The 10-station Yanfang Line will run for 15.2km from an interchange with the Fangshan Line at Cheliangduan station to Raolefu, where the line will divide into two branches serving Zhoukoudianzhen and Yanhua. Commercial services are expected to begin in December 2015.

This is the first UTO installation in China with all subsystems developed and supplied by a domestic manufacturer. The line will be equipped with communications-based train control (CBTC) supplied by Beijing Traffic Control Technology and CNR says automation systems on the line will meet IEC 62267 standards at Grade of Automation (GOA) Level 4.

The stainless-steel Type B trains will have a maximum speed of 80km/h. The first two trains will be delivered in May 2015.
