For the railways under construction, everyone may be very concerned about their progress, after all, their progress is related to whether the line can be completed as planned, or even opened ahead of schedule. Before introducing the latest situation of the 18 railways under construction, I will first introduce to you what the construction of some railways includes, including the project construction and acceptance stage, which includes tunnels, roadbeds, bridges and other station front projects and station buildings, communications, signals, traction power supply and other station projects. The acceptance stage has to go through static acceptance, dynamic acceptance, preliminary acceptance, safety assessment, etc.
It is worth mentioning that the pre-station project starts before the post-station project, and the post-station project will generally start when the pre-station project is carried out to a certain extent. In addition, the professional engineering is not linear, and it does not mean that all tunnels, bridges, etc. will be laid after the completion of the tracks, and they will generally be carried out at the same time.
Therefore, you can judge the current state of these railways under construction according to the above railway engineering content, and the following mainly introduces the latest situation of 13 railways under construction.
Shenjiang Railway
Shenzhen-Jiangxi Railway: At present, the Shenzhen-Dongguan Tunnel (West Section) has entered the shield construction stage, and in terms of post-station engineering, Shenzhen Airport East Station, Marina Bay Station, Henglan Station, Zhongshan Station, Zhongshan North Station and related projects have started construction bidding, and it is planned to officially start construction in June this year and complete all by the end of October 2027.

At present, the scale of railways under construction in the mainland is still very large, and due to space limitations, this article will focus on the above 13 railways that have made new progress recently. For the progress of other routes, you can read the editor's past articles, and some future articles will also continue to pay attention to you!
