Where: gt = standard track gage at a point “5/8” (15.9 mm) below top of rail = 56.5" (1,435.1 mm) gw = minimum gage of wheel set between backs of flanges = 53” (1,346.2 mm) fn = minimum thickness of new wheel flange = 1.15625” (29.369 mm) for narrow flange or = 1.375" (34.9 mm) for wide flange Note: The conversions are not in the ...
Crosslevel (or 'cross level') is the measurement of the difference in elevation (height) between the top surface of the two rails at any point of railroad track. The two points (each at the head of each rail) are measured at by the right angles to the reference rail. Since the rail can slightly move up and down, the measurement should be done ...
Cable is very strong in tensile strength, with a breaking strength in excess of 1000 lbs for these types of uses, and is a suitable in-fill material for a railing ("guard" in ICC codes). Typical diameters are 1/8", 3/16" for residential and 3/16" and 1/4" for commercial applications. [5]
Comparison of 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge (blue) and 3 ft 6 in (1,067 mm) (red) width; the difference is 14.5 in (370 mm), or about 26 per cent of standard gauge. 1,067 mm ( 3 ft 6 in ) between the inside of the rail heads, its name and classification vary worldwide and it has about 112,000 kilometres (70,000 mi) of track.

If the difference between the two gauges is large enough – for example between 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge and 3 ft 6 in (1,067 mm) – three-rail dual-gauge is possible, but if not – for example between 3 ft 6 in (1,067 mm) and 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge – four rails must be used. Dual-gauge rail lines ...

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). Rails were typically specified by units of weight per linear length and these also increased.
