George Stephenson introduced the 1,435 mm (4 ft 8 + 1 ⁄ 2 in) gauge (including a belated extra 1 ⁄ 2 in (13 mm) of free movement to reduce binding on curves [16]) for the Liverpool and Manchester Railway, authorised in 1826 and opened 30 September 1830. The extra half inch was not regarded at first as very significant, and some early trains ...
The Washington Metro 4 ft 8 + 1 ⁄ 4 in (1,429 mm), the gauge is 1 ⁄ 4 inch (6 mm) less than 4 ft 8 + 1 ⁄ 2 in (1,435 mm) The trams in Nuremberg for one time nominally used 1,432 mm (4 ft 8 + 3 ⁄ 8 in), the gauge is 1 ⁄ 8 inch (3 mm) less than 4 ft 8 + 1 ⁄ 2 in (1,435 mm) The MTR uses 1,432 mm (4 ft 8 + 3 ⁄ 8 in) on most lines.
The international standard symbol for inch is in (see ISO 31-1, Annex A) but traditionally the inch is denoted by a double prime, which is often approximated by a double quote symbol, and the foot by a prime, which is often approximated by an apostrophe. For example; three feet, two inches can be written as 3 ′ 2″.
It had slightly larger 17-inch-diameter (430 mm) cylinders and a 25-foot-2 + 1 ⁄ 2-inch (7.684 m) wheelbase. When withdrawn in 1885 it was the end of Pearson's 4-2-4Ts. No. 12 followed in 1862 and returned to 16 + 1 ⁄ 2-inch (420 mm) cylinders and had a slightly shorter 25-foot-1-inch (7.65 m) wheelbase.
By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
During the storm siege, 2-4 inches of rain is likely to fall in the lower elevations along Interstate 5 in Washington and Oregon, with slow travel at times. However, much heavier rain will fall on ...

The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...
