ABSTRACT OF THE DISCLOSURE A tamping tool assembly includes a tamping tool carrier associated with each track rail and mounted for vertical movement on a mobile track tamping machine frame. Two vibratory tamping tool supports are mounted on the carrier for pivoting about an axis extending perpendicularly to the vertical plane defined by the rail and the supports are arranged to the left and to the right of this plane. The upper ends of the supports are linked to a common drive for vibrating the supports. Two pairs of tamping tools are mounted on the lower ends of each support and the tamping tool pairs mounted on one support are spaced from the tamping tool pairs mounted on the other support so that the tamping tool pairs are in vertical alignment with a respective one of two successive cribs between three successive track ties. The tamping tools of each pair are immersible in the respective crib upon vertical downward movement of the carrier. A drive on each support reciprocates the tamping tools of each pair towards and away from the elongated tie edges defining the respective cribs.
