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.
