Abstract
Ballast is removed from beneath railroad ties in accordance with a ballast treating method and apparatus without disturbing the ballast in the cribs between adjacent ties, and is deposited into a trench formed along the railway. The crib ballast is likewise removed and deposited in the trench. A plow structure used for the ballast removal operation has cutting blades curved toward the trench and disposed with their leading ends lying along a line sloping rearwardly away from the trench. The rail vehicle which supports the plow structure is stabilized against transverse forces imposed on the vehicle during the ballast removal operation, and the plow itself is likewise stabilized against such forces.
