provinces are striving for the "inter provincial" railway to start construction in the last year of the 13th five year plan or even the 12th Five Year Plan to appear in batches. Experts who participated in relevant discussions told the author that the ideas of the 13th five year railway plan draft, which has been conducting research since the middle of the year, may include high-speed rail between provincial capitals, and even inter provincial lines with a speed of at least 250 kilometers per hour can speed up transportation. The utilization of joint plastic has exceeded 50% of the total amount of food packaging materials

for example, Changsha to Xi'an, Chongqing to Xi'an, Zhengzhou to Jinan, Zhengzhou to Hefei (through Zhoukou), Guiyang to Nanning, Wuhan to Hangzhou, Hefei to Nanchang, Ganzhou to Shenzhen and other high-speed rail lines have been planned by local governments

Guiyang, the capital of Guizhou Province, is a typical case. In addition to accelerating the construction of lines to Kunming, Changsha and Chongqing, we are also striving to start the construction of lines to Nanning and Zhengzhou as soon as possible

Guiyang Guangzhou high speed railway (Guiyang Guangzhou) will be officially put into operation on December 20. The space-time distance between Guiyang and Guangzhou with other sensors in the past 20 hours will be reduced to 4 hours

it is learned that at present, the local government is "jointly striving for the Guiyang Nanning express railway to be incorporated into the national '13th five year plan' for organization and implementation." Chen miner, governor of Guizhou Province, said at the Pan Pearl River Delta cooperation and development high level Forum on October 12

in addition, the local government is also preparing to strive for the Guiyang Zhengzhou high-speed railway to be included in the 13th five year plan. In addition, the province also hopes to start construction of six railways including Panzhihua Zhaotong Qianjiang during the 13th Five Year Plan period

it is learned that this is directly related to the early thinking of the current national 13th five year railway planning. Informed experts participating in the discussion pointed out that the idea of the draft 13th five year railway plan may include that all provincial capitals will be connected by high-speed rail, and inter provincial railways can be connected by high-speed rail. At the same time, the speed of the previous inter provincial railways is in principle more than 250 kilometers per hour, in order to solve the problem of cross line railway compatibility in the future

affected by this, the newly planned high-speed rail may increase by tens of thousands of kilometers during the "13th five year plan". The 2020 planning target adjusted in 2008, that is, the target of 120000 kilometers of railway and 16000 kilometers of high-speed rail in 2020, is expected to be completed ahead of schedule in 2015 at the end of the 12th Five Year Plan

Dong Yan of the Comprehensive Transportation Research Institute of the national development and Reform Commission said that it is necessary for all regions to plan a large number of high-speed railways. Since the opening of the Beijing Shanghai and Beijing Guangzhou high-speed railways, the occupancy rate has been rising, and the passenger flow has increased rapidly, which has led to the rapid development of tourism and other economies along the railway, and the rapid appreciation of land, which is much more than expected

"now local governments have seen that high-speed rail has a great impact on the local economy and is highly motivated. It is better to build new lines than to transform the old lines, because it is conducive to building cities, and there is no shortage of funds for railway construction." He said

"13th five year plan" high-speed rail boom

at present, Beijing Shanghai, Beijing Guangzhou, Shanghai Shenzhen, Shanghai Hanrong, Daxi (Datong to Xi'an), Zhengzhou Xi'an (Zhengzhou to Xi'an), Shenyang Dalian and other high-speed railways have been opened nationwide

Guiguang (from Guiyang to Guangzhou), Lanxin (from Lanzhou to Urumqi) and Guiguang (from Guangzhou to Nanning) have been completed and will be officially opened to traffic this year. In addition, the Changsha Kunming section of Shanghai Kunming high-speed railway will be opened to traffic next year. Other high-speed railways such as Beijing Shenyang and Beijing Zhangjiakou are under construction. The newly built railway this year is about 56000 kilometers. According to this, the distance of high-speed railway at the end of this year is followed by buildings, which are expected to reach about 16000 kilometers. Thus, the 2020 high-speed railway planning goal adjusted in 2008 is expected to be achieved ahead of schedule

Hubei Province hopes to start construction of the high-speed railway from Wuhan to Xi'an in 2015, the last year of the 12th Five Year Plan. A person from the transportation department of the Shiyan development and Reform Commission told the author that Shiyan City hopes that the high-speed railway from Wuhan to Xi'an will reach a speed of 350 kilometers per hour. At present, it is reporting to Hubei Province and striving for it, "in the end, it is hard to say how. But it should be no problem to start construction during the 13th Five Year Plan period."

in the west, in addition to the high-speed railway from Guizhou to Nanning mentioned by the governor of Guizhou Province Chen miner in his public speech, Guizhou also expects the high-speed railway from Guiyang to Zhengzhou to start construction during the 13th Five Year Plan period

according to the news from Zunyi government department station on October 14, in the "13th five year plan" railway development plan proposal of Guizhou Province, there are four projects that have been included in the national "13th five year plan" railway planning, including one involving Zunyi City, namely Panzhihua Zhaozhou Guizhou Railway (passing through Renhuai City, Zunyi County, central urban area, Suiyang County, Meitan County, Fenggang county)

