Transcriptions
Standard Mandarin
Hanyu Pinyin	Xīchéng Kèyùn Zhuānxiàn

Xi'an–Chengdu high-speed railway orXi'an-Chengdu Passenger Dedicated Line, is adual-track,electrified,high-speed rail line inWestern China betweenXi'an andChengdu, respectively the provincial capitals ofShaanxi andSichuan. 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]

The project was approved by theState Development and Planning Commission in October 2010.^[1] Construction of the Sichuan section of the railway started on November 10, 2010,^[3] and of the Shaanxi section, on October 27, 2012.^[4] The line traverses the ruggedQin andDaba Mountains and connects theGuanzhong Plains with theSichuan Basin.

The line is part of theBeijing–Kunming corridor.

Route

[edit]

The high-speed rail line connects Xian, in theWei River Valley,Hanzhong, in theHan River Valley, andGuangyuan,Jiangyou andChengdu in the Sichuan Basin. In the Qin Mountains, it has 127 km (79 mi) of tunnels, including six over 10,000 m (6.2 mi) in length.^[5] The railway passes under ecologically sensitive areas including the Taibaishan and Hanzhong Crested IbisNational Nature Reserves, which are home to theendangered giant panda,golden snub-nosed monkey,takin andcrested ibis.^[5]

Over much of its length, the Xi'an–Chengdu Passenger Dedicated Line largely parallels existing railways: theYangpingguan–Ankang railway in southwestern Shaanxi (between Hanzhong and theYangpingguan junction), and theBaoji–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 andChongqing–Lanzhou railway from where they met atGuangyuan. 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 viaXi'an-Zhengzhou High Speed Rail andGuangzhou-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.
