According to the railway planning and construction process, the pre-feasibility study review of the railway project invested by the state can directly enter the feasibility study stage after obtaining the review opinions of the China Railway Group. The main work content of the pre-feasibility study includes the bidding of the survey and design unit, the preparation and review of the pre-feasibility study report, etc.
In the past two years, the "14th Five-Year Plan" key railway projects in the mainland have launched the survey and design bidding of many lines, and officially started the preliminary work of the project, but most of them have completed the pre-feasibility study and preparation, but they have not passed the review of the China Railway Group. Overall, there are currently 2 railways that have completed the pre-feasibility study review and officially entered the project feasibility study stage, including 1 high-speed railway and 1 ordinary railway.
Wenfu high-speed railway
One of the high-speed rail projects is the Wenfu high-speed railway, which is an important component of the Ningbo-Guangzhou high-speed railway (Ningbo-Guangzhou), which is a corridor with a design speed of 350 kilometers per hour. In fact, the Ningbo-Guangzhou high-speed railway is also the name of a high-speed rail channel newly named in the past two years, which is essentially a part of the coastal corridor and an upgraded version of the existing coastal railway.
The Ningbo-Guangzhou high-speed railway is actually composed of multiple sections, such as the Zhangshan high-speed railway, the Guangzhou-Shantou high-speed railway, and the Wenfu high-speed railway, which belongs to the Wenzhou-Fuzhou section. Compared with the existing Wenfu railway between Wenzhou and Fuzhou, the new Wenfu high-speed railway has a design speed of 350 kilometers per hour, and the pre-feasibility study recommendation plan shows that the whole line plans to set up 11 stations such as Wenzhou East, Ruian East, Pingyang, Cangnan, Fuding West, Zherong, Fu'an South, Ningde, Luoyuan, Lianjiang and Fuzhou South, with a total length of about 279 kilometers.
In the section of the Ningbo-Guangzhou high-speed railway corridor that has not yet started, the progress of the Wenfu high-speed railway is relatively fast, because the new Ningbo-Wenzhou high-speed railway in the Ningbo-Wenzhou section has not officially started the preliminary work of the project.
And compared with the railway that started the project survey and design work at the same time, the progress of the Wenfu high-speed railway is also fast. With the approval of the pre-feasibility study of the project, the whole line of Wenfu high-speed railway has officially entered the preliminary stage of feasibility study, and is expected to officially start construction by the end of 2025. After the completion of the line, the travel time between the two places will be shortened by about 30 minutes.
Wenshan-Jingxi Railway
The other ordinary railway is the Wenshan-Jingxi section of the Yunnan-Guizhou border railway. The line starts from Wenshan Station of Mongolian-Wenwen Railway, sets up a station on the east side of Yanshan County, and sets up Funing Station in parallel with Yunnan-Guizhou Railway, and then sets up a station through Napo to connect to Jingxi Railway Jingxi (Avenue Station), and then uses Tianjing Railway Expansion and Reconstruction Project to Tiandong Station to connect to Nankun Railway.
As a section of the "Monkey Bridge to Fangchenggang Border Railway (Yunnan Section)", the railway is an important part of the transverse channel, and the railway from Tiandong to Jingxi in the region has been completed. The technical standard of the section from Wenshan to Jingxi is the first class of the national railway, with a design speed of 160km/h single-track electrified railway, with a total length of 265.874km, including 193.16km in Yunnan and 72.714km in Guangxi, with a total of 23 stations and a planned construction period of 4.5 years.
At present, the railway has officially entered the feasibility study report preparation stage, and it is expected to officially start construction in the next two years. After completion, it can promote passenger and freight exchanges between the southwest region and the Pan-Pearl River Delta and the Yangtze River Delta region, and connect the Kunhe, Nankun, Yunnan-Guizhou and other railway trunk lines.
China High-Speed Rail
Written at the end: the pre-feasibility study stage is mainly to conduct preliminary research on the functional positioning, passenger and freight volume, construction standards, route direction and station setting of the project, etc., mainly to demonstrate the necessity, possibility and risk of the project. Judging from these contents, pre-feasibility studies are actually similar to feasibility studies. The facts are similar, but the level of detail is different, with the depth of the pre-feasibility study being shallow and the feasibility study being deep.
From the perspective of the entire railway project cycle, from the pre-feasibility study review to the final project construction bidding and start-up, the time is about 2-3 years. Therefore, if the Wenfu high-speed railway and the Wenshan-Jingxi railway are carried out smoothly, it is expected that the construction will officially start in the near future, that is, within these two years.
As for the railways that launched the survey and design bidding at the same time as the two railway projects, it remains to be seen whether the construction can start in the next two years because the pre-feasibility study of the project is still waiting for review.
