Beijing has instituted airport style security checks at several subway stops around the city, leading to huge queues and delaying commutes.
Body scanners were installed at the Bajiao Amusement Park station on Line 1, Tiantongyuan North station on Line 5, and Longze station on Line 13 in an effort to beef up security in response to heightened concerns over terrorism. It is unclear why these stations in particular were chosen for additional security.
Photos posted online showed huge queues to get into the subway system. The Beijing metro is already one of the world's busiest, where massive lines are a common sight.
