Segments

Chengdu–Ya'an segment
Ya'an Railway Station

The Chengdu to Ya'an segment begins at Chengdu West Station where it branches off from the Chengdu–Pujiang intercity railway. The 94-kilometre-long (60 mi) segment is electrified, double tracked, and has a design speed of 200 kilometres per hour (120 mph).[2] It began operation on 28 December 2018.

Ya'an–Kangding segment

The Ya'an to Kangding segment is currently under construction. The 193-kilometre-long (120 mi) segment will be electrified and has a design speed of 160 kilometres per hour (100 mph).

Kangding–Nyingchi segment

The Kangding to Nyingchi segment was scheduled to begin construction in 2020 after the approval in May 2019 .[3] The 998.61-kilometre-long (620.51 mi) segment will be electrified and has a design speed of 160 kilometres per hour (100 mph). The route is expected to roughly parallel that of China National Highway 318. As this section contains some of the roughest terrain on the railway, construction from Kangding to Nyingchi is expected to last seven years and done in 2030 and cost 270 billion yuan ($41.347 billion).[4]

Nyingchi–Lhasa segment

The 435km Nyingchi to Lhasa segment is currently under construction. The 434-kilometre-long (270 mi) segment has a design speed of 160 kilometres per hour (100 mph).
