The 9.4km line will connect the tourist destinations of Yiheyuan and Xiangshan in the city's western suburbs and will include catenary-free sections totalling 4.4km.

The 100% low-floor five-section bidirectional LRVs will have an entry floor height of 350mm.

The vehicles will be based on AnsaldoBreda's Sirio design, which was licensed to CNR Dalian by the Italian supplier in a 10-year deal signed in 2012. Ansaldo STS has also licensed its Tramwave catenary-free electrification system to CNR Dalian and China's General Resources Company.

AnsaldoBreda's share of the Biejing contract is worth €19m and includes traction equipment for all 31 vehicles as well as the train control monitoring system (TCMS).
