Line 21 is an express suburban metro line along with Line 14. Both lines were envisioned to connect and promote development in the northeast regions of Guangzhou. Line 21's unique role means that it has many design features that make it different from other Guangzhou metro lines. For example, several stations have passing loops to allow for express and local stopping patterns and trains reach a maximum service speed of 120 km/h (75 mph). These considerations allow for passengers to travel from outer Guangzhou to the city center in one hour.[2] Line 21 runs from Yuancun in Tianhe to Zengcheng Square in Zengcheng.[3] The line is about 61.5 km (38.2 mi) long.[1] The line has 40.1 km (24.9 mi) of underground sections, 6.8 km (4.2 mi) of mountain base tunneling and 14.7 km (9.1 mi) on viaducts.[4] The line has a total of 21 stations, of which 17 are underground and 4 are elevated.
The eastern section of Line 21 opened on 28 December 2018[5] and the western section opened on 20 December 2019.[6]
