The Fuzhou Metro is a rapid transit system serving the city of Fuzhou in Fujian province of China. Currently, the Fuzhou Metro network consists of four lines. They are operated by Fuzhou Metro Group (Lines 1, 5, 6), and Fuzhou CETC Rail Transit Company (Line 2), respectively. Fuzhou Metro was approved for construction on June 3, 2009. The testing service, closed to the public, began on 30 December 2015 and ran for three months. Line 1, the initial line of the Fuzhou Metro, began operations in 2016, running from the southeastern to the northwestern parts of the city. Since then, the metro network is likely to expand with the addition of more lines, stations and infrastructure.
