 | | The Standard gauge of 4 ft 8½ in (1435 mm) was chosen for the first main-line railway, the Liverpool and Manchester Railway (LandMR), by the British engineer George Stephenson, because it was the de facto standard for the colliery railways where Stephenson had worked. |
 | | The track gauge adopted by the mainline railways is 5 ft 3 in (1600 mm). |
 | | Iran to the west uses standard gauge, as does China to the east; to the south, Pakistan uses 1676 mm gauge, while to the north, the central Asian republics of Turkmenistan, Uzbekistan, and Tajikistan use 1520 mm gauge. |
