What is the size of a single strip of rails in China 10

The size of a single rail in China is 1435 mm.

Article 38 of the Railway Law of the People's Republic of China.

The standard gauge of the railway is 1435 mm. New national railways must use standard gauges.

The gauge of narrow-gauge railways is 762 mm or 1000 mm.

Other technical requirements for new and reconstructed railways shall conform to national standards or industry standards.

China's rails are 1435 mm wide, and this width of the rails is called "quasi-rail", and in the mountainous areas of Yunnan (such as Kunming to Kaiyuan, which was built by the French) there are 1 meter narrow gauges, and the carriages are also shorter, making it easy to turn in the mountains.

The Railway Law of the People's Republic of China was passed by the 15th Session of the Standing Committee of the Seventh National People's Congress of the People's Republic of China on September 7, 1990, and is hereby promulgated to take effect on May 1, 1991. President of the People's Republic of China Yang Shangkun September 7, 1990 Railway Law of the People's Republic of China (Adopted at the 15th Session of the Standing Committee of the Seventh National People's Congress on September 7, 1990) Article 38 The standard gauge of railways is 1435 mm. New national railways must use standard gauges.

The gauge of narrow-gauge railways is 762 mm or 1000 mm. Other technical requirements for new and reconstructed railways shall conform to national standards or industry standards. The full length of the vehicle and the replacement length of the vehicle refers to the distance between the inside of the hook tongue at both ends of the vehicle, in meters.

For the convenience of practical work, it is customary to convert the length of the vehicle into the number of vehicles, that is, the quotient obtained by dividing the total length by 11 meters to express the converted length of the vehicle. i.e. change the length of the vehicle (m) 11 (m) Gauge The gauge is the minimum distance between the two strands of rail action within 16 mm below the top surface of the rail head. China's railways mainly use the standard gauge of 1435 mm.

In addition, the railway gauge of Taiwan is 1067 mm, and some of the railways of the Chengdu Railway Bureau are narrow gauges of 1000 mm. Seamless line The length of the ordinary sleeper in China is meters, and the turnout sleeper used for turnouts and the bridge sleeper used on the steel bridge have a variety of lengths such as plates and meters. Seamless line is to weld a number of standard length rails into each section of 800 1000 meters (can be longer) long rail line, its joints are few, and have the advantages of stable driving, wheel and rail wear and line maintenance and repair workload, etc., is one of the contents of track modernization.

Theoretically, the longer the length of the rail, the better, which not only reduces the impact and wear of the joints, but also reduces the labor intensity of laying. However, due to the constraints of manufacturing and transportation, the current standard length of steel rails in China is only 25m. However, railway employees took the approach of welding standard-length rails to long rails and "seamless" rails at the construction site, reducing joints and smoothing the line.

The track width in China is 1435mm.

In 1937, the International Association of Railways made a rule: the gauge of 1435 mm is the international standard gauge, the gauge above 1520 mm is broad gauge, and the gauge below 1067 mm is counted as narrow gauge. Today, although most countries use a 1435 mm wide gauge, there are still more than 30 different gauges.

The different standards of railway gauge will inevitably make it difficult for railway transportation to flow smoothly.

The 1435mm gauge is recognized as the international standard gauge, and about 60 70% of the world's railways (the United Kingdom, the United States, Canada, the Federal Republic of Germany, etc.) use the 1435mm standard gauge. The gauge greater than 1435mm is called broad gauge, such as the Soviet Union, Panama, Finland and other countries use this gauge.

The track width of China's high-speed railways is usually 1435 mm, which is the standard track width for most of the current express and freight railways.

In 1937, the International Railway Association made a rule: the 1435 mm gauge is the international standard gauge. Gauges that are wider than the standard gauge are called broad gauges, and those that are narrower than the standard gauges are called narrow gauges.

1. Gauge is the distance between two rails of a railway track. At present, there are more than 30 different gauges in the world, which are divided into normal gauge, broad gauge and narrow gauge.

2. In 1937, the International Railway Association formulated 1435mm as the standard gauge, that is, the general gauge, and 60% of the world's railways are standard gauges. This ordinary gauge is also known as the standard gauge or the international gauge. Gauges that are wider than the standard gauge are called broad gauges, and those that are narrower than the standard gauges are called narrow gauges.

Double-gauge or multi-gauge railways have three or four rails that allow trains of different gauges to travel.

The standard gauge used in China is 1435 mm, which is different from that of foreign countries. India, Pakistan, Argentina, Chile and other countries mainly use 1676mm wide gauge; Russia adopts a wide gauge of 1520mm; The United States, Canada and most European countries use the 1435mm standard gauge; Ghana, Congo, Tanzania, Zambia and other countries in Africa use 1067mm narrow gauge.

Including China, about 55% of the world's railway lines are built with standard gauge, and in addition, with the exception of Russia, Uzbekistan and Finland, almost all countries have built high-speed railways with standard gauge. There are more than 30 different gauges (track widths) in the world, which are roughly divided into broad gauge, standard gauge, and narrow gauge (including meter gauge and inch gauge). The light and heavy of vehicles are divided into light rail and heavy rail.
