You may remember that soon after 7/7, the government decided that the Tube would get Bomb detectors?

Well, after testing, it seems they have concluded that it would be impractical.

This is for three reasons:

It would slow the service in the rush hour too much. At the moment, using an oyster card (which TFL is encouraging everyone to do), it takes 2 or 3 seconds to get through the ticket barrier (assuming no queue). Assuming a bomb scanner takes 10 seconds (which, if I understand the technology, is rather optimistic), this multiplies the delay by at least 3 times. Not a problem if you scan one or two people. If you have to scan 1,500 in a hour, it becomes an issue.
Any queues caused would be easy targets for terrorists. The terrorist may well be stuck in the Ticket Office. Along with the poor sods stuck waiting to be scanned.
Space.

Funnily enough, I remember thinking of those problems at the time.
