The background is: the dispute between the MRT era and the Shanghai-Kunming high-speed railway, and the overall improvement of the thinking of the Ministry of Railways (Chongqing-Guizhou Railway and Changbai Railway have similar problems). China Railway Construction entered a vigorous era before the Lou-Shao double-track project started. The Beijing-Guangzhou Railway and the Hunan-Guizhou Railway were built only a few years ago, and then the Beijing-Guangzhou high-speed railway and the Shanghai-Kunming high-speed railway were built. As a new thing, China's high-speed railway and express railway suddenly blossom everywhere (rapid development), and Loushao double-track project has fallen far behind the times (there are many similar situations in China), especially the direction of Shanghai-Kunming high-speed railway line has caused controversy. Shaoyang felt like a dead port of traffic, which became relatively backward in the high-speed era. The fierce competition between Shaoyang City and some counties and cities in Loudi City became a rare phenomenon in China at that time, which led to the improvement of railway construction ideas in Hunan Province: the Shanghai-Kunming high-speed railway was only Shaoyang City, however, the Loushao railway construction project was upgraded (the other two regional development projects that were partially compensated were the construction of Huaishaoheng Railway and the construction of Shao Ping Expressway connecting the high-speed railway to Shaoyang North Station), which led to The original capacity expansion and reconstruction project was to build a double track, and later a new railway was built, although it can also be said that a new line was built. More than 90% of the newly-built roads are far away from the old roads: in 2009-20 15, a new Lou-Shao railway was built under the old name of capacity expansion and transformation. More than 90% of the new routes are far from the old ones. 1) Loudi area, using the south station in Loudi city, almost all new roads are far from the old roads. The tea garden section, Shuangbanqiao section, Hongshan Temple section, Jinzhai section, Santangpu section and Jinxingpu section on the Laoloushao Railway are all abandoned in the construction of new roads, and the new railways are all built in distant places; 2) In Shaoyang area, most new roads are far away from the old roads, which can be described as abandoning some old roads in Lianqiao section (the cost of new double-track roads is lower than that of rebuilding old roads in rocky mountainous areas), some detours from Lianqiao town to Shaodong county, Niumashi section and Fanjiashan section (because coal mined-out areas are avoided), and the old roads in Shaoyang city, that is, the front and rear sections of Shuangqing Station (formerly Shaoyang North Station) (because the old roads divide the city from the middle).
A few new roads are close to the old ones: Loudi area, only in an old place near Shuanglian Station (belonging to Hongshandian Town, with a highway connecting Shuangfeng County), the new road is close to the old road, but a new railway has been built, and a railway station has been built at the new site, called Shuangfeng North Station (the Anzhangheng Railway has Shuangfeng Station via Yongfeng Town of Shuangfeng County); In Shaoyang area, only the old Lianqiao Station, Shaodong County and Shaoyang City are near the old roads, but all the newly built roads are near the new railways (instead of rebuilding the old roads for new use), and Lianqiao Railway Station and Shaodong Railway Station have also been built.
Reasons for new construction: the so-called expansion and reconstruction can only reflect the original intention of the project, but it was later changed to be unworthy of the name. In fact, a new railway was built, not an old road. The reporter reported that Chen Gongchun, director of Shaoyang Airport Office, also said that "the Loushao Railway expansion project is equivalent to rebuilding a railway". The reason for the new Loushao Railway is that the old road is very poor, and it is necessary to maintain the operation of Luozhan Railway, while the new road is a two-lane express railway with a speed of 200 kilometers per hour. It is difficult to rebuild the old road, and it is impossible to stop using the old road for many years, so we can only rebuild the furnace and repair the new road, just like building a new Beijing-Guangzhou railway near the old Beijing-Guangzhou railway and turning it into a Beijing-Guangzhou high-speed railway. Loudi, Loudi West Station, Shuangfeng North Station, Lianqiao Railway Station, Shaodong Railway Station (the original Shaodong Station was renamed Dahetang Station), Shaoyang East Station and Shaoyang Railway Station.
Take the ordinary railway at Loudi to Loudi Railway Station, and take the Shanghai-Kunming high-speed railway to Loudi South Station through the connecting line.
