Future development
edit- Phase 2
Phase 2 of Line 3 is still in long-term planning.[1] It will be an extension from the southwest terminus of Phase 1, Yuhuazhai station to Kunmingchi station (tentatively named). After the completion of Phase 2, Line 3 will have 30 stations (an addition of 4 to Phase 1) and a length of 50.5 km (31.4 mi) in total.[1]
Rolling stock
editThe rolling stock consists solely of CNR DKZ17 trains manufactured by CNR Dalian, 41 trainsets will be provided as per the first contract.[7] The trains run in six-car formation, with four motor cars and two trailer cars, which is different from previous trains (running in 3-3 formation), as more power is required to drive the trains up the ramp from underground to overground sections.[7]

Train Control
editLine 3, as all the previous lines, uses Trainguard MT CBTC signal system manufactured by Siemens[8][9] to enhance the safety of the automated, driverless trains.
Incidents
editDefective cable incident
editOn 13 March 2017, a post titled Do you still dare to take the Xi'an Metro? (西安的地铁你们还敢坐吗) was posted by an anonymous whistle-blower on an online forum.[10] The poster claimed that the electrical cables used on Line 3 of Xi'an Metro, which were produced by Shaanxi Aokai Electrical Cables (Aokai Cables), did not meet the safety criteria, specifically, the cross-sectional area was smaller than specified, which might lead to overheating of the cables, therefore presenting a fire hazard.
On 15 March, Aokai Cables released a statement that the claims were unfounded and they have filed a police report.
On 16 March, the official Xi'an Metro Weibo account announced that they had launched an official investigation and an internal audit. On the same day, the government of Xi'an pledged to investigate the matter.
On 20 March, the government of Xi'an told a press conference that none out of five cable samples sampled were of acceptable quality.
In the wake of the incident, 8 members of staff from Aokai cables were arrested and disciplinary actions were taken against 122 local officials, including 8 bureau-directors and 58 division heads.[11]
