Line 8

Line 8 is an axle line coloured green. It is divided into line 8/N and line 8/S. Line 8 was originally dedicated to those who wanted to visit Olympic Park (Olympic Zone). It now gives access to Yanqing and Huailai via Huoying and the S2 line. It also interferes with the Changping Line at Zhuxinzhuang. The /S variant goes to Daxing via Fengtai.
