A standard-gauge railway is a railway with a track gauge of 1,435 mm (4 ft 81⁄2 in). The standard gauge is also called Stephenson gauge (after George Stephenson), international gauge, UIC gauge, uniform gauge, normal gauge in Europe, [1][2][3][4][5] and SGR in East Africa. It is the most widely used track gauge around the world, with about 55 ...
Australia. 4 ft 8 in gauge railways are railways with a track gauge of 4 ft 8 in / 1,422 mm. This gauge is 1⁄2 inch (13 mm) less than 4 ft 81⁄2 in ( 1,435 mm) standard gauge The first such railways were the Killingworth Railway [ 1][ 2] and the Stockton and Darlington Railway [ note 1]
Track gauge. Originally, various track gauges were used in the United States. Some railways, primarily in the northeast, used standard gauge of 4 ft 8⁄ in (1,435 mm); others used gauges ranging from 2 ft (610 mm) to 6 ft (1,829 mm). As a general rule, southern railroads were built to one or another broad gauge, mostly 5 ft (1,524 mm), while ...
Track gauge. The vast majority of North American railroads are standard gauge (4 ft 8⁄ in / 1,435 mm). Exceptions include some streetcar, subway and rapid transit systems, mining and tunneling operations, and some narrow-gauge lines particularly in the west, e.g. the isolated White Pass and Yukon Route system, and the former Newfoundland Railway.
His chosen rail gauge, sometimes called "Stephenson gauge", [i] was the basis for the 4-foot-8 + 1 ⁄ 2-inch (1.435 m) standard gauge used by most of the world's railways. Pioneered by Stephenson, rail transport was one of the most important technological inventions of the 19th century and a key component of the Industrial Revolution.
In October 2019, the North Carolina Railroad Company began work to raise the bridge by 8 inches (0.20 m) as part of a $500,000 project to improve safety and reduce damage to the span. The bridge was raised to a new height of 12 feet 4 inches (3.76 m), the maximum clearance that would not affect the grades of nearby crossings.
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the 1,435 mm (4 ft 8 + 1 ⁄ 2 in) used by standard-gauge railways.. Broad gauge of 1,520 mm (4 ft 11 + 27 ⁄ 32 in), more known as Russian gauge, is the dominant track gauge in former Soviet Union countries (CIS states, Baltic states, Georgia, Ukraine) and Mongolia.
A third locomotive, Trotter, was delivered to the Dundee and Newtyle Railway by James Stirling and Co. on 3 March 1834 and had driving wheels of 4 feet 6 inches (137 cm), though these were subsequently changed to 4 feet 8 inches (142 cm). [5] It weighed 7 long tons 3 cwt 2 qr (16,070 lb or 7.29 t). [5]
