Metro adds safety doors

Metro operators will install safety doors on the city's elevated subway platforms, the Shanghai Evening Post reported Tuesday.

The doors are slated to be installed in the above-ground stations on lines 1 and 5 before next May. The metro operators said they will install the doors in the elevated stations of lines 2, 3, 4, and 6 by 2015. Workers will have to remove the platform's guardrails before adding the doors.