Shuangfeng North Station is near Shuanglian Station of Laoloushao Railway. In Hongshandian Town, there is a highway connecting Yongfeng Town of Shuangfeng County, and the Anzhangheng Railway under construction has set up Shuangfeng Station in Shuangfeng County. Lianqiao Town is one of the top ten medicinal materials markets in China. Under the high wall in the south of the medicinal materials market is the new railway station. The most developed area in Shaoyang is Dongcheng District. From Shaoyang to Changsha by train: 48 minutes to Loudi South Station; Loudi South Station takes the Shanghai-Kunming high-speed railway for 80 minutes, and Loudi Railway Station takes the Hunan-Guizhou Railway for 200 minutes.
The new Loushao Railway has made Shaoyang City in the era of high-speed rail-fast rail a convenient passage to the northeast and east. Comparing the national situation: high-speed rail and fast rail are blooming everywhere. At the press conference of the State Council Office in February, 20 15, Mr. Tie said that by the end of 20 15, the operating mileage of China's high-speed railways would be18,000 kilometers, and the high-speed railways would reach more than 40,000 kilometers (total railway mileage12,000 kilometers). There are dozens of high-speed trains near the so-called Shaoyang North Station, which is only a remote area in the north of Shaoyang.
After completion, the transportation capacity of Loudi-Shaoyang railway will be greatly improved, with the daily number of passenger trains increasing from 8 pairs to 20 pairs, and the annual freight capacity increasing from190,000 tons to 34 million tons. On 20/200915, a new express railway line was built. The total length is 93 kilometers, with two lines and a speed of 200 kilometers per hour. The reserved maximum speed can reach 250km/h. Passenger and freight are on the same line (freight is mainly used at night), and electric traction is adopted.
As early as June 5438+February 2004, the Ministry of Railways and the provincial government included the capacity expansion and reconstruction project of Loushao Railway in the 11th Five-Year Plan. In September 2005, the Ministry of Railways organized a pre-feasibility study review of the project. On August 18, 2008, the Ministry of Railways organized a pre-feasibility study review meeting for the capacity expansion and reconstruction project of Loushao Railway in Beijing. The Ministry of Railways and the provincial government have determined that the capacity expansion and reconstruction of Loushao Railway shall be carried out in accordance with the overall requirements of Luozhan Passage, and shall be jointly examined and approved by the Ministry of Railways and Hunan Province. The project establishment and feasibility study were completed in 2008, and construction started in 2009.
According to reports, the capacity expansion and reconstruction project of Loushao Railway is built according to the national first-class railway standard of double-track electrification, with a speed of 200 kilometers per hour, passenger and cargo are on the same line, and electric traction is implemented (the capacity is 4,000 tons of trucks, 20 pairs of buses and 42 pairs of flat planning capacity), and EMU is considered. The line starts from the center of Loudi Station and ends at Shaoyang North Station, with a total length of 93.2798km. The total investment of the project is about 7.5 billion yuan, and the construction period is 3 years, including 47 km in Shaoyang. It is planned to be completed and put into operation in 20 12. After the capacity expansion and reconstruction project of Loushao Railway is completed, the original 13 station will be transformed into seven stations: Loudi, Loudi West, Shuangfeng, Lianqiao, Shaodong, Shaoyangdong and Shaoyang. After the completion of capacity expansion and transformation, the passenger train speed of Loushao Railway will reach 200 kilometers per hour, and citizens can take the train from Loudi to Shaoyang, which can save 3/4 of the original time.
On February 25th, 2008, at 65438, the newly-built line of Fanjiashan-Shaoyang North Section was moved 3.8km south, Shaodong Railway Station was moved 3.3km south, and the length was 15.4km, so the new line was moved south to avoid it. The original line from Niumashi to Fanjiashan passed through the goaf of Niumashi Coal Mine, and the new line moved northward to Nanchong. Maximum design speed of passenger train 160km/h: from Shuangfeng to Lianqiao, the original line in Shaoyang passes through Jinxingpu, and the number of main lines is single-track reserved double-track, with an investment of 65.438+88.5 million yuan; The railway grade is Grade I, of which 48.7 kilometers are in Shaoyang, with an investment of 3.82 billion yuan. The recommended reconstruction plan is: the reconstruction mileage is 98.679 kilometers, and the Ministry of Railways and the Hunan Provincial People's Government immediately plan to hold a mobilization meeting for the expansion and reconstruction of the Loudi-Shaoyang railway.
