There may be two main intuitive impressions of a railway, one is the railroad track, and the other is the train, which basically together constitute our most direct and main memory of the railway. But they actually belong to different stages of a railway project, where the rails belong to the construction stage, which means that a railway is in a critical stage of construction, and if the train has been seen on the tracks, it means that the railway has at least reached the acceptance stage.
If the rails are already on the scene, will the trains be far away? This article mainly introduces the latest progress of track laying of 4 railways, of which 1 has just started, 3 have just completed track laying, and the following mainly introduces the specific situation of these 4 railways.
Yichang-Zhengwan high-speed rail line
Among them, the track-laying line from Yichang to Zhengwan has just started. The high-speed railway is located in Hubei Province, with a total length of 108 kilometers, and a total track mileage of 216 kilometers because it is a double line. It is understood that the high-speed railway is now advancing at an average speed of 6 kilometers per day, and according to this calculation, it will take about a month to complete the track laying.
The design speed of the line is 350 kilometers per hour, starting from Yichang East Station, and the whole line has Yichang East, Xiabaoping, Xingshan and other stations, which is part of the second phase of the "three-step" plan of the new high-speed rail channel along the Yangtze River in the mainland, that is, before the completion of the Yuyi high-speed railway with a design speed of 350 kilometers, the high-speed railway and the Zhengwan high-speed railway and the new Chongqing-Wanzhou high-speed railway form a high-standard high-speed rail channel from Yichang to Chongqing and Sichuan, and even from Shanghai to Chongqing and Sichuan. The Yuyi high-speed railway belongs to the third stage, when the Shanghai-Chongqing-Rong high-speed railway, the main line of the high-speed railway along the Yangtze River with a shorter path, will be truly completed, with a total line of 350 kilometers.
The high-speed railway is expected to be completed and opened to traffic next year, when the Hanyi railway, the Wuyi section of the Shanghai-Chongqing-Rong high-speed railway and the Zhengyu-Chongqing high-speed railway will be interconnected, and the travel time between Xingshan and Yichang will be greatly shortened.
Sichuan-Qingdao Railway Chengdu East to Huangshengguan Section
The three lines that have just completed the railway track laying are the Zhenjiangguan to Huangshengguan section of the Sichuan-Qingdao Railway, the Guangqing Intercity North Extension Line, and the Shanghai-Suzhou-Lake High-speed Railway.
Among them, the section from Zhenjiangguan to Huangshengguan of the Sichuan-Qingdao Railway failed to be opened together with the section from Qingbaijiang to Zhenjiangguan last year because the tunnel was not penetrated. After more than half a year of efforts, the section from Zhenjiang Pass to Huangshengguan has completed the track laying of the whole line before the end of the first half of the year, including 133.96 kilometers of track laying on the main line and 14.498 kilometers of track laying on the station line.
The total length of the line from Zhenjiangguan to Huangshengguan is about 148.458 kilometers, which is a national railway class I double-track railway, with a design speed of 200 kilometers per hour, and 4 stations including Huangshengguan, Huanglong Jiuzhai, Songpan and Zhenjiangguan. This section of the line is planned to be completed this year, which also means that the bullet train can go directly to Huanglong Jiuzhai within the year, which will greatly facilitate the railway travel along the line and drive regional economic development.
The northern extension of the Guangqing Intercity Railway
The Guangqing North Extension Line also completed the laying of the whole line of long track in the last month of the first half of this year. The total length of the project is 19.737 kilometers, the design speed is 200 kilometers / h, the line leads from the north end of Qingcheng Station of Guangqing Intercity Railway, to the end of the line, and there are 4 stations on the whole line: Yanhu New Town, Qingyuan East, Feixia Mountain (reserved) and Provincial Vocational Education City.
As an important part of the Pearl River Delta intercity railway, the northern extension of the Guangqing intercity railway can take the intercity train from the Jiangbei area of Qingyuan City to Guangzhou Baiyun International Airport after completion, which will further promote the further development of Qingyuan and the formation of Guangqing's "half-hour commuting circle".
The Shanghai-Suzhou-Lake high-speed railway, located in the Yangtze River Delta region, has also completed the track laying of the whole line before the second half of the year. The track-laying time of the high-speed railway lasted about 3 months, of which the fastest track laying in a single day was 12 kilometers in a single day in the ballastless track section and 2.5 kilometers in a single day in the ballasted track section.
Shanghai-Suzhou-Lake high-speed railway
The Shanghai-Suzhou-Lake high-speed railway has a total length of about 163.8 kilometers and a design speed of 350 kilometers per hour, and has 8 stations on the whole line, including Shanghai Hongqiao, Shanghai Songjiang, Liantang, Suzhou South, Shengze, Huzhou Nanxun, Huzhou East and Huzhou. It is expected that the static acceptance will begin in July this year, and it will be completed and opened to traffic by the end of the year. After completion, it can effectively relieve the transportation pressure of Shanghai-Nanjing and Shanghai-Hangzhou railway corridors, and greatly facilitate the railway traffic between Lishui, Liyang, Yixing and Shanghai.
Except for the Yichang-Zhengwan high-speed railway line, which is planned to be completed and opened to traffic next year, the other three are expected to be put into operation within the year. In fact, some of the railways that are planned to be completed and opened to traffic within this year have already been completed and opened to traffic, and the remaining lines have already entered the acceptance stage, and there are not many railways that are still in the track-laying stage.
Probably only the extension line of Kaifeng Station of Zhengkai Intercity Railway, Jidayuan High-speed Railway, and Nanyu Intercity Railway are left, and the rest are either in static acceptance, or in joint commissioning and testing, or have entered the trial operation stage.
