"Over the years the Flying Scotsman has travelled the world and been owned by pretty well everyone except my wife, and possibly Kate Moss. As I write he's for sale again, for a not inconsiderable 2.5 million Pounds. That may seem a lot for something that no longer has a purpose, even if he is Britain's engineering heritage. But he is not simply a machine. Like an Aston Martin DB7 or an F-16 fighter, he works as an art form too, a piece of sculpture. So what if you can't go anywhere in him anymore. Put him in your garden and spend your days just looking at him."
