ABSTRACT:
A ballast metering method and apparatus is disclosed which utilizes a rail mounted metering hopper having a set of forward discharge outlets for directing ballast laterally and downwardly beneath the rails under the pressure of a volume of ballast retained in the hopper. This volume is maintained at a continuously maintained level by selective addition of ballast to the hopper. The discharged ballast forms a pair of spaced apart windrows beneath the rails which is graded to a predetermined height by a sub-track grader blade associated with the hopper. A center discharge opening at the rear of the hopper allows ballast to be directed between the graded windrows. A pair of lateral chutes permit discharge of ballast outwardly of the rails.
