Abstract: An anchor cribbing machine includes a pair of ballast cribbing assemblies and a pair of rail clamp assemblies. The ballast cribbing assemblies are hydraulically-driven to push ballast away from the opposing sides of a railroad tie so that an anchor may be applied to the rail at the tie location. The ballast cribbing assemblies include support beams that are movable longitudinally relative to the rails and rotatable between an operative and a stowed position. The rail clamp assemblies are configured to engage the rail to prevent the machine from being driven off the rails in operation.

Abstract: A track mounted machine is capable of inserting a previously positioned tie plate between a rail and underlying cross tie of a railway. The machine preferably is also capable of lifting the rail from the tie prior to tie plate insertion and/or, is capable of operating on both rails of a railway simultaneously. The preferred embodiment includes two tie plate inserter assemblies mounted on a common workhead. Each tie plate inserter assembly includes a pusher that can be moved, under control of an operator stationed on the machine, vertically and longitudinally on the rails so as to be aligned with a field end of the tie plate. The pusher can then be actuated to push the tie plate laterally under the rail.

Abstract: A railway grinding system is capable of grinding a frog, another switch, or another railway section of interest in situ over a precisely defined path that is unaffected by the geometry of the railway section to be ground. The system includes a frame providing the reference path and a grinding machine movable along the reference path. The grinding tool preferably has at least four degrees of freedom with respect to the reference frame. Versatility can be further enhanced by permitting one grinding tool, such as a cup grinder configured to grind a generally horizontal surface of the railway, to be replaced with another grinding tool, such as a flange grinder configured to grind a generally vertical surface of the railway. The frog grinder can perform either single-event reconditioning grinding or periodic maintenance grinding.
