Sniffer dogs on Heathrow Express Trains
21.07.05
Sniffer dogs are being used across the London Underground and the Heathrow Express to detect explosives, in the wake of the London bomb attacks. Dozens of dogs are being used on trains, at ticket barriers and at stations after the blasts on 7 July.
Dogs were already being used on the Tube in east London to look for drugs and on the Heathrow Express to find explosives. Now they are being used across the Tube network, and will continue to be used 'indefinitely', British Transport Police (BTP) said.
The sniffer dogs being used, which tend to be labradors and spaniels, undergo an intensive eight weeks of training with their dog handler. The handlers watch to see if the dogs freeze or lie down when sniffing bags, which indicates that something is wrong.
BTP's team of 28 dogs are being used on Tube stations where the most people get on trains or where the network meets mainline rail lines, such as King's Cross and Victoria. A spokesman for BTP said: 'They operate just like dogs who search for drugs except they have been trained to sniff out explosives. The dogs are far more effective than any machine.'
