On April 20, 1981, the Beijing Subway Company, then a subsidiary of the Beijing Public Transportation Company, was organized to take over subway operations. On September 15, 1981, the initial line passed its final inspections, and was handed over to the Beijing Subway Company, ending a decade of trial operations. It had 19 stations and ran from Fushouling in the Western Hills to the Beijing railway station. Investment in the project totaled ¥706 million. Annual ridership rose from 64.7 million in 1981 and 72.5 million in 1982 to 82 million in 1983.
