[origin: WO2021186008A1] A tamping machine (14) for a works train (10) for laying, repairing or replacing a rail track (12) has a first truck (20) and a second truck (22) that are situated longitudinally at a distance from one another, a machine frame (24) and a tamping shuttle (18), the tamping shuttle (18) having a shuttle frame (38) and one or more tamping units (40) that are vertically movable with respect to the shuttle frame (38), the shuttle frame (38) being linked to the machine frame (24) by longitudinal guide means (56, 58) that allow a relative back-and-forth movement, between two end-of-travel positions, between the shuttle frame (38) and the machine frame (24) in a longitudinal direction (100) of the tamping machine (14). The machine frame (24) is entirely supported by the shuttle frame (38), which is carried by the first truck (20) and the second truck (22).
