When will Ning 'an Intercity Railway be opened to traffic?

Ning 'an Intercity Railway is a high-speed railway under construction from Nanjing, Jiangsu Province to Anqing, Anhui Province, with a total length of 257 kilometers, including 33 kilometers in Jiangsu Province and 225 kilometers in Anhui Province. The design speed is 25km/h, and the planned transportation capacity is 125 pairs of passenger trains per day. The total investment of the project is estimated to be 25.72 billion yuan, which is jointly funded by the Ministry of Railways, Jiangsu Province and Anhui Province. In July 213, the track laying began in Tongling-Chizhou section, which was completed in the first half of 215 and entered the joint debugging and testing stage, and the whole line was opened to traffic in July 215.

Ning 'an intercity railway is led from Nanjing South Railway Station, passes through Ma 'anshan East Station, Wuhu New Railway Station, Tongling Station and Chizhou Station, crosses Anqing Yangtze River Railway Bridge and reaches Anqing New Railway Station, with a total length of 257km and a design speed target of 25km/h. CRTSⅠ slab ballastless track slabs are adopted in most sections, and ballast ballast beds are adopted in some sections.

Ning 'an Intercity Railway can be connected with two railways, namely, connecting with Shanghai-Nanjing Intercity Railway through Xianning Railway in Nanjing to form a high-speed railway passage from Anqing to Shanghai, and connecting with Hefu Railway through tie lines in Tongling to form a high-speed railway passage from Anqing New Station to Hefei to Beijing.

Sites

Nanjing South Station ~ Jiangning South Station ~ Maanshan East Station ~ Dangtu East Station ~ Wuhu New Railway Station ~ Yijiang Station ~ Fanchang West Station ~ Zhongming North Station ~ Tongling Station ~ Maya Station ~ Chizhou Station ~ Yantang Station ~ Changfeng Station ~ Anqing New Station, in which Zhongming North Station, Changfeng Station and Yantang Station are reserved stations and will not be built in advance.

background

the newly-built railway in this project has a total length of 257 kilometers and a design speed of 25 kilometers per hour. The railway was jointly built by China Railway Corporation and Jiangsu and Anhui provinces, with a total investment of over 3 billion yuan.

On April 25th, 213, six stations, including Ning 'an Intercity Railway and Wuhu Station, were invited to bid online, namely Jiangning South Station, Maanshan East Station, Dangtu East Station, Wuhu Station, Yijiang Station and Fanchang West Station, and the underground corridor project jointly built with Wuhu City was also included. The construction period is 19 months. It will start on June 18th, 213, and meet the passenger demand on December 31st, 214. The Fangxi Square of Wuhu New Railway Station will end on June 3th, 215, which means that the Ning 'an Intercity Railway will be fully opened to traffic by July, 215 at the latest.

construction significance

this line directly attracts Nanjing, the capital of Jiangsu province, and Wanjiang, Anhui province, with dense population, active economy, precious land resources and strong passenger demand. Nanjing-Anqing is a busy traffic passage between Anhui, Jiangsu and Shanghai. The passage is mainly composed of Ningwu Copper Railway, tongling-jiujiang railway, national highways G25, G318 and Ningma Expressway, as well as Yangtze River shipping. In 27, the whole society completed 335.1 million tons of freight, including 6.23% by railway, 63.36% by road and 3.26% by water. The regional transportation structure is unreasonable. The existing Ningwu Railway is a single-track railway with low technical standards, small transportation capacity and low passenger car travel speed. The utilization rate of parallel running capacity has reached 97%, which can not meet the transportation needs. With the continuous growth of regional economy and the acceleration of economic and social integration, the links between cities along the railway line are getting closer and closer, and the passenger and freight volume will continue to increase. In 22 and 23, the passenger density in the largest section of the railway corridor will be 17.6 million and 26.43 million respectively, and the freight density will be 27.5 million tons and 35.8 million tons, so it is urgent to expand the transportation capacity of the corridor.

Jiuhua Middle Road Overpass (near the former fruit market) will be demolished and replaced by a railway bridge and culvert. The "high-speed corridor in the air" in Wuhu section of Ning 'an Railway, which passes through the main urban area, will soon rise from the ground. The design and construction scheme of Wuhu Railway Station, which is highly concerned by the public, has been revised and improved several times, and is awaiting the final approval of the Ministry of Railways. It is expected that construction will start in the second half of the year, and the scale will be increased from 5W to 6W square meters!

A number of control projects took the lead in making breakthroughs, and the Qingyijiang Railway Bridge was opened to traffic, and the extra-large bridge girder of Zhanghe River with a total length of more than 1 kilometers was coming to an end. Among the municipal projects involving railways, the reaming and reconstruction projects of the overpass at Tianmenshan Road and Beijing Middle Road (formerly Yingpanshan Road) have been carried out in an all-round way, laying the foundation for the rise of the "air high-speed corridor".

on August 28th, 211, it was a sultry day with sunny days and rainy days. The machines in the beam yard of Ning 'an Railway roared, cranes moved up and down, and transport vehicles shuttled back and forth. A bridge with a length of 32 meters and a weight of about 9 tons was finally built successfully through the cooperation of more than 2 technicians and constructors, including Qi Xin, and through nearly 2 processes such as steel bar cutting, formwork insertion, arrangement, binding, pouring and checking.
