The tamping tool assembly includes three pairs of vibratory tamping tools spaced from each other in the direction of track elongation so that the pairs of tools may be immersed in three successive cribs. The tools of each pair are reciprocable in opposite directions towards and away from the elongated edges of adjacent ties wherebetween the cribs are defined. All tamping tools are vibrated by a common drive and drives are provided for reciprocating the tamping tools.
