LONDON, Jan. 11 (Xinhuanet) -- Hi-tech terrorist detectors are to be tested at a London railway station, local media reported on Wednesday.

    The new measures, which were announced last autumn by Britain's Transport Secretary Alistair Darling, will run a four-week trial starting Thursday.

    One of the detection devices is a millimeter wave scanner which can screen for concealed weapons and detect traces of explosives, Sky news reported on Wednesday.

    Another is a so-called "intelligent" CCTV system that sets off an alarm when it spots unusual behavior.

    The trial comes six months after the July 7 bomb attacks on the London Underground stations and a double-decker bus.

    Trials will involve passengers on the Heathrow Express, which runs from a west London train station to Heathrow Airport.

    It is believed that the technology could be extended to other stations and possibly the underground system well.

    However, Transport Secretary Darling noted that security on the rail and subway networks could never be as tight as it is at airports.

    "You just simply couldn't have people queuing up for hours to get through - you would be doing the terrorists' job for them," he added. Enditem
