A ballast cleaning machine comprises a first machine frame and a second, trailing machine frame linked thereto. Ends of the machine frames are supported on the track by undercarriages for movement of the machine in an operating direction. A vertically and laterally adjustable endless excavating chain as well as a track lifting device is mounted on each machine frame. An upper layer of the ballast bed is excavated by the first excavating chain, the track is lowered to the remaining ballast bed layer, and the remaining ballast bed layer is immediately thereafter excavated by the second excavating chain.
