A compaction and ballast removal machine for railway tracks comprises a railway car (2) movable along an advancing direction (A), a compaction unit (9) and a ballast removing unit (12) associated with the car (2) and slidably movable, both relative to each other and relative to the car (2), along the advancing direction (A). The machine (1) further comprises actuating means (16) operatively acting between the compaction unit (9) and the ballast removing unit (12) for determining a mutual positioning of the compaction (9) and ballast removing (12) units, and advancing means (18) acting at least on the compaction unit (9) for determining a positioning of the compaction unit (9) relative to the track.
