摘要： A reenforced precast concrete railroad tie having rail supporting and anchoring plates integrally molded thereinto. The rail plates in one form have a pair of L-shaped anchor and reenforcing rods welded to each of the gage and field sides of the tie plate, with portions of the rods having substantial longitudinal length to supplement other reenforcing rods molded longitudinally within the tie. The tie plate is further provided on its generally planar underside with either a welded on or integrally formed fixed threaded nut depending between each pair of the L-shaped rods at the gage and field sides to accomodate complementally threaded bolts cooperating with rail clip fasteners, the bolts passing through tie-plate-formed apertures correspondingly aligned with the threaded opening in the nuts. In another form the L-shaped rods are replaced by inverted T ot pi shaped rods. A novel apparatus subassembly and related method utilizing presently conventional components and techniques in a novelly improved manner is also contemplated herein.
