Line 4 (Changchun Rail Transit)

Line 4 of the Changchun Rail Transit is a grade separated light rapid transit line in Changchun, running from north to south. Although it uses extended low floor LRVs, the line operates more like a metro, being entirely separate from traffic, similar to the Seville Metro in Spain and U6 of the Vienna U-Bahn.

Line 4 was opened on 30 June 2011. It is currently 20.8 km long with 21 stations.
