Chengdu–Lanzhou high-speed railway has a length of 730.549 kilometers, of which 462 km is new trackage. It is being built as a double-track electrified railway, at the national railway line class I level. It will have an overall design speed of 200 km/h; however, the Chengdu-to-Jiuzhaigou section will have a reduced speed of 174 km/h in sections, due to the difficult and mountainous terrain. The total investment is expected to be 61.939 billion yuan. Construction commenced on February 26, 2011.
After the completion of the railway, the distance between Lanzhou and Chengdu will be shortened from 1,172 km of conventional rail lines to 730 km of high-speed rail. Run time for train services will be reduced to about 5 hours.
Chengdu–Lanzhou high-speed railway will head north from the Chengdu hub to Qingbaijiang through Shifang, Mianzhu, Anxian and tunnelling through Longmen Shan to Maoxian, tracing along the Minjiang River valley and on through Chuanzhusi to Jiuzhaigou County. Crossing into the territory of Gansu, across the Bailong River, it joins the Lanzhou-Chongqing HSR at Hadapu, using that railway line to the terminus at Lanzhou East Station.
