A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. [ 1 ]
The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track, usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below the top of the rail head in order to clear worn corners and allow for rail heads having sloping ...

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 ...

The vast majority of North American railroads are standard gauge (4 ft 8 + 1 ⁄ 2 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.
The official name of this gauge is the Gabarit passe-partout international (PPI, literally "pass-everywhere international gauge"), and it came into force in 1914. The European (Berne) loading gauge is usually 3,150 mm (10 ft 4 in) wide by 3,175 mm (10 ft 5.0 in) rising to 4,280 mm (14 ft 1 in) in the centre.
