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 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 structure gauge, also called the minimum structure outline, is a diagram or physical structure that sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. It specifies the height and width of station platforms, tunnels and bridges, and the width of the doors that allow access to a warehouse ...
Platform height affects the loading gauge (the maximum size of train cars), and must conform to the structure gauge physical clearance specifications for the system. Tracks which are shared between freight and passenger service must have platforms which do not obstruct either type of railroad car.
For standard gauge railways, double stacking maximum height shall be 6.15 m (20 ft 2 in). For Indian gauge railways, double stacking maximum height shall be 7.1 m (23 ft 4 in), and minimum overhead wiring height shall be 6.5 or 6.75 m (21 ft 4 in or 22 ft 2 in) above rails.
1,000 mm (3 ft 3 + 3 ⁄ 8 in) gauge, it has over-100-pound rail (100 lb/yd or 49.6 kg/m) and a loading gauge almost as large as US non-excess-height lines. The line has a number of 4,000-horsepower (3,000 kW) locomotives and 200-plus-car trains.

The tracks are entirely grade-separated and have a generous loading gauge of 3,660 mm (12 ft 1 ⁄ 8 in) width and 7,100 mm (23 ft 3 + 1 ⁄ 2 in) maximum height allowing for the double-stacked shipping container on flatcars to be transported, in contrast to wellcars used in other countries for double-stack rail transport.
