摘要： A pair of removal implements are mountable on a track supported work vehicle for movements between raised and lowered positions as well as movements longitudinally of ties disposed to support the tracks. Downwardly depending, blade-like implement elements on the removal implements are disposed to work simultaneously on the outside and inside of each track for removing ballast to the outside of the tracks. Supplementary implements including lateral extensions are rotatably mounted on each of the removal implements for movements from an inoperative position, during initial ballast removal operations, to an operative position during final ballast removing operations whereby ballast under the track is removed by the lateral extensions.
