Abstract
Track maintenance apparatus for use in railroad track maintenance utilizes a forward cribber unit to remove ballast from between the crossties and a rear adzer unit to smoothen any irregularities in the crosstie surface during a track re-laying operation. A single worker can perform both the cribbing and adzing tasks without dismounting from the apparatus.
