The weight of a rail per length is an important factor in determining rails strength and hence axleloads and speeds Weights are measured in pounds per yard imperial units are used in Canada the United Kingdom and United States or kilograms per metre metric units are used in Australia and mainland Europe As a kilogram is approximately 22 lb and a metre is roughly 11 yards the pounds While ballast may not be at the top of anyone s list of rail topics it s literally part of the foundation of railroads and it can comprise more than 80 of the weight of the track structure Ballast performs several important functions it distributes weight keeps the ties in place allows water to drain away protects track from the effects
