On this blog, when we refer to a Tornado, we mean the world's newest steam engine, built from scratch using original plans for the Peppercorn Class A1 that saw their heyday in the 1960s. A wonder to behold (though neither of us has yet to catch up with her - when we do, the video will be uploaded to our YouTube stream).
Elsewhere, a reference to a Tornado means something very different. The following video shows how a goods train in the USA is affected as it passes through one of these destructive winds. Keep with the video, though, as the action doesn't get going until after 1:05, but the fall-out is truly astonishing.
We are fortunate that we seldom suffer from winds of this strength here in the UK.
