The Portland Company was formed to build locomotives of this gauge for use on the local rail system. [3] The gauge was known as "Texas gauge" while required by Texas law until 1875, [4] and used by the New Orleans, Opelousas and Great Western Railroad (NOO&GW) until 1872, and by the Texas and New Orleans Railroad until 1876. The New England ...
In 1886, the southern railroads agreed to coordinate changing gauge on all their tracks. After considerable debate and planning, most of the southern rail network was converted from 5 ft (1,524 mm) gauge to 4 ft 9 in (1,448 mm) gauge, then the standard of the Pennsylvania Railroad, over two days beginning on May 31, 1886. Over a period of 36 ...
The horizontal alignment (or alinement in the United States) is done by using a predefined length of string line (such as 62-foot in the US and 20 meters in Australia [5]) to measure along the gauge side of the reference rail. It is the distance (in inches or millimeters) from the midpoint of the string line to the gauge of the reference rail.
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.

For example, the Federal Railroad Administration in the US specifies that the actual gauge of a 1,435 mm track that is rated for a maximum of 60 mph (96.6 km/h) must be between 4 ft 8 in (1,422 mm) and 4 ft 9.5 in (1,460 mm). [24]
