    In the book regarding Boiler Explosions by Hewison, it dismisses the 'water flashing to steam' theory as not being what really happens in a boiler, though commonly raised throughout the early history of boiler explosions in the UK. Apparently tests were carried out which disproved the theory.

    Have George Stephenson's original 'Rocket' or any of the other surviving locos of that period still got tubes in them?

    Rocket definitely hasn't. Most of the valuable metals were stripped before it was preserved, so no copper tubes. The firebox still has the back plate (which was iron) but the water jacket (copper) is long gone.

    Has Derwent got any tubes in it? I can't off hand remember which version of Hackworth's boiler designs it has - some had a single outward flue but return tubes.
