The trains are manufactured by CRRC Tangshan, while the permanent magnet synchronous traction system is produced by CRRC Times Electric. This is the second application of the technology on metro trains in China after Changsha Metro.

The permanent magnet synchronous traction system weighs less than conventional traction equipment, is more efficient and generates less noise. As a result, Xiamen Metro expects the new trains to consume less energy than the trains it currently operates.

Line 2 is 41.6km long and runs from Wuyuanwan in the west through the city centre, which is located on an island, to Tianzhushan in the east. Line 2 opened on December 25 2019.
