ABSTRACT A conveying or excavating chain arrangement (6) for a ballast bed cleaning machine (1), comprising an endless conveying or excavating chain (10) arranged on a machine frame (4) and guided in a vertically adjustable guide channel and connected to a chain drive (9). The guide channel has an excavating bar (26) located in operative use beneath the track (3) and in an inclined arrangement has an elevated discharge position (14) spaced apart from the excavating bar in the longitudinal direction of the machine. The excavating bar (26) is designed to be pivotable or adjustable in the horizontal plane in order to change the effective excavation width. Two excavating bars (26), designed so as to be mutually separate, are provided - forming in each case an independent excavating unit (7, 8,) having separate vertical and transverse adjustment drives (11, 12) - , wherein there are associated with each excavating unit (7, 8) an endless excavating chain (10) with a chain drive (9) and two longitudinal chain guide tracks (24, 25), each located on the same longitudinal side of the machine.
