X-Ray Machine - 28

To ensure public safety during the 2008 Summer Olympic and Paralympic Games, the subway initiated a three-month heightened security program from June 29 to September 20, 2008. During this period, riders were subject to searches of their persons and belongings at all stations by security inspectors using metal detectors, X-Ray machines and sniffer dogs. Items banned from public transportation such as "guns, ammunition, knives, explosives, flammable and radioactive materials, and toxic chemicals" were subject to confiscation. The security program has been reinstituted during other times of high ridership such as the 2009 New Year Holiday.
