Track gauge. Originally, various track gauges were used in the United States. Some railways, primarily in the northeast, used standard gauge of 4 ft 8⁄2 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 ...
v. t. e. 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.

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 ...
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.
Model railway scales and gauges are standardized in NEM 010, [1] which covers several gauges for each scale. Narrow gauges are indicated by an additional letter added after the base scale as follows: no letter = standard gauge (1,250–1,700 mm or 49.2–66.9 in) m = metre gauge (850–1,250 mm or 33.5–49.2 in) e = narrow gauge (650–850 mm ...
OO gauge. OO gauge or OO scale (also, 00 gauge and 00 scale) is the most popular standard gauge model railway standard in the United Kingdom, [1] outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards (4 mm to 1 ft (304.8 mm), or 1:76.2), and the only one to be marketed by major manufacturers. The OO track ...
About 60% of the world's railways have a track gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm) known as "standard gauge", but there are also narrow-gauge railways where the track gauge is less than standard and broad-gauge railways where the gauge is wider. In a similar manner, a scale model railway may have several track gauges in one scale.
