What are the best railways in China?

China has built many railways. What are they?

The first railway built by China people and successfully preserved for practical application was the Tangxu Railway.

China's first high-speed maglev railway is Pudong Expressway maglev railway. The railway is 30 kilometers long and runs at an average speed of 60-70 meters per second. Except for the two stages of acceleration and deceleration, the speed of the train is above 300 kilometers per hour most of the time, and it takes more than 20 seconds to reach the maximum design speed of 430 kilometers per hour.

The first railway designed and built in New China is chengdu-chongqing railway, which is the first railway built entirely with domestic materials.

The first cross-sea railway in China is the Guangdong-Hainan Railway, which was officially opened on June 7, 2003. The total investment is 4.5 billion yuan, which consists of the "two lines and one crossing" project, namely Zhanjiang-Hai 'an Railway in Guangdong Province 139 km, Haikou-Chahe West Ring Railway in Hainan Province 182 km, and Qiongzhou Strait Railway Ferry is 24 km.

The first desert railway in China was baotou-lanzhou railway, which crossed the vast Tengger Desert. After civil defense and sand control by local people, a green barrier has been built along the railway, which has been safe and smooth for 4 1 year. This sand control project is known as the "miracle of the world" and won the "Global 500 Best Environmental Protection Award" of the United Nations.

The first electrified railway in China is baoji-chengdu railway, which is also the first railway connecting Sichuan and the whole country. The railway starts from Baoji, Shaanxi Province in the north, passes through Lueyang and Yangping, enters Sichuan, and then passes through Guangyuan to Chengdu, with a total length of 669 kilometers and 374 kilometers in Sichuan.

Beijing-Kowloon Railway is the main railway line with the largest investment, the longest mileage and the shortest construction period in the history of railway construction in China. The main highway is 2397 kilometers long.

China's first railway built in the restricted area was chengdu-kunming railway. The route in chengdu-kunming railway was once a "forbidden zone" that foreign experts asserted that railways could not be built at all. This railway runs through Chengdu to Kunming, with a total length of 1.085 km, and a section of 1/3 is in the earthquake zone. The mountains along the railway are high and the valleys are deep, and the rivers are swift. The geology is complex and the climate is changeable. Hundreds of mountains were dug, 427 tunnels were built and 653 bridges were erected. The total length of the bridge and tunnel is more than 400 kilometers, with an average of 1.7 kilometers.

The railway called "half flame, half iceberg" refers to the southern Xinjiang railway in China. The southern Xinjiang railway passes through Turpan basin, one of the lowest places, and enters the extremely hot and cold Tianshan mountain area. The total length of the railway is 476 kilometers, except Gobi desert and saline-alkali land, more than half of the whole line is deep mountain canyon, and the curve accounts for 80%.

The trunk line with the most beautiful scenery and steepest slope in China is the Nanning-Kunming Railway. Nanning-Kunming Railway starts from Nanning in the east, reaches Kunming in the west and connects Guo Hong in the north, with a total length of 899.7 kilometers. It is a national first-class electrified railway trunk line connecting Guangxi, Guizhou and Yunnan. Along the railway, there are high gorges and deep valleys, and the landscape is wonderful. This trunk line has created many world firsts and Asian firsts. These include: Gao Qiao-qingshui river bridge, the world's first railway, Jiazhujing Tunnel, the first dangerous tunnel in Asia, the first wall in Asia-the anchor pile sheet wall of Shitouzhai Station, and Mihualing Tunnel, the longest electrified tunnel on single track.

The highest and most anticipated trunk line in the world is the Qinghai-Tibet Railway. The Qinghai-Tibet Railway was built on the Qinghai-Tibet Plateau, the roof of the world, with an altitude of about 3,000 meters and a maximum of 5,000 meters. It is a plateau railway in China and the highest railway in the world at present. Although its engineering quantity is not as good as that of chengdu-kunming railway, the climate and natural conditions on the plateau are very bad, the geology is very complicated and the construction is very difficult. Because the completion of this railway will greatly reduce the difficulty and tolls in and out of Tibet, it is not only the most anticipated route for tourists looking forward to their trip to Tibet, but also the most anticipated road for people in Xizang.
