According to the BBC - "Brian Cooke, chairman of London Travelwatch, said there was no system available that could cope with the volume of Tube passengers.
He said everyone wanted maximum security but there were concerns the checks would mean more delays and congestion."
Back in Metro - "Transport for London added 'Body scanners are completely impractical on the London Underground. Heathrow handles 67.1 million passengers each year - London Underground carries 976 million.
'You can just imagine the delays if such technology was introduced on the Tube. We are constantly reviewing technology to see what could be potentially employed - but body scanners are not an option for us. Our stations just don't have room for them'
So what is it lads, too many delays and impractical or not enough room or both?
