Life in the Castle
After a bit more work, the castle conversion now looks like this:

and what's more, it runs like this:
Towards the end of the run it was suffering from a slight slow down every 4th turn of the wheels. I have others that do this, but haven't figured out a decent fix yet, something to do with the timing shaft I believe.
There's no whistle at the moment as I haven't worked out how to fit one in. I did cut one down until it fitted, but by that time it had stopped whistling (or maybe only so dogs could hear it). Also, there's no coupling at the rear of the tender yet.
And then it will need a bit of paint.
More updates as and when,

The castle lives - see video from last weekend at SVR:
The main problem was the heat loss through the body casting. By the time it had reached a proper running temperature, there wasn't much water left in the boiler, so it was a fairly short-lived running time. I will add some more insulation above the superheater and try again at the next club outing.
Fingers crossed that does the trick!
