Looking good. What are your thoughts on subtly 'flattening' tyres to make models 'sit' on the road more credibly?

(If I remember rightly) it's called "French Second Empire" style, characterised by mansard roofs. Quite why it was seen as appropriate for GWR station buildings, I cannot imagine.

I'm not sure that Percy Emerson Culverhouse was any more on the right lines.

Though I used to live in Truro and used that station, the early railways' classical-style termini were for me in better architectural taste (even if few survive), and even recent developments like KX seem to work well. But I am enjoying seeing this model build.

Looking very good. Reads as if you are rising to a significant challenge at that size.

Walls and gables? Hopefully you will get further than the current condition of Invershin on the Far North line.

A really significant problem with the principle of the atmospheric railway is that the force available to move the train is limited to something less than one atmosphere times the surface area of the piston. I've no idea if the technology of the day would have coped any better with a positive pressure system! (Which, in principle, would have the same advantage as that of air brakes over vacuum brakes.)

Or a high pressure steam engine over a Newcomen engine?
