HOLD-DOWN FASTENINGS FOR TIE PLATES, INCLUDING ELASTIC PADS UNDER PLATES; THEIR EFFECT ON TIE WEAR

Study is made of hold-down fastenings for tie plates, including elastic pads under plates, and their effect on tie wear, in an effort to extend the service life of ties and save cost. Service tests are reported to determine, from periodical measurement of tie plate penetration, track gage, curvature, cross levels and other observations, the relative effectiveness and economy of the several types of hold-down fastenings and tie pads, as to reduction in mechanical wear of ties and the maintaining of good track gage on curves. Initial gage measurements for original construction were taken in November 1974 and checked in August 1948; readings for the 1948 construction were taken on October, 1948. It is noted that when gage widening occurred, its cause was undetermined, but forthcoming tests will determine if the pads were a major contributing factor to the gage widening. Generally the gage in most test sections on the long curve held well. Tie plate penetration measurements are taken, but in many instances a tie plate does not become finally seated in one year.
