ABSTRACT OF THE DISCLOSURE The tamping machine comprises, for each row of rails a tamping unit which is movable in the transverse direction of the track in order to tamp the track switches. The controlled transverse mobility of each tamping unit, to the right and left of the line of rails, is obtained by the combination of a lever manual control member and an automatic control circuit which is controlled by two amplitude limiters. A switch makes it possible to change from manual to automatic and vice-versa. By presetting the amplitude limiter at a value corresponding to a transverse position of the tamping unit which is repeated several times along the track switch, the positioning of the tamping unit is obtained by simple actuation of the switch upon arrival at these recurrent positions.
