一路向西 回到拉萨

從成都出发，沿318国道一路逶迤向西，跨越数不清的山岭、江河、草原与冰川，最终抵达拉萨。这条交织着艰险与浪漫、远古与神秘的旅途，即将展开。

日前，由中铁二院工程集团有限责任公司牵头编纂的《川藏铁路勘察设计暂行规定》（征求意见稿），正式对外公布征求意见。文件首次明确披露川藏铁路设计标准为时速200公里，建成后，从成都坐动车去拉萨，将从36小时减少到约13小时！

川藏铁路是公认“最具挑战的铁路工程”，你能想象一列列现代化动车在峡谷高山之间往来穿梭吗？这将是多么动人心魄的梦幻之旅。

今天，让我们提前穿越时空，去一探她的盛世美颜吧！ Departing from Chengdu， you can drive along National Highway 318 westward across numerous mountains and ranges， rivers， grasslands， and glaciers before arriving in Lhasa finally. A journey combining hardships， dangers， romance， antiquity， and mystery begins.

Currently， Temporary Provisions on the Survey and Design of Sichuan-Tibet Railway （revised draft for comment）， compiled by China Railway Eryuan Engineering Group Co.， Ltd. （CREEC）， was made public for comments. For the first time， the document reveals that the design speed of Sichuan-Tibet Railway is 200km/h. After completion， a bullet train will take passengers from Chengdu to Lhasa with a journey of only 13 hours， rather than the previous 36 hours.

Just imagine， how exciting it will be to have a bullet train trip across valleys and hills along “the most challenging railway project”.

Let’s go to unveil the mystery and beauty of such a journey.
