A tie delivering system for use in an apparatus for constructing railroad track sections comprising a support structure including a conveying path, means for conveying a plurality of longitudinally spaced ties along said path, means for delivering a pair of laterally spaced rails above said ties such that the rails are initially vertically spaced above the ties and come to rest on the ties and means for delivering an assembled track section from the path. The tie delivery system includes a tie storage structure mounted on said support structure at an elevation higher than the conveying means and arranged to hold ties in a position parallel to the rails, an elongated tie receiving chute extending downwardly from said tie support structure between and parallel to said rails, means associated with said chute for releasably holding a tie therein, a tie receiving turntable positioned below said chute for receiving a tie released from the chute, said turntable having an elongated tie receiving opening extending vertically therethrough and said turntable being rotatable through 90 DEG in a horizontal plane positioned below said rails and above said conveying path, the rotation being between a location in which the turntable opening is in alignment with the chute and a location in which the turntable opening is longitudinally at right angles with the rails and means associated with said turntable opening for holding a tie therein and releasing the tie to be deposited onto the conveyor when the turntable opening is at right angles with the rails.
