Thanks to CTOnews.com netizens for the clue delivery that you can change your name again! According to news from CTOnews.com on April 1, the official Wechat account of China Railway updated its article today, saying that with the completion of the last catenary wire, the catenary of the whole line of Guinan high-speed railway has been completed today, laying a solid foundation for the next step of line power transmission and joint test.

CTOnews.com learned from China Railway's official Wechat account that the catenary is an important part of the railway electrification project and a key equipment for the operation of high-speed trains. The train is connected with the catenary wire through the pantograph on the roof to obtain electric energy and provide power for the train operation.

Guinan high-speed railway is an important part of the Baobao (silver) sea passage in China's "eight vertical and eight horizontal" high-speed railway network. Construction of the whole line was officially started in December 2017, with a designed speed of 350 kilometers per hour and a total length of 482 kilometers. It is expected to open this year.

Tu Yuan: after the Chinese railway line is completed and opened to traffic, the train running time from Guiyang to Nanning will be shortened from more than 5 hours now to about 2 hours, and it will link up with Shanghai-Kunming, Chenggui and other high-speed railways. It has become a convenient and fast passenger transport channel from Sichuan, Chongqing and Guizhou to Nanning, Beibu Gulf, western Guangdong and Hainan.
