For the railway connecting Xining and Chengdu via Huangshengguan that is currently under construction, see Xining–Chengdu high-speed railway.
Xi'an–Chengdu high-speed railway or Xi'an-Chengdu Passenger Dedicated Line, is a dual-track, electrified, high-speed rail line in Western China between Xi'an and Chengdu, respectively the provincial capitals of Shaanxi and Sichuan. This line, which commenced operations on 6 December 2017, runs 510 km (320 mi) through Shaanxi and Sichuan provinces and accommodates trains traveling at speeds up to 250 km/h (160 mph).[1] Travel time between the two provincial capitals was reduced from 16 to less than three hours.[2]
Over much of its length, the Xi'an–Chengdu Passenger Dedicated Line largely parallels existing railways: the Yangpingguan–Ankang railway in southwestern Shaanxi (between Hanzhong and the Yangpingguan junction), and the Baoji–Chengdu railway in Sichuan (from Yangpingguan to Chengdu). However, the section from Xi'an to Hanzhong, crossing in tunnels under the Qin Mountains, follows an entirely new direct route.
High speed rail reforms meant direct Chengdu-Lanzhou and Chongqing-Xi'an services would use a combination of Xi'an–Chengdu high-speed railway and Chongqing–Lanzhou railway from where they met at Guangyuan. This would negate the need to build a separate direct Chongqing-Xi'an or Chengdu-Lanzhou lines.[6] However, with the announcement of the expanded 8+8 high speed rail grid, the two originally planned lines were reinstated in the masterplan.[7]
The Chengdu-Xi'an HSR have to cross the Qin Mountains; to achieve that, trains must climb continuously at 2.5% inclination (2.5 meters up per 100 meters run) for 47 kilometers.[citation needed] Since most HSR trains with 250 km/h maximum speed are not equipped with sufficient redundant power to maintain max speed climbing, trains scheduled to run between Chengdu and Xi'an using 250 km/h max speed equipments have to reserve extra time for the tunnel. However, for trains that continue to Beijing via Xi'an-Zhengzhou High Speed Rail and Guangzhou-Beijing High Speed Rail, an equipment capable of 350 km/h operations must be utilized to reach regular speed on the Zhengzhou-Beijing part. With redundant power equipped for 350 km/h operations, they lose less speed going up the tunnel, thus spending less time; this has reportedly caused these trains to have to reduce speed to maintain proper separation.
