THE EXPERIMENTAL DETERMINATION OF THE AXIAL AND LATERAL TRACK-BALLAST RESISTANCE

This paper presented a state-of-the-art survey of the various techniques for determining axial and lateral track-ballast resistance and described the experimental methods used in these investigations. The survey included a comparison of the results produced by several investigators. The discussion included data on the effect of compaction of ballast and the effect of an increase in ballast. Various methods of static and dynamic measurements of lateral and axial resistance by rails, ties, and ballast were presented.
