    The quantity of ballast tends to vary with gauge, with the wider gauges tending to have wider formations. The depth of ballast also tends to vary with the density of traffic, as faster and heavier traffic requires greater stability. The quantity of ballast also tends to increase over the years as more and more ballast is piled on. Some figures from an 1897 report are: • first class line 60 lb/yd (29.8 kg/m) rail 1,700 cu yd/mi (810 m /km).
