Hanguangxian

Hanguangxian (Baiyu: 含光线) is a metro line in Xiongjing, Bai Empire. Coloured gold on official maps, the line is 53 km long with 41 stations. The line runs mainly underground, from Hanbu at the east to Huangtuo at the south, via Wangyuan, Guang'an and Kefeng.

The line, from Hanbu to Guang'an, was constructed during the city's preparations for the 1988 Geolympiad Games. Its name was derived from the original two termini of the line. At the same time, plans were drawn up for a line connection to Huangtuo from Kefeng. These plans were revised as the Hanguangxian's southeast extension. After much deliberation on the line alignment between Guang'an and Kefeng, the extension began construction in 1992 and was completed in 2001.
