Abstract: A ballast distributing and planing machine comprises an elongated machine frame supported on the track by undercarriages for mobility along the track in an operating direction, a ballast broom extending transversly across the track and mounted on the machine frame at a rear end thereof in the operating direction, and a ballast plow arrangement mounted on the machine frame. A ballast storage container is mounted on the machine frame and has at least one discharge opening enabling ballast stored in the container to be discharged onto the track, and a ballast discharge conveyor band is mounted immediately below each discharge opening and is arranged to close the opening, each conveyor band having a drive for moving the conveyor band in a conveying direction.

Abstract: A mobile machine for clearing and planing ballast comprises a machine frame, undercarriages supporting the machine frame for mobility on the railroad track, at least one vertically and transversely adjustable ballast clearing tool connected to the machine frame for clearing ballast laterally outwardly of a respective rail and for planing the ballast upon vertical and transverse adjustment of the tool, the tool being longitudinally adjustably mounted on the machine frame for adjustment in the direction of the railroad track supported by the ballast, and drives connected to the tool for vertically, transversely and longitudinally adjusting the tool.
