摘要：
A method and apparatus for removing ballast from beneath railroad tracks utilizes a horizontal undercutter disposed beneath the track to remove the ballast therefrom into a trench excavated by a cooperatively mounted trencher wheel. A horizontally disposed conveyor is located in the trench rearwardly of and adjacent the trench wheel to receive the ballast from the undercutter and to transport the ballast to the trencher wheel for removal thereby.
