Line 21 of the Guangzhou Metro (Chinese: 广州地铁21号线; pinyin: Guǎngzhōu Dìtiě Èrshíyīhàoxiàn) is a rapid transit rail line under construction in Guangzhou. Line 21 is a express suburban metro line along with Line 14. Both lines are 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 will have passing loops to allow for express and local stopping patterns. The trains in Line 21 will reach a maximum service speed of 120 km/h. These considerations will allow for passengers to travel from outer Guangzhou to the city center in one hour. It is planned to run from Yuancun in Tianhe to Zengcheng Square in Zengcheng. The Line is about 61.5 km long. The line will have 40.1 km of underground sections, 6.8 km of mountain base tunneling and 14.7 km on viaducts. The line will have a total of 20 stations, of which 17 will be underground and 3 will be elevated. Line 21 is currently under construction and is expected to be operational by the end of 2018.
