  • Tamping device and method of tamping a railroad track's ballast
    Patent number: 6978718
    Abstract: A tamping device and method of compacting ballast beneath the intersection of a railroad track's tie and rail utilize a pair of tamping units, each of which terminates in a tool blade. When a pair of tamping unit's first and second tool blades are in ballast on either side of the track's tie along one side of the rail, the first and second tool blades are moved in respective counter rotational first and second orbital paths such that forces generated in the ballast by the blades cooperate to compact the ballast beneath the intersection of the tie and the rail.
