Re: Other escalator laws
No, they set up a special "small carry dog" training school. The dogs are trained to form an orderly pack at the entrance to the escalator and wait to be picked up by a human. They then wait for a lift at the exit - When the doors open and a sufficient number of dogs have entered the lift an especially trained intelligent dog (a Border Collie?) pushes the button to operate the lift. The dogs wait until the door opens after their trip and join the queue again at the entrance. The lift may need to be partitioned to keep the dogs separate from other travellers. I'm sure a Transport for London working group can be set up to carry out a feasibility study: Perhaps the dogs can also be trained to sniff for drugs or explosives on their human carriers?
