abstract: The present disclosure is directed to a diaphragm air seal providing a seal between a cylindrical housing, such as an axle box, and a cylindrical body, such as a traction motor, disposed within the cylindrical housing. The diaphragm air seal may include a first flange having a first sealing surface sealingly engaging the cylindrical housing, a second flange having a second sealing surface sealingly engaging the traction motor, and an air seal body extending between the flanges. The air seal body may be formed from an elastomeric material and have an S-shaped transverse cross-section. An assembly may include the diaphragm air seal and may further include an air seal weldment having a radial weldment flange and an axial weldment flange extending axially outwardly from the radial weldment flange so that the first flange of the diaphragm air seal may be disposed on and sealingly engaging the radial weldment flange.
