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

The service test installations of hold-down fastenings and tie pads on the Louisville & Nashville Railroad and Illinois Central Railroad and tests with the tie wear machine in the engineering Laboratory at the Research Center are covered in this report. The primary purpose of conducting these tests is to determine the effectiveness and economy of various types of hold-down fastenings, tie pads, etc. as related to tie life, regaging and readzing curves. The gage of test curves is described. Tie coatings are discussed. An in service evaluation of the performance of seven brands of tie pads is presented. This test demonstrates that softwood ties should be protected with the type of pads that retain a long term seal. Tie plate penetration measurements are obtained in a 15.6 year tests of hold-down fastenings. Included in this test are creosoted pine, gum, and oak ties. Cut spikes and screw spikes with double-coil washers are used with 13-in plates and 14 3/4-in plates. There has been no maintenance of the fastenings for six years, when the screw spikes were retightened out of face with a power wrench. At that time 20 percent of the screw spikes in the pine ties were reported to be stripped. This figure has increased considerably in the section with 14 3/4-in plates.
