If each railway wants to enter the implementation stage, in addition to being included in the plan, it must first obtain feasibility study approval, which determines whether the project is allowed to be built, and secondly, it must complete the design approval, including preliminary design and construction drawing design, which is the technical basis for the railway to start construction smoothly.
Take the feasibility study approval as an example, according to the importance of the project and the funding situation, the subject of the approval is completely different. For example, the railways invested by each province can be approved by themselves. However, if the railways in the province are funded by the state, it is the joint approval of the national railway group and the provinces. There are also some railways that are inter-provincial and inter-regional, or those that are mainly funded by the state and are approved by the National Development and Reform Commission.
High-speed rail trains
Among the key projects planned to start this year, most of them actually belong to inter-provincial railways, but a few of them belong to pure intra-provincial railways, to be precise, pure intra-provincial high-speed railways, because most of them belong to high-speed railways, and ordinary railways account for a very small proportion. According to the statistics of the editor, there are about 5 pure intra-provincial railways planned to start construction this year, of which 4 are high-speed railways or intercity railways, and 1 is a general-speed railway. And judging from the latest progress, only one has approved the feasibility study and preliminary design.
First of all, among the five railways, the only railway that has approved the feasibility study and preliminary design - the Mianyang to Suining section of the Miansui Inner Railway. The total investment of the project is expected to be 32.852 billion yuan, of which 4.566 billion yuan will be borne by Mianyang City, 3.483 billion yuan by Suining City, and the remaining 8.377 billion yuan will be raised by Shudao Group.
At present, the Miansui Railway is not only the fastest among the five provincial railways planned to start, but also the fastest even if it is put into the national railway projects that are planned to start. At present, the construction drawing review has been carried out, and it can be said that the construction bidding will be hung up and enter the stage of full construction.
Bomi to Ranwu Railway
Secondly, let's look at the general-speed railway project that is expected to start this year, which is the Bomi to Ranwu section of the Yunnan-Tibet Railway. This section of the railway is completely located in Nyingchi City and Changdu City, Tibet, with a total length of 134.47km on the new main line of the project, leading from the Chengdu end of the proposed Bomi Station, passing through Songzong Town and Yupu Township of Bomi County to Ranwu Town of Basu County along the way, reserving the conditions for further extension to the east.
The Bomi to Ranwu section is an important component of the Bomi to Shangri-La section of the Yunnan-Tibet Railway, which is owned by the Sichuan-Tibet Railway Co., Ltd. and is funded by the state. China Railway Group officially launched the survey and design work of the project in 2022, and the feasibility study of the project has been submitted for approval, and the preliminary design related work is also advancing simultaneously, and the environmental impact assessment of the project has also been started.
The Jiaoluoping high-speed railway in Henan Province has been reported that it has obtained feasibility study approval, but there is no authoritative news to confirm it. The high-speed railway is an important part of the Hunan Corridor and belongs to the trunk line, and the trunk railway is played by the China Railway Group, which will also be funded, and the feasibility study of the project will be jointly approved by the China Railway Group and Henan Province. At present, the high-speed railway has been in the preliminary work of speeding up the preliminary design approval, land group and land acquisition and demolition, and is a key project planned to start construction in Henan this year.
Therefore, whether it is from the importance of the high-speed railway in the mainland road network, or the importance of the province of Henan Province, as well as the current progress of the project, the Jiaoluoping high-speed railway is likely to start construction this year, but the start time may need to wait until the end of the year.
Xiong'an Station
There is also the Shixiong Intercity Railway in Hebei Province, which was shelved a few years ago, and the preliminary work has only been restarted in the past two years, and the project is progressing well. China Railway Group has conducted a feasibility study review, and the pre-examination of the land has also been approved, and the preliminary design stage is also being fully determined. The project land involves Lianchi District, Qingyuan District, Lixian County, Boye County, Anguo City, Dingzhou City and Shijiazhuang Chang'an District, Luancheng District, Gaocheng District, Wuji County and Zhengding County of Baoding City, Hebei Province, with a design speed of 350 km/h.
The railway is implemented by the Beijing-Tianjin-Hebei Intercity Railway Company, which is controlled by China Railway Group, and the project is currently in the stage of feasibility study and preliminary design approval.
Wuwei to Zhangye section of the railway
Finally, it is the Wuwei to Zhangye section of the Lanzhang 34-line railway, which is a high-speed railway in Gansu Province and belongs to the last section of the Lanzhang 34-line railway that has not been started. In fact, the feasibility study and preliminary design of the section from Wuwei to Zhangye have entered the review stage, of which the feasibility study is already in the process of promoting approval, and the construction drawing design work is also advancing.
The high-speed railway, together with the Shanghai-Zhai-Hangzhou Railway and the Wenfu High-speed Railway, will officially start the project survey work by the China Railway Group in 2022, while the other two lines are basically in the early stage of feasibility study, but the Wuwei to Zhangye section is already in the process of promoting approval and plans to start construction this year.
