CA 2252352

A ballast grading machine (1) comprising a machine frame (3) designed to travel on on-track undercarriages (2) is equipped with an adjustable ballast plough (20) for ballasting a track (6). Provided preceding the ballast plough (20) in the operating direction of the ballast grading machine (1) is a non-contact sensing unit (29) for detecting an actual ballast profile extending perpendicularly to the longitudinal direction of the track or machine. Associated with the ballast plough (20) are position sensors (25) for detecting a relative position change in relation to the machine frame (3). A control unit (31) has a memory unit for storing a desired ballast profile. This enables track sections with too little or too much ballast to be recognized and the ballast plough (20) to be controlled accordingly.
