TRAFFIC, MILLIONS OF WHEEL TONS/YEAR

Figure 11.2 The effect of traffic density on rail wear is plotted to show the influence of the environment and
type of traffic. Level of atmospheric pollution is an important controlling factor. Rail side wear is one to three
times greater than vertical wear on straight track, and increases as the radius of the curve diminishes below
1000 metres
