Unlike some other uses of iron and steel, railway rails are subject to very high stresses and have to be made of very high quality steel. It took many decades to improve the quality of the materials, including the change from iron to steel. Minor flaws in the steel that pose no problems in reinforcing rods for buildings, can, however, lead to broken rails and dangerous derailments when used on railway tracks.

By and large, the heavier the rails and the rest of the trackwork, the heavier and faster the trains these tracks can carry.
The rails represent a substantial fraction of the cost of a railway line. Only a small number of rail sizes are made by the steelworks at the one time, so a railway must choose the nearest suitable size. Worn, heavy rail from a mainline is often cascaded down to branchline, siding or yard use. A branch line is a relatively minor railway line which branches off a more important through route. ...
A siding, in general rail terminology, refers to a section of rail used to store stationary rolling stock perhaps whilst it is loaded or unloaded, or alternatively, a short length of rail that provides access to and from factories, mines, quarries, wharves, etc. ...

Rail sizes Rails in Canada, the United Kingdom, and United States are still described using imperial units. However, in Australia they are now described in metric units and always have been on mainland Europe. Continental Europe, also referred to as mainland Europe or simply the Continent, is the continent of Europe, explicitly excluding European islands and, at times, peninsulas. ...
Depending on the use of imperial or metric units, rail sizes are usually expressed in terms of pounds per yard or kilograms per metre. Coincidentally, the pounds-per-yard figure is almost exactly double the kilograms-per-metre figure, making rough conversions easy. The Imperial units or the Imperial system is a collection of English units, first defined in the Weights and Measures Act of 1824, later refined (until 1959) and reduced. ...

Europe Rails are made in a large number of different sizes. Some common European rail sizes include: - 40 kg/m (81 lb/yd)
- 50 kg/m (101 lb/yd)

- 60 kg/m (121 lb/yd)
| | In the countries of former USSR 65 kg/m rails are common. Thermally hardened 75 kg/m rails also have been used on heavy-duty railroads like Baikal-Amur Mainline, but have proven themselves deficient in operation and were mainly rejected in favor of 65 kg/m rails[1].

History Cross sections of early rails Early rails were used on horse drawn wagonways. In the early days the rails were flanged (i.e 'L' shaped) with the wagon wheels being flat. Over time it was realised that flanged wheels with flat rails worked better. Wagonways are the horses, equipment, and tracks used for hauling wagons which preceded steam powered railways. ...
Early rails were sometimes strap-iron rails, which consisted of thin strips of iron strapped onto wooden rails. These rails were too fragile to carry heavy loads, but because the initial construction cost was less, this method was sometimes used to quickly build an inexpensive rail line. Strap rails sometimes separated from the wooden base and speared into the floor of the carriages above, creating what was referred to as a "snake head." However, the long-term expense involved in frequent maintenance outweighed any savings.
The earliest in general use were the so-called cast iron "fishbelly" rails from their shape. In time it became possible to roll longer lengths in wrought iron. The cross-section varied widely from one line to another, but were of three basic types as shown in the diagram. The parallel cross-section may also be called Bullhead. Cast iron usually refers to grey cast iron, but can mean any of a group of iron-based alloys containing more than 2% carbon (alloys with less carbon are carbon steel by definition). ...

Early fishbelly metal rails made from cast iron were brittle and broke easily. They could only be made in short lengths which would soon become uneven. By 1840, wrought iron in longer lengths replaced cast iron as rolling techniques improved. The first steel rails were made in 1857 by Robert Forester Mushet, who laid them at Derby station in England. Steel was a much stronger material, which steadily replaced iron for use on railway rail and allowed much longer lengths of rails to be rolled.
