In Northeast China, there are four high-speed railways, including the Qihai section of the Qihai-Manchurian high-speed railway, the Mudun high-speed railway, the Changliaotong high-speed railway, and the Harbin-Tieli section of the Hai-Iran high-speed railway.
The remaining three high-speed railways are included in the planning, except for the Qihai section of the Qihai-Manchurian high-speed railway, which is a planning and research project, and the remaining Mudun high-speed railway and Changliaotong high-speed railway, which have not yet started, were originally planned to start construction during the "14th Five-Year Plan" period. However, after the promotion of the "14th Five-Year Plan" in the first few years, these two lines have not been promoted ideally.

In contrast, the progress of the Changliaotong high-speed railway is relatively better than that of the Mudun high-speed railway, because at least in the past few years, the China Railway Group has officially launched the survey and design of the high-speed railway, so it has also become the first high-speed rail project in Northeast China to officially start preliminary work during the "14th Five-Year Plan" period.
Therefore, since the China Railway Group officially launched the preliminary work of the project last year, the Northeast region is also full of expectations for the start of the Changliaotong high-speed railway, and the Changliaotong has become the most promising high-speed rail in the remaining two years during the "14th Five-Year Plan" period in the Northeast region. However, from the current point of view, it is not so easy to start construction of the high-speed railway.
Because, judging from Jilin Province's reply to "when will the Changliaotong high-speed railway start" this month, the high-speed rail will start construction in the near future is not so optimistic. The reply mentioned that "the Changliaotong high-speed railway is a cross-provincial project, and the line is long and large-scale, involving complex and numerous preliminary work, and a large amount of survey and design workload, and there are many factors that need to be considered in the overall arrangement of the preliminary work of the national railway project, and the preliminary work of the project requires a certain period." ”
Judging from the reply, it is mentioned that "the Changliaotong high-speed railway is a cross-provincial project" is worth thinking about, because the high-speed rail in the "13th Five-Year Plan" railway planning, is from Siping Station on the Beijing-Harbin line, planning the line to Tonghua high-speed rail, but since the start of the project survey and design in the past two years, the lines discussed by everyone are from Changchun City, directly to the south of the new line through Shuangyang District, Yitong, Liaoyuan, Meihekou, Liuhe, and finally to the end of Tonghua City. The total length of the whole line is about 280 kilometers, the planned operating speed is 350 kilometers per hour, and there are 7 stations along the line, including Changchun West Station, Yitong Station, Liaoyuan Station, Dongfeng Station, Meihekou Station, Liuhe Station and Tonghua West Station.

If you talk about the current line, it is all in Jilin Province and does not belong to the inter-provincial line. The only thing that can be further explained is that the project also plans to build a liaison line from Siping to Liaoyuan at the same time, and this liaison line will pass through Xifeng County, Liaoning Province, so it is an inter-provincial project, so this may also be a reason for the start of the high-speed railway.
In addition to the complicated preliminary work caused by the impact of the line plan, the reply mentioned that "there are many factors that need to be considered by the China Railway Group in the overall arrangement of the preliminary work of the national railway project" are also worth paying attention to. According to the editor, this sentence reveals more about the priority of high-speed rail construction.
From the point of view of line positioning, the Changliaotong high-speed railway belongs to the inter-provincial channel and regional connection line of high-speed rail, and the focus of the mainland high-speed rail during the "14th Five-Year Plan" period is to run through the main channel of the "eight vertical and eight horizontal" high-speed rail, from the three high-speed rail lines approved in the past few months this year, the Yuyi high-speed railway, Jiaoluoping high-speed rail are part of the main channel of the mainland high-speed railway, and although the approved Tongji railway is also a regional high-speed rail connection line, but after all, the preliminary work of this railway has been promoted for more than ten years, and the conditions for feasibility study approval have been mature.
On the other hand, the Changliaotong high-speed railway, the line positioning is not the main channel of the high-speed railway, from the perspective of the official start of the preliminary work at the national level, the Jiaoluoping high-speed railway is in 2022, and the Changliaotong high-speed railway is in 2023, and the progress is relatively late.
Changliaotong high-speed railway and Siping liaison line
At present, the Changliaotong high-speed railway is still advancing the survey and design work, according to the current progress, it is already very difficult to start construction during the "14th Five-Year Plan" period, perhaps until the beginning of the "15th Five-Year Plan".
For the Northeast region, the progress of the Changliaotong high-speed railway, which is the most promising to start construction in the near future, is not ideal, so can the Mudun high-speed railway become the baton? Judging from the current situation, it is still far from the construction of the Mudun high-speed railway, and there is basically no major progress in the preliminary work of the project.
As an important part of the Shenyang to Jiamusi high-speed rail line, but also the last section that has not started, Mudun high-speed rail has not been promoted by any substantive projects, if you want to see the start of construction, it seems that you should first pin your hopes on the Changliaotong high-speed railway.
