Project Planning of Xiangpu Railway

Xiangpu Railway, known as "the most beautiful express railway in China", is a national I-class express railway trunk line focusing on passenger transport and freight transport, and it is also a world-class express railway, which is located in tunnels and viaducts almost all the way, making it extremely difficult to build. The line is located in eastern Jiangxi and central Fujian. It was originally designed to start from Xiangtang Station in Jiangxi in the west, pass through Fuzhou, Nanfeng and Nancheng in Jiangxi, Jianning, Taining, Jiangle, Shaxian and Youxi in Fujian, and reach Meizhou Bay Port (Putian East Station) in Fujian in the east. Xiang-Pu Railway implements "passenger and freight separation", and then the starting point is changed from Lehua Station of Changjiu Intercity Railway in Xinjian County, Jiangxi Province to Nanchang West Station, and then to Xiangtang Station in the southeast to Fuzhou North Station. Nanchang West Railway Station is newly built in the passenger station, and the connecting line of Nanchang Station is introduced to connect with Lehua Station of Changjiu Intercity Railway. The freight starting point is the same as that of Tanggu Station. For Tangxi Station, Sanming North Station introduces the connecting line of Yingzha Line Laizhou (Waiyang) Station to connect Nanping Station, Yongtai Station introduces the connecting line of Waifu Line Duwu Station to connect Fuzhou Station, and the passenger terminal is Shanghai-Shenzhen Line (Fuxia Line) Putian Station. The freight terminal is newly built Putian East Station, which is Meizhou Bay Port.

Xiangpu Railway branches from Nanchang West, xiang tang, Fuzhou Station, Nancheng, Nanfeng, Jianning, Taining, Jiangle, Shaxian and Youxi to Yongtai, and is introduced into Fuzhou Station of Waifu Railway and Putian Station of Fuzhou-Xiamen High-speed Railway respectively. Xiangtang Station is a marshalling station. Xiangpu Railway is under the jurisdiction of Nanchang Railway Bureau. The line connects Hangzhou-Nanchang Passenger Dedicated Line and Beijing-Kowloon Railway in the west, yingtan-xiamen railway in the middle, and Shanghai-Shenzhen Railway (fuzhou-xiamen railway) in the east, which is one of the important passages connecting Jiangxi and Fujian provinces. There are railways from Shangrao, Jiangxi to Fuzhou (Waifu Railway, Hengnan Railway, etc.) near Xiangpu Railway. Yingtan-xiamen railway's Jiangxi yingtan-Fuzhou Railway, Hefu Expressway (Fujian passes through Jiangxi to Anhui), Fuyin Expressway (Fuzhou to Jiangxi, Hubei, Shaanxi, Gansu, Ningxia, etc.), Nansanlong Expressway, Pujian Longmei Railway, Quannan Expressway (Quanzhou passes through Sanming, Jiangxi, Hunan to Guangxi, Xiarong Expressway (Fujian passes through Jiangxi, Hunan Guizhou to Chengdu, Sichuan), Ningshang Expressway.

because of the journey, most goods from Hunan and Jiangxi do not choose Fujian's port, but choose to go directly to Guangdong. The journey of Jiangxi's goods exported to Southeast Asia and Europe by sea from Guangdong is closer, and there is a similar situation in Hunan. The goods from Hunan and Jiangxi are exported to Japan, South Korea and the United States from the Yangtze River to Shanghai, which is short, with large volume and low cost. Hubei, Anhui and Fujian are separated from Jiangxi, while Hunan and Jiangxi directly go south, which is a large area of flat land in Guangdong, and the terrain in Fujian is complex. Jiangxi Ganjiang River goes straight to the Yangtze River and reaches the mouth of the Yangtze River in Shanghai. Since ancient times, the trunk and tributaries of the Yangtze River have been the main artery of water traffic in the south of China, which runs through the east and west and connects the north and the south vertically. Large-capacity ships can reach Nanjing, Hankou, Chongqing and Yibin. The total investment of Xiangpu Railway Project is 51.6 billion yuan. Xiangpu Railway is a fast railway passage from central and western China to Meizhou Bay Port in Putian, Fujian.

The whole running time of Xiangpu Railway does not exceed 3 hours, but it passes through seven scenic spots, such as Sanqingshan, Wuyishan, Yuhua Cave, Dajin Lake, Jinrao Mountain, Daiyun Mountain and Qingyun Mountain. These scenic spots include national 4A-level scenic spots and national ecological protection zones, with dense vegetation and various rare wild animals along the line. Xiangpu Railway is called "the most beautiful railway line". Total length of the main line: from Xiangtang Town, Nanchang County, Jiangxi Province in the west to Putian City, Fujian Province in the east, the total length of the main line is 632.359 kilometers.

design speed: design speed is 2km, and freight speed is 12km.
