Zhengzhou Metro (simplified Chinese:郑州地铁;traditional Chinese:鄭州地鐵;pinyin:Zhèngzhōu Dìtiě) is arapid transit rail network serving urban and suburban districts ofZhengzhou, the capital city ofHenan province. It is operated by the state-owned Zhengzhou Metro Group. As of December 2024, the network has 13 operational lines, with anetwork length of 450 km (279.6 mi)[4] and 217 stations. Opened on 28 December 2013,[3] it is the first metro system in Henan province, and 18th inmainland China.

The history of the metro network in Zhengzhou dates back to 1974, when the first metro project in Zhengzhou was planned. It was called as the "Project 7401", since it was the first project approved by the CPC Henan Provincial Committee in 1974. The project was designed for both civilian and military use, as a single track metro line in peacetime, and could be used for civil defense during war. The first phase was planned to start at Huayuan Road (near Zijingshan), then move westward via Erqi Square, and ends at the Cable Factory on Funiu Road, with 6 stations. Part of the planned route was similar to the route of the currentLine 1. Construction began in 1975, and stopped in 1980, when the project was finally called off. Some sections of the tunnels and one station in Bishagang (not the currentBishagang station) had been completed then. The completed station was transformed into an underground department store in 1982.[5]
In 2000, the planning of the current Zhengzhou Metro system was started. The plan had been adjusted several times, and was finalized in 2008. The first phase of the system, includingLine 1 andLine 2, was approved byNational Development and Reform Commission (NDRC) in February 2009.[6][7] Construction ofLine 1 started on 6 June 2009[8] andLine 2 started construction on 28 December 2010.[9] As planned,Line 1 andLine 2 commenced operations on 26 December 2013 and 19 August 2016 respectively. On January 12, 2017,Chengjiao line started operation. It is in through services withLine 2 and allows the system to serve theZhengzhou Xinzheng International Airport.[10]
In April 2014, the NDRC published the Construction Plan of Zhengzhou Rapid Transit System (2014-2020), marking the start of the second round of construction. The plan includes the Line 1 Phase II, Line 2 Phase II,Line 3 Phase I,Line 4, andLine 5, with a total length of 120.7 kilometres (75.0 mi).[11] The second phase of Line 1 was put into use on 12 January 2017,[10]Line 5 opened on 20 May 2019. Line 2 Phase II opened on 28 December 2019. Line 3 and Line 4 opened on 26 December 2020.
In April 2019, the NDRC approved the Phase III Construction Plan of Zhengzhou Rapid Transit System (2019-2024), marking the start of the third round of construction.[12] The plan includes the Line 3 Phase II, and the first phase of Line 6, Line 7, Line 8, Line 10, Line 12 and Line 14 with a total length of 159.6 kilometres (99.2 mi).[13] Line 10 and Line 14 are already under construction.[14] Line 14 was opened on 19 September 2019.[15]
Beginning on July 17, 2021, heavy rains occurred inHenan. The rainfall inZhengzhou from 20:20 on July 17 to 20:20 on July 20 reached 617.1 mm (24.30 in),[18] of which the rainfall within an hour from 16:00 to 17:00 on July 20 reached 201.9 mm (7.95 in). It broke through historical records, far exceeding the "24-hour rainfall exceeding 200 mm (7.87 in)" extreme rainstorm level designated by theNational Meteorological Center.[19]
On July 20, many stations were flooded with heavy water, which caused serious water accumulation.[20] A landslide accident occurred at a construction site ofLongzihu Xi[21] ofLine 12 in the morning, but no casualties were caused.[22]
At about 18:00 on July 20, rainwater entered the tunnel betweenHaitansi station andShakoulu station ofLine 5. A train was trapped in the tunnel and water flooded.[23] The water level in the car once reached the chest position, and passengers stranded in the car were trapped for several hours, until they were rescued and left the carriage.[23]The floods in Zhengzhou Metro killed 14 people.[24]
Zhengzhou Metro closed several stations, and then announced the suspension of operation of the whole system at 18:00 on July 20.[25]
Line 1, Line 2 (Liuzhuang to Nansihuan section) and Chengjiao line reopened on September 12. Line 2 (Jiahe to Liuzhuang section), Line 3, Line 4 and Line 5 reopened on September 15. Due to equipment replacement, Line 14 reopened later on 29 August 2022.[26]
Some of trains were damaged in the floods while they were in service or stabling in the depots. After the floods, most of them were taken out of service, received electrical reconstructions and tested before they returned to service.

Fares of Zhengzhou Metro are calculated by distance traveled, ranging from¥2 (within 6 km (3.7 mi)) to ¥9 (the longest journeys within the current system). A journey shorter than 6 km (3.7 mi) costs ¥2; ¥1 is charged for every 7 km (4.3 mi) after 6 km (3.7 mi), every 8 km (5.0 mi) after 13 km (8.1 mi), and every 9 km (5.6 mi) after 21 km (13 mi).[45] The system is free of charge for elderly citizens in Zhengzhou with ages above 60 during non-peak hours and on public holidays. Children under the height of 130 cm (51 in) may ride for free when accompanied by an adult. There are also student fares, which are half the adult fare, for full-time students enrolled in primary or middle schools.[45]
Single journey tickets can be bought on the ticket vending machines at every station. The passenger has to tap it on the sensor on the ticket gate when entering and insert it into a slot at the exit gate where the ticket is reclaimed.
