ABSTRACT:
A railroad tie 10 is described. The tie includes elongated side surfaces 23 with a plurality of ballast locking indentations 34 formed therein. The indentations converge from open upward ends 35 to reduced bottom ends 36. The configuration of the locking indentations at the bottom ends is such that the indentations will receive the maximum aggregate size within the ballast. The tie body, provided with the indentations, and relationship of the sides 23 to the indentations 34 is such that maximum resistance is offered by the tie to longitudinal movement of the tie in the ballast with respect to the tie length dimension.
