STATUS REPORT-PRESTRESSED CONCRETE TIES

A series of four articles summarize the situation with concrete crossties in the U.S. in 1978. Prestressed concrete tie: The U.S. story from the beginning by G. M. Magee tells how as a researcher he helped to introduce the concept into the U.S.; after discussing such problems as interspersion with wood ties, designs of fasteners, tie pads and ballast, and with damage from derailments he concludes that an improved track structure can be achieved with concrete ties. Service tests on the "new" concrete ties by J. W. Weber describes recent inspections made of installations of these ties on the Alaska, Chessie, Santa Fe and Norfolk & Western. Fastenings for concrete ties describes nine designs involving threaded or threadless clips that clamp or are rail free to suit varying situations. What's happening among the concrete tie manufacturers describes the production and facilities of five North American organizations designing and manufacturing concrete ties.
