Changye -long high -speed rail Yizhou section enters the trial operation stage, and the traffic time of Yiyang to Changsha Railway is compressed to less than 40 minutes.

Changsha Evening News, Changsha, June 20 (All Media Reporter Wu Xinzan Correspondent Cai Zhen Liu Kai) The reporter learned from Guangtan Group that on June 20, the newly built Changyi Chang -high -speed rail Yiyang to Changsha section officially entered the trial operation stage, Hunan Fourteen cities and prefectures in the province are about to achieve full coverage and full -scale high -speed rail.

Changye Changzhong high-speed rail Yijiu section is located in the northwestern part of Hunan Province. It passes 6 counties and districts in 2 cities. Changsha-Yiyang-Changde City Industry Everbound Belt through Changzhutan City Group has a total length of 64.2 kilometers. There are 3 stations in Changsha West, with a design speed of 350 km/h, including 43 main line bridges and tunnels, and a bridge -tunnel ratio of 79.5 %. Construction started in June 2019.

The environmental protection requirements around the Changye high -speed high -speed railway are high, the geological conditions are complex, and the terrain and localforms are changing. Many bridges of the line need to cross obstacles such as railways and highways, and the construction is difficult. In order to realize the beautiful vision of Hunan Province's 14 cities and prefectures, and the railway construction department dynamically optimized the construction plan, the participating units implemented the rotation system construction, and took the initiative to abandon many holiday breaks. It has been promoted at high quality of engineering construction.

Since the long -term high -speed railway long section of the Changyi Changchang high -speed rail, the joint test of the long -term high -speed rail has successfully completed various tests such as the speed speed speed up and signal test testing of the EMU. It has the condition for entering the trial operation stage for nearly one year in the past one year in advance. Essence

"The trial operation of a new high -speed rail line is mainly based on the requirements of the test outline, and the test parameters of the train operation map, fault simulation, emergency rescue drill, and driving test of the driving test to provide a scientific basis for formal operation." Relevant technicians told reporters that, unlike the formal operating train, the operating test train does not carry passengers, and only simulates the passenger transportation business. Other technical parameters are basically the same as the high -speed rail trains that are officially opened. It also entered the "countdown" stage.

The Changye high -speed rail is not only an important part of the "Eight Vertical Eight Eight Hengsheng" Zhongyu Xiamen channel and the Hunan channel, but also a golden liaison line. It connects the Guizhou Chang Railway and Xiangchang Railway in the northwest. The middle section is connected to the Yilu Railway. From the Hunan, Jiangxi and Fujian area, the north -south direction connects North China, Central Plains, and Western Hubei to South China. After the operation of Yichang's first section, Hunan will achieve the goal of "city -pass high -speed rail". The high -speed rail pass from Yiyang to Changsha compressed from 70 minutes to 40 minutes. The time and space distance is of great significance to optimize the transportation structure of Hunan and promote economic and social development in the region along the route.
