Track gauge. Track geometry is concerned with the properties and relations of points, lines, curves, and surfaces [1] in the three-dimensional positioning of railroad track. The term is also applied to measurements used in design, construction and maintenance of track. Track geometry involves standards, speed limits and other regulations in the ...
In rail transport, track gauge is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks.
Indian gauge (1,676 mm) This list presents an overview of railway track gauges by size. A gauge is measured between the inner faces of the rails. Narrow gauge (1,067 mm) Standard gauge (1,435 mm) Broad gauge (1,600 mm) The large network of narrow-gauge sugar cane light railways, almost all 610 mm (2 ft) gauge, is not shown, Rail gauge in ...
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 ...
Europe. Australia. A railway track (British English and UIC terminology) or railroad track (American English), also known as a train track or permanent way (often " perway " [1] in Australia), is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus ...
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.
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 ...
Adhesion railway. Driving wheel of steam locomotive. An adhesion railway relies on adhesion traction to move the train, and is the most widespread and common type of railway in the world. Adhesion traction is the friction between the drive wheels and the steel rail. [1] Since the vast majority of railways are adhesion railways, the term ...
