Line 22 (Guangzhou Metro)

Route

The line currently runs from Panyu Square to Fangcun. It was originally planned to interline with Line 18 south of Panyu Square, and track connections remain at Panyu Square to allow this.

The line is an express subway line using 8 car Type D trains with an operating speed of 160 km/h (99 mph).^[8] There is provision for future express services, with passing loops at some stations.

Phase 1

Phase 1 of Line 22 received planning approval in March 2017 as part of the Guangzhou Urban Rail Transit Phase III Construction Plan (2017-2023), running from Wanqingsha in Nansha District to Bai'etan (now renamed Fangcun to match the Line 1 station^[9]) in Liwan District. It was proposed the southern section between Wanqingsha and Panyu Square would interline with Line 18, however this did not eventuate and that section opened with Line 18 only.^[10][11]

Phase 1 eventually was split into two stages:

North extension

The North extension of Line 22 will be 41.1 km (25.54 mi) in length with 10 new stations and be fully underground.^[15] The north extension will directly connect Guangzhou Baiyun Airport while passing through Guangzhou Railway Station and Guangzhou Baiyun Railway Station.^[14] On December 31, 2021, the North Extension started construction.^[16]

South extension

In 2019, Dongguan municipal government proposed Line 22 to be extended east beyond Panyu Square to Nansha Subdistrict and cross the Shiziyang Channel into Dongguan and beyond to Shajing Town in northern Bao'an District, Shenzhen.^[17][18] In 2020, Guangzhou Metro began soliciting bids to further investigate the extension of Line 22 into Dongguan and Shenzhen.^[19] The first section of this extension a 58.5 kilometres (36.35 mi) segment from Panyu Square to Chang'an, Dongguan were officially included in Guangdong's 14th Five Year Plan in 2021 with provisions for future extension and connection with the Shenzhen Metro.^[20][21] The extension to Shenzhen will connect Qingsheng, Jiaomen, Nansha Passenger Port, cross the Pearl River Estuary and extend to Dongguan and finally connect to Shenzhen Guangmingcheng High-speed Railway Station.^[14]

When complete a number of different services and express and local stopping patterns will be operated, including Shenzhen/Dongguan to Baiyun Station, Nansha Passenger Ferry Terminal to Baiyun Airport North, Nansha Passenger Port to Huachengjie, etc.^[22]
