ABSTRACT OF THE DISCLOSURE The tamping machine is provided with tamping units on which each tamping tool (8) is articulated on a junction lever (26) controlled for work pivoting by a piston- cylinder unit (28) connected to a forced oscillation generator (24). The tamping tool (8) can be lifted into out-of-use position on the junction lever (26) by means of an intermediate lever (30) driven by a second hydraulic piston-cylinder unit (31), this intermediate lever being connected to said tool by a connecting link (36). In the lowered working position, the articulation (29) of the intermediate lever and the two articulations (34, 35) of the connecting link are aligned and the piston-cylinder unit (31) for the driving of the intermediate lever is abutted at the end of its stroke. As a result, the tamping tool (8) constitutes the equivalent of a rigid tool with respect to the transmission of the tamping and forced-oscillation forces.
