This looks very good but, I am curious how Prince Edward can keep cool. Since he has not got his outer shell (boiler cover) on. I am sure it can be clearly and simply explained to someone like myself to understand.
the boiler cover is actually to keep the heat in not out. running without it simply lowers the thermal efficiency of the boiler which means using more coal and water other then that it doesnt have much of an effect.
Yes, I understand. My thought was that the boiler cover was where the water is stored. And yes, I realise about keeping heat in but, I thought without the outside.. well I guess with the outside air, that would keep the temperature down. I admit there is gaps in my knowledge but, I was thinking how the water gets from the tender to be turned into steam.
englishtwister the boiler itself contains the water the fire being contained inside in a sepirate area with tubes to carry the smoke to the smokebox. This also acts as extra heating area. The boiler "cover" is only there to look pretty and contain the insulation. It does not itself carry water or hold pressure.
englishtwister the boiler, as the name suggests, is nothing more than a giant kettle, the fire (at the rear of the boiler) produces intense heat, which passes through a number of tubes, through the boiler to the front end (the smokebox) and exhausted through the chimney, the tubes enabling a large heating area to boil the water and produce steam. The water supply in the tender is delivered to the boiler via piping, and an injector system, specially designed to deliver the water, against the pressure of the boiler. The boiler cladding, as noted by others is purely cosmetic, and with heat-resistant material between the boiler and the cladding, this serves to keep the heat in the boiler, and the cladding comparatively cool. Hope this helps.

englishtwister she was only steamed for 2 runs before the clading and bodywork were put on

wish I could get that one 4-4-0 USA loco
It's a very nice loco, I hopefully will be going back soon and seeing her run again.
