width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – a "gauge break" – loads had to be unloaded from one set of rail cars and re-loaded onto another, a time-consuming and expensive process. The result was the adoption throughout a large part of the world of a "standard gauge" of , allowing interconnectivity and interoperability.
Origins
A popular legend that has been around since at least 1937 traces the origin of the gauge even further back than the coalfields of northern England, pointing to the evidence of rutted roads marked by

Research however has been undertaken which supports the hypothesis that "the origin of the standard gauge of the railway might result from an interval of wheel ruts of prehistoric ancient carriages".
In addition, while road-travelling vehicles are typically measured from the outermost portions of the wheel rims (and
there is some evidence that the first railways were measured in this way as well), it became apparent that for vehicles travelling on rails it was better to have main
wheel flanges that fit ''inside'' the rails, and thus the minimum distance between the wheels (and, by extension, the inside faces of the
rail heads) was the important one.
There was never a standard gauge for horse railways but there were rough groupings: in the north of England none was less than .

Gauge Act ruled that new passenger-carrying railways in Great Britain should be built to a standard gauge of , and those in Ireland to a new standard gauge of . In Great Britain, Stephenson's gauge was chosen on the grounds that existing lines of this gauge were eight times longer than those of the rival (later ) gauge adopted principally by the Great Western Railway. It allowed the broad-gauge companies in Great Britain to continue with their tracks and expand their networks within the "Limits of Deviation" and the exceptions defined in the Act. After an intervening period of
mixed-gauge operation (tracks were laid with three rails), the Great Western Railway finally completed the
conversion of its network to standard gauge in 1892. In North East England, some early lines in colliery (

Track gauge in the United States.
In continental Europe, France and Belgium adopted a gauge (measured between the midpoints of each
rail's profile) for their early railways. The gauge between the interior edges of the rails (the measurement adopted from 1844) differed slightly between countries, and even between networks within a country (for example, to in France).
The first tracks in Austria and in the Netherlands had other gauges ( in Austria for the Donau Moldau line and in the Netherlands for the
Hollandsche IJzeren Spoorweg-Maatschappij), but for interoperability reasons (the first rail service between Paris and Berlin began in 1849, first Chaix timetable) Germany adopted standard gauges, as did most other European countries.
The modern method of measuring rail gauge was agreed in the first Berne rail convention of 1886, according to the "Revue générale des chemins de fer, July 1928".
