An articulated ballast cleaning system utilizes a pair of ballast cleaners each dedicated to cleaning only a portion of the ballast bed of a railroad track, such that one cleans the peripheral ballast while the other cleans the center ballast. Spoil or waste ballast is conveyed forwardly along the apparatus for disposal, while cleaned ballast is conveyed rearwardly for replacement aft of an undercutter device. Fresh ballast may be conveyed forwardly along the apparatus to supplement the cleaned ballast. |
