A tamping assembly for use in a tamping machine for compacting ballast under a group of neighboring ties of a track, includes tool carriers in spaced-apart relationship in direction of the track and vertically adjustable independently from one another, with one tool carrier including three tamping tools spaced from each other in direction of the track, and with a second tool carrier including two tamping tools spaced from each other in direction of the track wherein each of the tamping tools of the first and second tool carriers is formed with a tamping pick for immersion into the ballast. At least one of the tamping tools of the second tool carrier which neighbors the first tool carrier is adapted for movement along a first tamping direction for enabling the tamping tools of the second tool carrier to travel toward each other in direction of the axis and to tamp ballast under one tie, and along a second tamping direction for enabling the tamping tools of the second tool carrier to travel away from each other and tamp ballast under another tie in conjunction with a tamping tool of the neighboring tool carrier.
