MOBILE BALLAST CLEANING MACHINE ARRANGEMENT Abstract of the Disclosure A mobile machine arrangement for excavating ballast from a ballast bed, for cleaning the excavated ballast and for redistributing the cleaned ballast to the ballast bed, comprises a first, elongated machine frame and a second machine frame supported for mobility on a track. Mounted on the first machine frame are a track lifting device, a ballast excavating chain including a transverse course insertable in a central ballast bed portion under the track for excavating ballast from the central ballast bed portion, and a first ballast cleaning screen arranged to receive the excavated ballast from the excavating chain. The second machine frame precedes the first machine frame in the operating direction and is linked thereto, and mounted on the second machine frame are a ballast excavating device at each side of the track for excavating ballast from each ballast bed shoulder portion and for conveying the excavated shoulder ballast, a second ballast cleaning screen preceding the first ballast cleaning screen in the operating direction and arranged to receive the conveyed ballast from the ballast excavating devices. A respective ballast redistributing conveyor is arranged for receiving the cleaned ballast portion from each ballast cleaning screen and for redistributing the cleaned ballast portion in a respective ballast bed portion behind the transverse ballast excavating chain course in the operating direction, and another conveyor is mounted on the first and second machine frames for selectively receiving the waste portions from the first and second ballast screens and for conveying the received waste portions forwardly in the operating direction along a conveying path.
