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 clearance for overhead signs is 5.7 metres (18 ft 8 in) and the clearance for the soffit or underside of overpasses is 10 metres (32 ft 10 in). [ 6 ] In South Africa and the southern region of Africa, the minimum vertical clearance of modern bridges is 5 metres (16 ft 5 in), although the legal height limit of road vehicles is still at 4.3 ...
The clearance space between a train and the tunnel is often small. Pictured is a London Underground Northern line 1995 Stock train emerging from the tunnel north of Hendon Central station. A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads.
In Erie, Pennsylvania, the 6 ft (1,829 mm) Erie Railroad terminated while adjacent railroads used 4 ft 10 in (1,473 mm) gauge, also known as "Ohio gauge." That led to the Erie Gauge War in 1853–54, when the Erie mayor and citizens temporarily prevented a gauge standardization, because there would then be less trans-shipping work and through ...

The contiguous rail network in North America has a minimum width of 3,250 mm (10 ft 8 in) and a minimum height of 4,620 millimetres (15 ft 2 in). 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 ...
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the 1,435 mm (4 ft 8 + 1 ⁄ 2 in) used by standard-gauge railways.. Broad gauge of 1,520 mm (4 ft 11 + 27 ⁄ 32 in), more known as Russian gauge, is the dominant track gauge in former Soviet Union countries (CIS states, Baltic states, Georgia, Ukraine) and Mongolia.
In Canada, a Clearance is the equivalent to a Track Warrant. Direct Traffic Control Direct Traffic Control, or DTC, is similar to TWC, except that the rail line is divided up into predefined blocks—somewhat similar to ABS blocks without the signals—and dispatchers authorize trains to proceed in a specified number of blocks. Only one train ...
