Rail Weights and Sizes
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 or kilograms per metre; the pounds-per-yard figure is almost exactly double the kilograms-per-metre figure. Rails in Canada, the United Kingdom and United States are described using imperial units. In Australia, metric units are used as in mainland Europe.
In rail terminology Pound is used synonymously with pounds per yard, e.g. a 132 pound rail means a rail of 132 lb/yd.

“We rail at trade, but the historian of the world will see that it was the principle of liberty; that it settled America, and destroyed feudalism, and made peace and keeps peace; that it will abolish slavery.”

“... the prevalent custom of educating young women only for marriage, and not for the duties and responsibilities consequent on marriage—only for appendages and dead weights to husbands—of bringing them up without an occupation, profession, or employment, and thus leaving them dependent on anyone but themselves—is an enormous evil, and an unpardonable sin.”
—Harriot K. Hunt (1805–1875)
