There is described a track travelling railroad switch tamping machine which has a transversally extending guide frame at its front end and four ballast tamping units one each mounted in individual sub-frames which are mounted on the guide frame. Hydraulic power means are provided to individually move each of the sub-frames with its tamping unit, transversally of the vehicle on the guide frames, independentally of each other sub-frame. Individual hydraulic power devices are provided on each sub-frame for individually raising and lowering each tamping unit within its own sub-frame, independently of the other tamping units.

There is described a self-propelled railroad track ballast broom machine having a first broom unit operatively mounted at the rear of the machine frame and a second broom unit operatively mounted at the front of the frame. The broom units have substantially cylindrical brooms extending transversely of the railroad track and deflector boxes located forwardly of each of the brooms. The brooms have gaps sufficiently wide, and so spaced apart thereon, as to avoid broom contact with the rail heads in normal tangent track sweeping operations. When the machine enters into track curves, the first broom unit is so far behind the machine rear axle that it is transversely displaced relative to the track center. Compensating transverse movement can be applied to the first broom unit to maintain the broom gaps in line with the rail heads and the ends of the broom in operative engagement with both the track shoulder edges.
