Abstract
A railway track working machine is provided with a vibratory ballast surface compactor. The compactor has a top ballast engaging plate and a second ballast engaging plate arranged to work in association with top ballast plate (hinged or otherwise) along an outer longitudinal edge of the top plate. The top plate has a leading edge and a trailing edge and a ballast compacting under-surface, the leading edge being wider in a direction tranversely of the track than the trailing edge and the compactor is mounted so as to present, in ballast compacting operation, the top plate leading edge at a higher level above the ballast surface than the trailing edge, the under-surface of the top plate sloping rearwardly in the direction of track working from the leading edge to the trailing edge. The trailing edge is adjusted, in operation, so as to be located at a selected level for ballast compaction.
