↑ Wuhan, along with other three Chinese cities, has been the first batch to be approved to build so-called "light rail" system in China since 2000, see 2000年，国家批准长春、大连、武汉和重庆4个城市为首批轻轨建设示范城市。. However, Changchun built a true light-rail system, Dalian built a metro-style commuter rail system (and is referred to as "kuai-gui 快轨", not "qing-gui 轻轨"), and Chongqing opted for a monorail system, whereas Wuhan was the only one to build an elevated metro system. See "Urbanrail--Wuhan and affiliated Wikipedia pages.
