Beijing subway line gets safety doors

Sliding security doors are being installed at Yong'anli station on Beijing's Subway Line 1, the oldest station in the capital without such protective equipment.

Unlike the full-height doors that reach almost to the ceiling in other stations, the ones used at Yong'anli are "half-height", or about 1.5 meters tall.

Running roughly along iconic Chang'an Avenue, Line 1 opened in 1971 and was put into civil use in 1981.