In September, 2008, China Railway No.4 Survey and Design Institute submitted the feasibility study report of the technical transformation project from Loudi to Shaoyang North of Loushao Line to the Ministry of Railways. After the feasibility study review meeting, in order to fulfill the original promise and appease the anxiety of Shaoyang people, the feasibility study was approved and put into trial operation on June 29, 2009. At the same time, the Shaoyang-Yongzhou section of the Luoyang-Zhanjiang railway passage has also been completed.
In 2008, the Hunan provincial government announced that the capacity expansion and reconstruction project of Loushao Railway started on June 1 2009.
Yiyang-Loudi section of Luoyang-Zhanjiang railway passage1999 65438+completed in February; From June, 5438 to February, 2000, according to the Notice of the State Planning Commission on Issuing the Eleventh Batch of Newly Started Large-scale Capital Construction Projects in 2000 (No.2250), the project started. On June 30, 2003, the track laying of the main line of the whole line was completed, and the preliminary design was not completed. However, the environmental impact report has not been publicized and approved, and it is required to speed up the preliminary work such as project establishment.
Although the groundbreaking ceremony announced the commencement of the reconstruction of Loushao Railway, our city sent personnel to attend, and the Ministry of Railways organized a pre-feasibility study review meeting of Loushao Railway capacity expansion and reconstruction project in Beijing, and agreed to include Loushao Railway capacity expansion and reconstruction project in the new construction project in 2009. On August 18, talks were held with the provincial government on speeding up the railway construction in Hunan. Lu Dongfu, Vice Minister of the Ministry of Railways, and his party came to Changsha and received the attention and support of the leaders of the Ministry of Railways. Compare the railway mode. On July 30th, 2008, it means that the capacity expansion and transformation of Loushao Railway really started.
At the initiative of the municipal party Committee and the municipal government, the construction unit will officially enter the site. After the bid opening, the tender will be held in the Engineering Trading Center of the Ministry of Railways. The Engineering Appraisal Center of the Ministry of Railways will approve the preliminary design, and the preliminary design review meeting of Loudi-Shaoyang railway capacity expansion and transformation will be held in Beijing. After the review meeting, the traffic requirements can be met within five years. Huaishaoheng express railway, like Huaishaoheng express railway, was included in the column of express railway in the Twelfth Five-Year Comprehensive Transportation System Plan in March 20 12.
Name problem: The official media of the capacity expansion and reconstruction projects of Changbai Railway and Chongqing-Guizhou Railway often say that they are Changbai Express Railway and Chongqing-Guizhou Express Railway, while similar projects of Loushao Railway and Jinwen Railway rarely use such names, only adding a new word. Many medium-sized railways in Northeast China use the name of express railway, while express railways such as Huaishaoheng Railway in Hunan rarely use the name of express railway. Only Yuchangxia Railway is named Yuchangxia Express Railway. In fact, the name of express railway can also be used to distinguish it from the traditional ordinary railway. The new line of Loushao Railway is Loushao Express Railway (hereinafter referred to as Loushao Express Railway). Loushao express railway was opened on October 6th, 2006/KLOC-0+65438. This van is an ordinary train. There are two types of buses: the previous Japanese buses 16 pairs; 9 pairs of ordinary trains take the Luozhan line and Xiang Qian line; 7 pairs of G-prefix high-speed EMU trains take Shanghai-Kunming high-speed railway and Beijing-Guangzhou high-speed railway, and can only travel fast on Lou-Shao line.
Because the section of Loushao Express Railway is very short, other trains between Loudi and Shaoyang can meet the passenger demand, and there is no special D-prefix train between Loushao and Shaoyang. Railway grade: National Railway Class I..
