New World Speed Record on Rails
The record speed of rail transport in 574 km \ h kept since 2007
So far in 2014, the Chinese CIT500 experimental high-speed train on tests at the experimental section of the route near Qingdao with a length of 100.8 kilometers set a new speed record of 605 km / h
It is a little history, cost and prospects of development of the Chinese railways - under the cut
In general, the writing of the topic was pushed by a comment by Mad__Max , who asked a very reasonable question about the cost of Chinese railways. I tried to figure it out.
Well, the background of the question can, in principle, be omitted. Everyone already knows - the world's longest high-speed rail network, 2,200 km from Beijing to Guangzhou in 8 hours, a sharp jump from locomotives (the last locomotive was launched in 2005) to high-speed trains (the first line was commissioned in 2008) etc.
Today, each provincial capital (except for quite deaf Westerners) is connected to a network of high-speed railways, about 45% are highways with a design speed of 200-250 km / h, 55% - up to 350 km / h. After the accident of 2008 on the Wuhan-Guangzhou highway, the maximum speed of trains was reduced from 350 km / h to 300 to eliminate the causes of the accident and the improvement of trains. CIT500, in principle, should become the first train, for which speed limits will be lifted in 2016 and it will ride at a speed of 350-380 km / h.
As for the cost, the question turned out to be ambiguous. The undisputed leader in the cost of one kilometer of the road is, of course, the Shanghai Maglev - with a section length of 29.83 kilometers, the total construction cost was about 9.7 billion yuan (1 dollar = 6.2 yuan), and, accordingly, the cost per kilometer was 325 million yuan.
Well, the most expensive in terms of the total cost was, of course, the Beijing-Guangzhou high-speed highway project, which was put into operation gradually, by sections, and recently it opened up traffic from the destination to the destination. The total cost of 2,298 kilometers of roads was an astronomical sum of 400,000,000,000 yuan.
The cost of roads differs tenfold depending on the construction speed, the type of soil, the need for ramps and so on. Estimated cost per kilometer:
1) Qinhuangdao-Shenyang - 37,000,000 yuan per kilometer
2) Hefei Wuhan - 46,000,000 yuan per kilometer
3) Wenzhou-Fuzhou - 60,000,000 yuan per kilometer
4) Beijing-Shanghai - 167,000,000 yuan per kilometer
5) Beijing-Tianjin - 180,000,000 yuan per kilometer.
In general, as I understand it, it is unscientific to compare the cost of building railways with a maglev. There are dozens of railways, they were built in different conditions, and so far only one maglev is known and only the cost of the line is known in these conditions.
Nevertheless, the Shanghai Maglev project to Hangzhou was finally closed, and experiments to achieve high speeds using the traditional rail train clearly indicate that we will not see any other magnetic train lines in China in the near future.
And the planned increase in speed of up to 380 km \ h will make air travel over a distance of up to 1000 km unprofitable. The Beijing-Shanghai trip by plane takes about 4 hours (2 hours of net flight time + hour to / from the airport + hour for check-in / check-in / baggage claim, etc.), and by train - 5. Speed increase by 25% will equalize this time.
