RECOMMENDATIONS ON NUMBER AND PLACING OF ANTI-CREEPERS FOR VARIOUS CONDITIONS

The rail creepage measurements were made from reference stakes set at 1/8-mile intervals. Considering the performance of the anchorage methods in respect to holding the rail against creepage and maintenance of line and gage during the test period. Test sections have shown equally good results. Some local condition in section G-2 probably caused the larger westward movement of the south rail. Methods H and I of the arrangements initially installed, have shown superior performance throughout the 33-month test, and with only 8 and 10 anchors, respectively. The problem of anchoring rail in track carrying traffic in both directions is considerably different from that on tracks with traffic in only one direction. In a majority of the miles in this test the south and north rails have moved in opposite directions. It therefore seems logical to anchor the rail to resist creepage in both directions. Further, for the best conditions of maintenance, staggered anchoring seems undesirable because of the excessive tie skewing and the adverse affect on the line and gage of the track. Also, for greater efficiency in resisting the rail movement immediately, the rail anchors should be boxed. However, an adequate number of anchors should be used to arrest creepage in both directions and to avoid having the anchor ties churn and lose their trmping. To obtain maximum rail restraint with the minimum number of anchors they should be spaced evenly throughout each half panel, as in most of the methods where consecutive ties were anchored the resistance of one crub of ballast proved to be insufficient to hold the anchored tie in place.