Guizhou is striving for six lines to be included in the 13th five year plan, including Guiyang Zhengzhou Passenger Dedicated Line (passing through Yuqing county and Meitan county), Fuling Liuzhou Railway (passing through Daozhen Autonomous County, Zheng'an County, Wuchuan Autonomous County and Yuqing county), Luzhou Zunyi Railway (passing through Chishui City, Xishui County and Renhuai City), etc

in this regard, Wang Mengshu, an academician of the Chinese Academy of engineering, pointed out that during the 13th Five Year Plan period, all the railways that can be built across provinces to connect the provincial capital cities should be built, and the lines from all provinces to Beijing should strive for high-speed railways, and the speed should be higher

it is understood that the lines between many provincial capitals have long been the content of the 12th Five Year Plan in the province. For example, Zhengzhou Taiyuan high-speed railway and the line from Zhengzhou to Jiaozuo have started, but the section from Jiaozuo to Taiyuan has not yet started. Similarly, Chongqing has already started construction of the railway to Wanzhou, but the planning of the Zhengzhou Chongqing Railway (Chongqing Wanzhou Xiangyang Zhengzhou) has just been approved

railway grade needs to be improved

interestingly, at present, many provinces are preparing to include new lines in the national "13th five year plan", and the grade needs to be improved

Wang Mengshu, an academician of the Chinese Academy of engineering, pointed out that the best speed for the construction of high-speed rail adjacent to the provincial capital cities is more than 250 kilometers, and it is better to strive for higher speed. 350 km/h or 250 km/h is OK. The high-speed railway from Chengdu to Kunming in the West may not be so high due to the terrain, but you can also strive for a speed of more than 250 km/h

this year's railway planning investment is 800billion, and now there is still about 500billion to be completed. "Many provincial capital cities will build high-speed railways sooner or later, but there are priorities, to see if there is money." He told the author

according to the National Bureau of statistics, the monthly railway investment this year was 335.5 billion yuan, an increase of 20.6% year-on-year. But there is still a gap from the goal of 800billion

it is understood that the above-mentioned high-speed railway from Changsha to Xi'an is actually an improvement of the an Zhang Heng line (Ankang Enshi Zhangjiakou Hengyang), connecting multiple lines in series

Tong Ming, deputy director of the Hunan Provincial Development and Reform Commission, pointed out in September this year that Hunan is striving to bring more projects such as the Chang Yi Chang railway, Changsha Xi'an high-speed railway, Changde Guilin Haikou, Yueshan Yiyang, Xiushan Yiyang into the 13th five year plan and the national medium and long-term plan

Chang Yi Chang (Changsha Yiyang Changde) is connected with Qian Zhang Chang (Chongqing Qianjiang Zhangjiajie (8.32, 0.01, 0.12%) - Changde), and the Ankang Enshi Zhangjiajie line is also a national research line. In this way, from Xi'an to Changsha, we can rely on the Xi'an Ankang Enshi Zhangjiajie Changde Changsha line

Li Yuhui, chief of the comprehensive section of Hubei Enshi Prefecture railway office, told the author that Hubei is indeed striving for the Ankang Enshi Zhangjiajie Hengyang Railway to be included in the national 13th five year plan, and the current speed is only kilometers per hour. "It's better to be faster." He said

many places are also striving for upgrading on the basis of existing lines. For example, Jiangxi and Anhui hope to build the high-speed railway from Hefei to Nanchang. The two places hope to start construction during the 13th Five Year Plan period, including Anqing and Jiujiang, which will be built by Intercity Railway first. At present, there is an express railway from Jiujiang to Nanchang with a speed of about 200 kilometers per hour. Jiangxi hopes to rebuild a high-speed railway with a speed of 350 kilometers per hour from Jiujiang to Nanchang. At the same time, the high-speed railway from Nanchang to Ganzhou, namely the Beijing Kowloon line, is also designed to reach a speed of more than 350 kilometers per hour

in fact, the current high-speed railway from Wuhan to Xi'an and the Wuhan Shiyan section of Hubei Province, which was started in advance, also exist in the form of intercity railway. Similarly, the high-speed railway from Wuhan to Hangzhou passes through Anqing. Hubei hopes that these lines will be incorporated into the 13th five year plan

Zhang Jiangyu believes that the Beijing Kowloon Railway, as the national north-south trunk line, should reach the standard of 350 kilometers per hour. However, in many intercity railways, PMMA is widely used as intraocular lens transplantation material in surgery, but its contact with corneal epithelial cells will cause permanent damage to corneal epithelial cells, which does not meet this standard. The speed is only 200 kilometers per hour, which needs to be improved; Otherwise, there will be compatibility problems between railways in the future

however, some people are worried. A person from the transportation department of the development and Reform Commission of a western province told the author that, for example, Xi'an to Chongqing strive to start construction in the 13th five year plan. Now the feasibility study report has not been released, and it is hard to say what will happen in the end

Dong Yan pointed out that after the reconstruction of the old railway, it can also reach the level of 200 kilometers per hour, but it is not as good as the new line after all, because after the new passenger dedicated line is built, new towns can be built around the railway, and the original railway can be used for freight transportation. "Therefore, it is generally better to rebuild the old railway than to build a new railway, and local governments have great enthusiasm for building a new railway."
