ABSTRACT:
A method and apparatus for reconditioning ballast along a railroad track utilizes lateral excavators to excavate the ballast adjacent the track ahead of an undercutter which excavates beneath the track. The ballast from adjacent the track is discharged below the track without processing, while the ballast taken from beneath the track is processed by a cleaning screen to recover reuseable ballast which is discharged outwardly of the center of the track.
