ABSTRACT OF THE DISCLOSURE Each tamping unit of the tamping machine has a gantry which is inclinable transversely to the track and in which the tool holder is mounted for vertical movement. The amplitude of the downward movement of the tool holder is regulated by a device controlled by a command level corresponding to the depth of tamping desired. In order to correct the differences between the depth of tamping reached and that desired which are caused by the inclination of the gantry, the said command level is lowered by a distance substantially equal to the said differences by a correction device comprising a mechanical feeler for detecting the inclination of the gantry and a mechanical connection connecting the said feeler to the sensitive member of the regulating device in order to vary the zero thereof. In a variant, this correction device is formed of an electronic circuit which permits the cancelling of the said differences.
