<p>An articulated ballast cleaning system utilizes a pair of ditcher wheels (26, 27) each dedicated to removing only the peripheral ballast from adjacent the ends of crossties (14). Undercutter (42) removes the ballast from beneath the center of the crossties (14). A screen cleaner (31) is provided to separate spoil from reusable ballast removed by the ditcher wheels (26, 27) whereas, ballast cleaner (41) is provided to separate spoil from reusable ballast removed by undercutter (42). The reusable ballast is cleaned by screen cleaner (31) and ballast cleaner (41). Spoil or waste ballast is conveyed forwardly along the apparatus for disposal, while cleaned ballast is conveyed rearwardly for replacement aft of the undercutter (42). Fresh ballast may be conveyed forwardly along the apparatus to supplement the cleaned ballast.</p> |
