CALCULATIONS ON SUBSIDENCE OF TRACK BY "NEW THEORY ON TRACK DETERIORATION"

A theory of track deterioration based on subsidence of ballast and of subgrade has been investigated. An equation for deterioration of heavy traffic lines with continuous welded rail taking into consideration speed, traffic density, roadbed condition and other factors shows that subsidence of bad track is about four times that of good track.
