But while the stone Hengoed Viaduct survived, a structural survey of the cast-iron Crumlin Viaduct showed its poor state, and resultant need for high investment to secure its future, let alone ongoing maintenance costs. The decision was therefore made to dismantle it because, by then, housing had extended into the lower valley area. [5]
The rail profile is the cross sectional shape of a railway rail, perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section approximate to an I-beam, but asymmetric about a horizontal axis (however see grooved rail below). The head is profiled to resist wear ...

Cast iron rails, 4 feet (1.2 m) long, began to be used in the 1790s and by 1820, 15-foot-long (4.6 m) wrought iron rails were in use. The first steel rails were made in 1857 and standard rail lengths increased over time from 30 to 60 feet (9.1–18.3 m).
Heavier rail can support greater axle loads and higher train speeds without sustaining damage than lighter rail, but at a greater cost. In North America and the United Kingdom, rail is graded in pounds per yard (usually shown as pound or lb), so 130-pound rail would weigh 130 lb/yd (64 kg/m). The usual range is 115 to 141 lb/yd (57 to 70 kg/m).
Railway costing is the calculation of the variable and fixed costs of rail movements. Variable costs are those that increase or decrease with changes in the traffic volumes or service levels and include fuel, maintenance and train crew costs, for example. Fixed costs are normally associated with items such as head office, interest charges and ...
