摘要: A rail-lifting and ballast-spreading apparatus that may be employed to rehabilitate damaged tracks or aid rough in of new tracks, is described. The apparatus includes a track-lifting unit at a forward end thereof that includes an arm that is pivotable to extend forwardly and over a section of track in need of repair or ballast replenishment. Rail clamps are provided on a distal end of the arm that engage and travel along the rails as the apparatus moves forward. A conveyor provides a stream of ballast across the width of the tracks while the tracks are lifted and as the apparatus moves forward onto the now repaired tracks. A surge bin is provided to increase a rate of distribution of the ballast material by the conveyor over that available from the ballast-delivery consist.
