The LRVs will operate without overhead catenary on 90% of these lines using Bombardier's Primove system. The Hexi New City line will receive eight vehicles which will serve 13 stations, while the Alin line, which features steep gradients and partly-elevated sections over highways, will receive seven vehicles. The LRVs will enter revenue service in 2014.

CSR Puzhen will build the vehicles at its plant in Nanjing with Bombardier set to supply the propulsion and control equipment under a 10-year technology license agreement signed in 2012, which enables CSR Puzhen to sell and manufacture low-floor LRVs using Bombardier technology in China. Each of the 32m-long, 2.65m-wide LRVs will be equipped with two Lithium-Ion battery systems which are recharged during acceleration and designated stops.

The Nanjing contract is CSR Puzhen's second low-floor LRV order in China since it signed the technology agreement with Bombardier after it secured a contract with the city of Suzhou for 18 trams in January.
