In Portugal, there are three railway loading gauge standards for conventional (iberian gauge) railways: Gabarito PT b, Gabarito PT b+ and Gabarito PT c. Gabarito PT b (also called CPb) and Gabarito PT b+ (also called CPb+) allow rail cars to be 3.44 m (11 ft 3.5 in) wide with a permitted height of 4.5 m (14 ft 9 in), although CPb+ has a ...
The Berne Gauge [1] or Berne Convention Gauge is an informal but widely used term for the railway loading gauge considered the standard minimum loading gauge in most of Europe. The term arises from the international railway conference held and consequent convention signed in Bern , Switzerland in 1912.
Track gauge or rail gauge (also known as track gage in North America [8]) is the distance between the inner sides (gauge sides) of the heads of the two load bearing rails that make up a single railway line. Each country uses different gauges for different types of trains.
Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.

A related but separate gauge is the loading gauge: a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. The difference between these two gauges is called the clearance .
During the "gauge war" with the Great Western Railway, standard gauge was called "narrow gauge", in contrast to the Great Western's 7 ft 1 ⁄ 4 in (2,140 mm) broad gauge. The modern use of the term "narrow gauge" for gauges less than standard did not arise for many years, until the first such locomotive-hauled passenger railway, the Ffestiniog ...
The choice was often not between a narrow- and standard-gauge railway, but between a narrow-gauge railway and none at all. Broader gauge railways are generally more expensive to build, because they are usually heavier in construction, use larger cars and locomotives (larger loading gauge), as well as larger bridges, larger tunnels (larger ...
