【凸峰運轉】坐了7小時火車、鑽了5小時山洞！基建狂魔的「新成昆鐵路」，妳必須要體驗壹下！ - 70 km of every 100 km of railway are tunnels！

坐7小時火車、鑽5小時山洞，這就是橋隧比超過70%的「新成昆鐵路」（成昆複線） - A 7-hour train ride and a 5-hour tunnel ride: this is the "New Chengdu-Kunming Railway" (Chengdu-Kunming Double Line), with a bridge-tunnel ratio exceeding 70%. 因爲老成昆線建設年代久遠（上世紀60-70年代），線路條件受限，已無法滿足成都~昆明間日益增長的客貨運需求，2019年起，「新成昆線」（成昆複線）分段逐步投入使用，頻繁使用「長橋梁」、「長隧道」，雙線電氣化鐵路最高時速達160km/h，徹底打通了「成昆瓶頸」！ - Because the old Chengdu-Kunming Railway was built a long time ago (in the 1960s and 1970s), the line conditions are limited and it can no longer meet the growing passenger and freight demand between Chengdu and Kunming. Since 2019, the "New Chengdu-Kunming Railway" (Chengdu-Kunming Double Line) has been gradually put into use in sections, frequently using "long bridges" and "long tunnels". The double-track electrified railway has a maximum speed of 160km/h, completely breaking through the "Chengdu-Kunming bottleneck"! 那麽今天，就跟著我的鏡頭，登上成昆「複興號」動車組 坐「複興號」、走新成昆！ - So today, follow me aboard the Chengdu-Kunming Railway's "Fuxing" EMU train. Ride the "Fuxing" and experience the new Chengdu-Kunming Railway!
