The rail is composed of rail head, rail thickness and rail bottom, and the width of the rail is called gauge (subject to the inner distance of the rail). There are currently three gauge types: standard gauge, wide gauge and narrow gauge. At present, the most widely used gauge in the world is 1435mm, which is called the standard gauge. 60% of the railways in the world use this common standard gauge. standard rail for railway
Standard rail was born in Britain, where railways were first used. It was proposed by British engineer Robert Stevenson and successfully persuaded train manufacturers to produce 1435mm gauge locomotives and vehicles. As the railway successfully designed by Stevenson is an imitation of others, the 1435mm gauge rail has gradually become popular all over the world.
On traditional railways, most countries in the world use standard tracks, concentrated in Western Europe, North America, North Africa and mainland China. According to statistics, about 60% of railway lines in the world are built with standard gauge. standard rail for railway
In addition, with the exception of Russia, Uzbekistan and Finland, almost all high-speed railways built in other countries adopt standard tracks.
Most high-speed rail technologies are based on standard rail development. Almost all the existing high-speed rail systems in the world use standard rail, including Japan and Taiwan of China, which use narrow rail, and Spain and Portugal, which use wide rail, which use traditional rail.
Countries that use narrow gauge in traditional railways all switch to standard gauge on high-speed railways, which can improve the stability under high-speed operation. standard rail for railway
Russia and Finland have adopted a 5-foot wide rail high-speed railway to make it compatible with their traditional railway tracks.
