POLYETHYLENE TIE PLATES PASS LAB, SERVICE TESTS, REGULAR USE BEGINS

Specimens have survived rolling-load machine tests, extremes of heat and cold, exposure to water and sand, chemical agents and ultraviolet rays, and severe load conditions in actual service. The high-density polyethylene tie plate is injection molded from a formulation of Super-Dyland and weigh 1 1/2 lb each, as compared with 18 lb for the 13-inch steel tie plate. Field testing includes a range from industrial tracks to heavy-traffic main lines. Now Koppers, the manufacturer, reports increasing interest in the tie plate for use in surface tracks of rapid transit lines.
