What lurks beneath? Andrew Ian Dodge worries...
In London we dig underground deep into the cold soil to make room for our trains and tunnels.Thousands of workers and machines toiling in the earth. Amongst the workers, who work 24/7, are a few people whose task is to provide safety. They aren't health & safety people; but dedicated individuals who make sure that all the tunnels are properly protected.
Those marks you see speeding along in the tube or in your car are not graffiti or left over from construction. They are wards against some of the other things that reside in the earth.
Very nasty things.
