The line is the first in Beijing to be capable of unattended train operations, and the first in China to exclusively use subsystems developed by domestic manufacturers.

Future Development

The 6.1 km (3.8 mi) branch line of Yanfang line, fromRaolefu stationto Zhoukoudian Town station is under planning. Due to low passenger flow, the branch line will not be built in the short-term planning. In addition, Beijing Subway is evaluating the possibile merge with theFangshan line.
