In civil engineering, clearance refers to the difference between the loading gauge and the structure gauge in the case of railroad cars or trams, or the difference between the size of any vehicle and the width/height of doors, the width/height of an overpass or the diameter of a tunnel as well as the air draft under a bridge, the width of a lock or diameter of a tunnel in the case of watercraft.
The code also defines the clearance that is shorter than the physical clearance to account for sag curves, bridge deflection and expected settlements with a recommendation of minimum clearance of 5 metres (16 ft 5 in). [2] In UK, the "standard minimum clearance" for structures over public highways is 16 feet 6 inches (5.03 m). [3]
The standard defines static envelopes for trains on the national network as T, T c and T pr. The static profile 1-T is the common standard on the complete 1520 mm rail network including the CIS and Baltic states. The structure clearance is given as S, S p and S 250. There is a tradition that structure clearance is much bigger than the common ...
The standard gauge rail network in Eastern Asia is built to a minimum width of 3,400 millimetres (11 ft 2 in), and the Chinese CRH2 as well as the Japanese 0 Series Shinkansen have a width of 3,380 millimetres (11 ft 1 in). Similarly the tracks in Sweden are built to 3,400 mm (clearance SE-A and SE-B) just as the broad-gauge network under ...
In 1895, the Railway Signaling Club was organized at a meeting in Chicago, Illinois, and created a code of rules governing the operation of interlockings. In 1919, the Signaling Club became the Signal Division of the newly created American Railway Association (ARA) and the Telegraph Superintendents became its Telegraph and Telephone Section.
The Railway Regulation (Gauge) Act 1846 [1] (9 & 10 Vict. c. 57) or the Regulating the Gauge of Railways Act 1846 or the Gauge of Railways Act 1846 is an act of the Parliament of the United Kingdom, that was designed to standardise railway tracks.

Gauntlet tracks can be used to provide horizontal clearance to a fixed obstruction adjacent to a track such as a cutting, bridge, or tunnel.Frog gauntlets are also commonly used when a rail line's capacity is increased by the provision of an additional track, but cost or other factors prevent the widening of the bridges.
